Rising Greenhouse Gases in the Air to Bring Stormy Weather

Monday, November 28th, 2011

The three gases that contribute the most to global warming rose to their highest levels ever, according to the United Nations (UN). Carbon dioxide, the most significant heat-trapping gas, rose 0.59 percent to 389 parts per million molecules of air, the UN’s World Meteorological Organization (WMO) said.  Methane rose 0.28 percent to 1,808 parts per billion; and nitrous oxide gained 0.25 percent to 323.2 parts per billion.  Rising greenhouse gas emissions threaten to “close the door” on limiting global temperature rises to two degrees Celsius (3.6 degrees Fahrenheit) during this century, according to the International Energy Agency (IEA).

“Even if we managed to halt our greenhouse-gas emissions today, and this is far from the case, they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate,” WMO Secretary-General Michel Jarraud said.

Even worse, greenhouse gases rose faster in 2010 than the average over the past 10 years, according to the annual Greenhouse Gas Bulletin.

Unfortunately, the report is bad news for the earth. Climate change will make droughts and floods like those that have battered the United States and other countries in 2011 more frequent, according to a new report, the U.N. Intergovernmental Panel on Climate Change.  The report, that follows a two-year process, suggests that researchers are far more confident about the prospect of more hot weather and heavy rains than they are about how global warming is impacting hurricanes and tornadoes.  The new analysis highlights a broader trend: The world is facing a new reality of more extreme weather, as policymakers and business are beginning to adjust.

Gerald Meehl, a senior scientist at the National Center for Atmospheric Research and one of the report’s reviewers, said it highlights why climate change is more than just a gradual rise in the global temperature reading.  “The fact is, a small change in average temperature can have a big impact on extremes,” Meehl said.  “It’s pretty straightforward. As average temperatures go up, it’s fairly obvious that heat extremes go up and (the number of) low extremes go down.”

“The time is now for this report,” said University of Illinois climate scientist Don Wuebbles, citing recent studies linking climate change to extreme weather.  “Scientific studies such as a report in the journal Nature have linked the deadly 2003 heat wave in Europe to climate change.”

CO2 levels are currently 389 parts per million, an increase from approximately 280 parts per million 250 years ago. According to WMO Deputy Secretary-General Jeremiah Lengoasa, CO2 emissions are to blame for about 80 percent of the rise.  But he noted the delay between what is emitted into the atmosphere and its impact on climate.  “With this picture in mind, even if emissions were stopped overnight globally, the atmospheric concentrations would continue for decades because of the long lifetime of these greenhouse gases in the atmosphere,” he said.

Representatives from a majority of the world’s nations are gathering to try to agree on how to avoid the worst of the climate disruptions that experts say will result if concentrations hit 450 parts per million.  At the present rate, that could happen within several decades, although some climate activists and at-risk nations say the world has already passed the danger point of 350 parts per million and must be undone.  According to the WMO, the 2.3 parts per million increase of CO2 in the atmosphere between 2009 and 2010 shows a speeding up when compared with the average 1.5 parts per million increase during the 1990s.  Since 1750, the WMO says, atmospheric concentrations of CO2 have jumped 39 percent; nitrous oxide has gone up 20 percent; and methane concentrations soared 158 percent.  Fossil fuel-burning, loss of forests that absorb CO2 and fertilizer use are the primary culprits.

Earlier this year, BP released data showing that global carbon dioxide emissions grew at their fastest rate since 1969 in 2010, as nations recovered from economic recession.  According to the WMO, greenhouse gas concentrations in the atmosphere rose by 1.4 percent last year from 2009 and 29 percent since 1990.  The WMO measured the global amount of greenhouse gases in the atmosphere, gathered from monitors in more than 50 nations, including natural emissions and absorption processes – known as sources and sinks – as well as human activity.

The WMO noted that methane is increasing following a brief period of “relative stabilization” between 1999 and 2006.  “Scientists are conducting research into the reasons for this, including the potential role of the thawing of the methane-rich Northern permafrost and increased emissions from tropical wetlands.”

As Weather Warms, Some Animals and Plants Get Smaller

Wednesday, November 2nd, 2011

Whether it’s the polar bear or the petite house sparrow, many of Earth’s species seem to be shrinking in size, a new study reports; its authors believe that is likely a result of global warming.  Other experts disagree, noting that the conclusion goes too far, and that global warming should not be blamed for what could be natural changes.  The research was published in the journal Nature Climate Change. 

The study found that 38 of 85 animal and plant species showed a definite reduction in size over decades, including a type of Scottish sheep that is now five percent smaller than a quarter century ago.  Those studies examined species over different time periods and in diverse numbers.  According to the study, species that are getting smaller include cotton, corn, strawberries, bay scallops, shrimp, crayfish, carp, Atlantic salmon, herring, frogs, toads, iguanas, hooded robins, red-billed gulls, California squirrels, lynx and wood rats.  The study notes that the house sparrow’s weight has dropped by one-seventh between 1950 and 1990.  A bird known as the graceful warbler showed a 26 percent weight loss during the same timeframe.

“There is a trend in a number of organisms across the board from plants to big vertebrates getting smaller,” said study co-author Jennifer Sheridan, a biology researcher at the University of Alabama.  “The theory is as things get warmer they don’t need to grow as large.”  The majority of these animals are cold-blooded, so the warmer the weather the faster their metabolism and the more calories they burn, according to Sheridan.  A biological law, called Bergmann’s rule, says that as the weather gets colder, animals get bigger.  This is the unwritten flip side of it, Sheridan said.

Yoram Yom-Tov, a zoologist at Tel Aviv University whose studies Sheridan used in her research, agreed that many species are shrinking, and noted that global warming isn’t the only reason.  “Changes in body size are a normal phenomenon,” Yom-Tov said.  “When conditions are favorable, they increase in size or reproduce at higher rates, and when conditions are deteriorating, they do the opposite.  I think that most species will adapt to climate change and survive.  No need for alarm.”

Many scientists believe that the study confirms that climate change is shrinking many plant and animal species and is likely to have a negative impact on human nutrition in the future.  Warmer temperatures and increasing variability in rainfall are affecting the size of all species in the ecosystem from microscopic sea organisms to land-based predators.  “Our study suggests that ectotherms (cold-blooded animals like toads, turtles, and snakes that rely on environmental heat sources) are already changing a lot,” said David Bickford from the National University of Singapore and the study’s co-author.  “What was most surprising to me was that it was such a uniform signal across all these different organisms,” Bickford said.

Sheridan and Bickford examined fossil records, which they found to be clear-cut: past eras of rising temperatures saw both marine and land organisms becoming progressively smaller.  During a time of warming 55 million years ago — often viewed as an analogue for current climate change — beetles, bees, spiders, wasps and ants shrank by 50 to 75 percent over a period of several thousand years.  Mammals such as squirrels and wood rats also shrank by about 40 percent.

Because warming is occurring at unprecedented rates, “Many organisms may not respond or adapt quickly enough”, especially those with long generation times, according to Sheridan and Bickford.  “We do not yet know the exact mechanisms involved, or why some organisms are getting smaller while others are unaffected.  Until we understand more, we could be risking negative consequences that we can’t yet quantify.”

Stanford biologist Terry Root, an expert in climate change, said the study’s conclusions “seem kind of far-fetched.”

Writing for the Nature.com news blog,  Susan Young says that “Temperature-linked changes in precipitation also affect the size of organisms.  Higher temperatures lead to drier environments, and Sheridan and Bickford suggest that reductions in size will be most pronounced in areas where global warming causes reduced precipitation as well.  Tropical trees, toads and mammals are known to grow slower during drought years and under experimental drying conditions.  Other environmental changes will also affect life on earth.  As the atmosphere loads up with carbon dioxide, so do the planet’s oceans, which raises the acidity of the water.  Higher acidity reduces the rate at which organisms like corals and oysters can form their shells.  The result, the authors say, is that these ocean creatures shrink.  The growth of red algae and phytoplankton are also hampered by the lower pH.  The authors note that the warming-shrinking trend does not apply to every organism, such as those with longer generation times or some at higher latitudes.  This variation exacerbates the problem.  If all organisms in a given ecosystem shrank on scale with one another, smaller predators could eat smaller prey that eat smaller plants, and all would be fed.  But that is not what ecologists are observing.  Organisms change with variable intensity depending on their lineage, size and location, and ecosystems are likely to be thrown off balance.”

Renewable Energy Industry Meets Challenges Head On

Thursday, October 27th, 2011

The renewable energy industry is facing serious challenges from competition subsidized by foreign governments and restrictive regulations on the home front.  This was the consensus at the recent Solar Exchange East 2011, attended by academics, solar entrepreneurs, engineers, investors, supporters and government officials at the McKimmon Center at North Carolina State University in Raleigh.

Larry Shirley, director of the Green Economy program at the North Carolina Department of Commerce’s Energy Division, said that “Policies and incentives are the building blocks” for the solar industry.  Participants generally called for an end to government preference for fossil fuels, while critics believe the traditional means of letting private investors and the market dictate the industry’s direction is the optimal policy.

“Subsidies are basically a waste of taxpayers’ money, a form of corporate welfare,” said Roy Cordato, the John Locke Foundation’s vice president for research and resident scholar and one of the critics.  “These (renewable energy ventures) are grossly inefficient.  If they weren’t, they wouldn’t need government subsidies.”

“This is a robust environment,” said Rick Myers, director of the Solar Vertical Market Management program for Siemens.  “The U.S. solar market grew 67 percent, from $3.6 billion in 2009 to $6 billion in 2010.  Solar electric installation In 2010 totaled 956 megawatts.  There’s no doubt the U.S. government needs to get more involved in this effort from a policy standpoint.  The solar panels are 50 percent of the cost for installation and these prices are going way down.  The fact of the matter is the competition is extremely difficult in that area.  It’s coming from the Pacific Rim and China.”

In a related move that boosts renewable energy, a U.S. Treasury Department grant program that pays for up to 30 percent of a solar project’s costs would add 37,394 jobs to the economy in 2012 has been extended for one year, according to the Solar Energy Industries Association (SEIA).  The program, part of the 2009 economic stimulus package, was due to expire at the end of 2011 after an initial one-year extension was passed by Congress last December.  A second extension will boost solar jobs by 12 percent as developers increase installations by 2,000 megawatts, or enough for about 400,000 homes.  More than 100,000 Americans currently work in the solar industry, double the number in 2009, said Rhone Resch, SEIA’s chief executive officer.  “Much of the jobs and industry growth has come out of that program,” Resch said.  “The last thing the government should do in a fragile economy is eliminate a tax break that creates jobs.”

With the grant program, developers can obtain the equivalent amount in cash and write off assets more quickly.  The solar industry has received more money from the grant program than any other renewable energy sectors with the sole exception of wind.  “The (program) has been the most effective policy in driving economic and job growth in the past two years,” Resch said.  “As we continue to slog through a sluggish economy, the tax equity market remains in a much smaller capacity than where it was in 2007.”

Writing for Renewable Energy World.com, Elisa Wood says that “We hear a lot about the job-building benefits of renewable energy when it draws manufacturers and developers to local communities.  Less talked about are those who arrive well before the shovels, steel, factories and jobs.  These are the green-energy entrepreneurs – the creative thinkers and risk takers responsible for the rise of clean energy ventures over the last decade.  Others entering the industry are veterans of energy, finance, agriculture, telecommunications, high tech, science, transportation, construction, nanotechnology and commerce, all drawn by enormous opportunity, as the largest economies in the world spend an expected $2.3 trillion over the next decade to revamp industrial-age energy apparatus into cutting-edge technology.  Green energy entrepreneurs emerge from throughout North America, Europe and Asia, but they tend to congregate in high-tech regions such as Silicon Valley, an area of California becoming as much about energy as it is the internet.  ‘You can’t throw a softball around here without hitting another solar company,’ says Dan Shugar, one of the solar industry’s early pioneers and now chief operating officer of Solaria, a Fremont, CA-based company that makes silicon photovoltaic products.”

Is the Minnesota Forest Fire a Symptom of Climate Change?

Monday, September 19th, 2011

An August 18 lightning strike in a northern Minnesota forest after an unusually hot summer started a month-long fire that brought a pall of smoke to Chicago nearly a month after the blaze started.  Driven by northwest winds, the fire in the 1.1 million acre Boundary Waters Canoe Area Wilderness that straddles the Canadian border grew from about 11,000 acres to more than 100,000, said Doug Anderson, a spokesman for the firefighting effort.

The Pagami Creek fire jumped about 16 miles east in a single day, “unprecedented for northern Minnesota,” said Lisa Radosevich-Craig, a firefighting spokeswoman.  The conflagration is in an area popular with canoeists and campers deep within the three million-acre Superior National Forest, approximately 80 miles north of Duluth.  According to Radosevich-Craig, the fire was spread by near-drought conditions that had already prompted the Forest Service to close some parts of the reserve and limit campfires in others.  “Typically more than an inch of rain would have fallen in this area during this time but didn’t,” Radosevich-Craig said.  “Where the winds are coming from and the strength of the winds is unprecedented.”  The fire has burned at least 160 square miles at the Boundary Waters Canoe Area Wilderness, making it one of Minnesota’s largest on record.

The smoke was heavy enough in the Chicago area – which is 600 miles to the south — that some people complained about burning eyes and breathing problems, the National Weather Service said.  No one has been injured by the fire and no buildings have been destroyed.  “Nobody would have guessed it would be doubling and quadrupling in size,” said Jean Bergerson, a spokeswoman for the Minnesota Interagency Fire Center.

“Sometimes it’s like snow falling, there’s so much ash coming down.  And the smoke is so thick it hurts your eyes and throat.  But other times the wind switches and you can’t tell there’s a fire at all. It’s kind of odd,” said Sue Butler, owner of the Trestle Inn saloon on Crooked Lake.  The forest fire is the largest in Minnesota since 1918, surpassing 2007’s Ham Lake fire, which burned about 38,000 acres in Minnesota and another 38,000 in Ontario while also burning 163 buildings. 

“But the colder temperatures should really help.  It’s a lot harder for fire to spread when it’s in the 50s than when it’s in the 80s,” said Doug Anderson, a spokesman for the inter-agency team battling the blaze.  “People (fire officials) were pretty surprised when they saw that 100,000-acre number go up on the board.  But I think there’s some optimism out there now.”  Fires in wilderness areas typically are allowed to run their course because they renew the forest naturally.  That was the initial policy with this fire as well, but Superior National Forest officials began an all-out assault to prevent the fire from spreading.  Those efforts came too late, and officials say they didn’t have enough firefighters or aircraft to stop the fire from growing significantly.

In terms of the haze that has blanketed the Chicago area, “The smoke is a big problem, added to the impact that mold count is higher, highest number we’ve had all year. The mold makes the smoke worse, and the smoke makes the mold worse,” said Dr. Joseph Leija, of Gottlieb Memorial Hospital in Melrose Park, IL.

The fact that Minnesota is having its biggest forest fire in nearly a century naturally leads to the subject of global warming’s role in the blaze.  Wausau, WI-based WAOW.com’s “Weather You Like It or Not” column notes that “According to the National Oceanic and Atmospheric Administration (NOAA) and the National Climatic Data Center, the meteorological summer 2011 (June – August) was the second warmest in recorded history.  The average temperature across the U.S was 74.5 degrees which is 2.4 degrees above normal.  The hottest summer ever was that of 1936 with an average temperature of 74.6 degrees.  However the states of New Mexico, Oklahoma, Texas, and Louisiana did have their hottest summer on record in 2011.  Of course they also had exceptional drought.  Their number of days with 100 degrees or higher was off the charts.  Some areas had over 70 days of such heat.”

Global warming and years of outdated fire-prevention strategies are setting the stage for massive “mega-fires” that scar communities’ homes and pocketbooks.  Early findings from the United Nations’ Food and Agriculture Organization (FAO) trace the circumstances around eight mega-fires across the world in an effort to find clues on how best to avoid them and minimize potential damage.  These fires are defined more by their impact on people and the environment than by their specific size.  “Mega-fire is more of a concept than a construct,” said Robert Keane, a research ecologist at the U.S. Forest Service’s Missoula Fire Sciences Laboratory who was not involved with the report.  “What I interpret (mega-fire) to mean is not only is it large, but it affects a lot of people,” he said.  In the United States, just one or two percent of all wildfires become large incidents, but they engulf about 85 percent of total suppression-related costs and total more than 95 percent of the total acres burned, the report notes, citing earlier work.  “Among all wildfires, mega-fires are the most costly, the most destructive and the most damaging. Against the backdrop of global warming, their onset may be signaling that many conventional wildfire protection strategies are ‘running out of road.’” 

“The growing number of large wildfires and the increasing incidence of mega-fires — along with climate change projections for hotter and drier fire seasons — lend urgency to this issue,” according to the report.

Goodnight, Irene, Goodnight

Wednesday, September 7th, 2011

As Hurricane Irene literally tore up the nation’s East Coast, leaving 42 people dead in 12 states in its wake, the question naturally arises about global warming’s role in the disaster.  In a year when spring tornadoes wreaked havoc on towns like Tuscaloosa, AL and Joplin, MO, and with the Federal Emergency Management Administration’s (FEMA) budget stretched to its limit, the clean-up after Irene is almost impossible to imagine.

Estimates of the financial damage vary widely, but Peter Morici, an economist at the Smith School of Business at the University of Maryland, says that the direct costs are likely to be $20 billion, primarily in the Northeast.  Lost economic activity caused by closed restaurants and shops could add an additional $20 billion to the losses, he said. 

 Irene’s effects were particularly savage in parts of New England, as flooding and widespread power failures continued to impact thousands of people.  “I think this is going to end up being a bigger event than people think it is,” according to Connecticut Governor Dan Malloy.  “All of this is massive in scope. What the final dollar amount is, I don’t know.”  

 In southern Vermont, which was especially hard hit, the National Guard airlifted food, water and other supplies to people stranded in 13 communities cut off by floods.  “I think it’s probably a very scary thing to not know when you can get out of town and to have a water system that’s not working and a general store that has run out of bottled water,” Mark Bosma, a spokesman for the Vermont Office of Emergency Management, said.  “People are extremely nervous about being isolated.”  

Although Irene’s floodwaters were gradually receding in parts of Vermont, the governor warned that further flooding and loss of life are likely ahead for the small, rural state.  “It’s just devastating,” Governor Peter Shumlin said.  “Whole communities under water, businesses, homes, obviously roads and bridges, rail transportation infrastructure.  We’ve lost farmers’ crops,” he said.  “We’re tough folks up here but Irene…really hit us hard.” 

 Irene could prove to be one of the 10 costliest calamities in United States’ history; analysts believe that a significant amount of the damage might not be covered by insurance because it was caused by flooding and not by winds, which typically is excluded from many standard policies.  

 While insurers have typically covered roughly 50 percent of the total losses in past storms, they might end up covering less than 40 percent of the costs associated with Hurricane Irene, according to an analysis by the Kinetic Analysis Corporation.  That is in part because of the sheer amount of damage caused by flooding, and it is not known how many owners of damaged homes have flood insurance.  Another reason is the fact that deductibles have risen precipitously in coastal areas recently, requiring some homeowners to cover $4,000 worth of damages or more before insurers pick up the loss.  

 “This could make it harder for many stricken homeowners to rebuild, and could dampen any short-term boost to the construction industry that typically accompanies major storms, Jan Vermeiren, the chief executive of Kinetic Analysis, said.  Especially now that the economy is tight, and people don’t have money sitting around, local governments are broke, and maybe people can’t even get loans from the banks.”  

 Writing for Democracy Now, environmental activist Bill McKibben of 350.org,  says that “Hurricane Irene received a massive amount media coverage, but television reports made little or no reference to the role global warming played in the storm.  We’ve had not only this extraordinary flooding, but on the same day that Hurricane Irene was coming down, Houston set its all-time temperature record, 109 degrees.  We’re in a new situation.” 

In an opinion piece for the Daily Illini, Jason Febrey, writes that “Of course, climate change did not ‘cause’ Hurricane Irene in the strictest sense.  Hurricanes have been ravaging coastal areas since the dawn of time, mostly due to moist tropical air, the spin of the Earth and differential pressure fronts.  But there is no denying that climate change was a contributing factor to Irene’s severity.  Hurricanes normally lose their strength long before they approach Virginia, where ocean temperatures are not warm enough to sustain hurricane-force winds.  This year, however, has been one of the warmest on record with ocean surface temperatures of 2.6 degrees Fahrenheit above historical averages — enough to sustain a hurricane all the way up to the New England states.  Record temperatures, coupled with rising sea levels and growing amounts of moisture and energy trapped in our atmosphere, are all adding fuel to the destructive potential of natural disasters like Hurricane Irene.  Now that the worst of Irene has passed, we all ought to be grateful that damage wasn’t as terrible as some models predicted.  But we can’t rely on luck or the whims of nature forever.  How long will it be before the hurricanes of tomorrow, strengthened by warmer waters, begin to batter their way even further up the East Coast?  How long before New York turns into New Venice?  Contemplating these possibilities is a sobering exercise.”

A recent editorial written before Irene hit the East Coast in the Newark Star-Ledger  raises some interesting points about climate change.  “We can now add Hurricane Irene among the symptoms that scientists warned we’d experience as global warming occurs.  Wind of up to 100 mph, predicted to lash the East Coast.  Ocean waves as high as 12 feet.  That’s in line with what scientists have said, that hurricanes would become more severe as ocean temperatures rise.  Yet there’s another growing trend on climate change, and that’s denial.  Polls show that while most Americans believe climate change is occurring, most Republicans do not.  Climate complacency is at an all-time high, thanks to those political winds.  How big a disaster will it take to push our leaders back to scientific fact?”

President Obama Proposes Significant Increase in CAFE Standards

Tuesday, August 16th, 2011

President Barack Obama and the nation’s predominant automakers have agreed to increase new vehicles’ fuel mileage.  The major way to accomplish this is to reduce the size of vehicles.  By 2025, the Corporate Average Fuel Economy (CAFE) must be 55.4 mpg for cars.  That’s up from the 2009 Obama mandate of 35.5 mpg by 2016.  The CAFE standard for 2011 is 30.2 mpg, with light trucks having slightly less burdensome standards.

The Obama administration says the new standards will save drivers $8,200 in fuel over the life of a car.  Between now and 2015, Americans will save $1.7 trillion on fuel costs, eliminate six billion metric tons of carbon dioxide pollution and use 12 billion fewer barrels of oil.  Environmentalists applauded the new standards.  According to President Obama, “This agreement on fuel standards represents the single most important step we’ve ever taken as a nation to reduce our dependence on foreign oil.”  Joining the president at the announcement were executives of Detroit’s Big Three automakers: GM, Chrysler and Ford.  GM and Chrysler were bailed out of insolvency by the Obama administration with taxpayer money.  The government still owns 27 percent of GM; the United Auto Workers, an ally of the Obama administration and which supports the revised CAFE standards, owns 46.5 percent of Chrysler.

The tiered standards are expected to yield approximately $50 billion in net benefits over the life of model year 2014 to 2018 vehicles.  Additionally, it will result in significant long-terms savings for vehicle owners and operators.  President Obama, the U.S. Department of Transportation (DOT) and the Environmental Protection Agency (EPA) worked closely with truck and engine manufacturers, fleet owners, the State of California, and environmental groups – among them, Navistar, Volvo, Chrysler, and Con-way – to garner support for the new standards.  “While we were working to improve the efficiency of cars and light-duty trucks, something interesting happened,” said President Obama.  “We started getting letters asking that we do the same for medium and heavy-duty trucks.  They were from the people who build, buy, and drive these trucks.  And today, I’m proud to have the support of these companies as we announce the first-ever national policy to increase fuel efficiency and decrease greenhouse gas pollution from medium-and heavy-duty trucks.”

Waste Management CEO David Steiner said the rules will help his company meet a  goal of reducing emissions 15 percent by 2020.  The company will save 350 million gallons of fuel over the life of their vehicles.  FedEx CEO Fred Smith said that commercial vehicles account for 20 percent of all transportation emissions.  “Today’s progress is a win for the transportation industry, for the environment and for all Americans as we seek to decrease U.S. dependency on oil,” Smith said.

According to the White House,  the revised heavy-truck rules will cost owners as much as $8 billion in additional technology, but “will save American businesses that operate and own commercial vehicles approximately $50 billion in fuel costs over the life of the program.”  The majority of fleet operators, according to the EPA, are likely to recover their up-front costs within a year or two.  Under the new program, heavy-duty vehicles are divided into three major categories: combination tractors (semi-trucks), heavy-duty pickup trucks and vans, and what is referred to as “vocational” or special-purpose vehicles such as transit buses and garbage trucks.  More specific targets within each of these categories are based on each vehicle’s design and purpose.

American Trucking Association (ATA) president & CEO Bill Graves said the new regulations are “welcome news to us in the trucking industry.  Our members have been pushing for the setting of fuel efficiency standards for some time and today marks the culmination of those efforts.”  He said that in 2007, the ATA endorsed a six-point sustainability program that included a proposal to set “technologically feasible” efficiency standards.

The new rules do not mean that President Obama has given up on his backing of electric vehicles.  Writing on the Climate Spectator website, Jessie Giles says that “While there has been some suggestion that Barack Obama’s new measure to double fuel economy targets for cars in the U.S. might be bad news for electric cars, at Better Place our assessment is that this will in fact be important for increasing the adoption of zero-emission vehicles.  The agreement to increase the CAFE standards is good news, not just in terms of taking steps to stretch our limited oil resources further and helping to reduce our carbon emissions.  Critically, it will also help to increase the adoption of zero-emissions vehicles such as electric cars.  Now, the twist: manufacturers must meet the CAFE standards on a sales-weighted basis – that is, the average fuel economy of all the cars sold by that particular car company.  What’s the easiest way of achieving the new standards on a sales-weighted basis?  It’s by increasing the proportion of electric cars in the manufacturer’s sales mix. It’s far easier to increase this proportion of electric cars than it is to make improvements in the current fuel consumption of every single car in the rest of the portfolio, where years of product development have produced incremental, but relatively minor improvements.”

Temperatures Rising in America’s Freshwater Lakes

Wednesday, August 10th, 2011

The waters of the Great Lakes are warmer than usual this year, prompting scientists to worry that this may not be a good thing.  All five Great Lakes have been at or near record-high temperatures compared with the 30 years when such measurements have been taken.  The bad news is that there’s still a month remaining before the lakes typically reach their warmest temperatures.  Jay Austin, a physics professor at the Large Lakes Observatory in Duluth, MN, says the water is warmer because last winter there was little or no ice cover to reflect sunlight.   Scientists are unsure if it’s a blip or the new normal.  A warmer Lake Superior might be a plus for the tourism industry, but it might be bad for fishing, wildlife habitat and water levels.

“Swimmers are enjoying it,” said Al Oleksuik, who lives near the Welland River in Chippewa.  “I notice a difference here.  (The water is 24 C). It usually doesn’t hit that until mid-August. I have a feeling we’re headed towards (26 C), which is extremely warm.”  Austin said the lake is 5 to 7 C warmer than it usually is in mid-July, while the Great Lakes in general are running 2 to 7 C warmer.  “It’s going to set records, or come close, depending on where you are,” he said.

Writing in Chimes, a publication of Grand Rapids-based Calvin College, Geneva Langeland says that “Lake Michigan is warming up?  Swimmers who brave the lake’s often frigid waters might beg to differ.  But Lake Michigan’s waves aren’t alone in their slight temperature uptick; NASA satellite data suggest that lake temperatures worldwide have risen in the last 25 years, most likely as a result of global climate change.  Phillip Schneider and Simon Hook, researchers at NASA’s Jet Propulsion Laboratory in California, departed from the typical strategy of measuring global warming trends by gauging air temperatures near Earth’s surface.  Instead, the study, published in the 2010 issue of Geophysical Research Letters, used infrared satellite imagery to track changing surface temperatures in 167 large lakes splashed across the globe — including our very own Great Lakes.  The satellite data suggest that, over the past 25 years, water temperatures in large lakes have risen between .81 and 1.8 degrees Fahrenheit per decade.  These shifting temperatures varied widely among continents and hemispheres.”

According to Langeland, “Schneider and Hook noted the greatest change in northern Europe; in general, the loftier latitudes of the Northern Hemisphere consistently reported the largest temperature upticks.  The Great Lakes land squarely in that northern region.  Huron, Superior, Michigan, Erie and Ontario together comprise the world’s largest freshwater lake system.  It should come as no surprise that the ‘Big Five’ were valuable players in this study.  In fact, the Great Lakes host nine temperature-gauging buoys that were vital in verifying NASA’s satellite temperature readings.  As Schneider said, ‘The results have implications for lake ecosystems, which can be adversely affected by even small water temperature changes.’  A degree or two might be imperceptible to us, but this tiny change can have surprising repercussions.  Every organism thrives within a particular temperature range.  Altering a habitat’s air and water temperatures even slightly will kill off some creatures while allowing others to unexpectedly thrive.”

Lakes in the American West are experiencing similarly increasing temperatures.  Warming that meets statistical significance was found in Lake Tahoe along the California-Nevada border; Pyramid Lake in Nevada; and the Great Salt Lake in Utah, which were warming at a rate of more than one degree Fahrenheit per decade.  “One of the things we want to do in the future is compare these results with what the climate models predict in the region,” Hook said.  “Measuring a model’s performance in replicating changes of the recent past gives scientists a way to test the accuracy of the models being used to project future conditions.”

“Our analysis provides a new, independent data source for assessing the impact of climate change over land around the world,” Schneider said. “The results have implications for lake ecosystems, which can be adversely affected by even small water temperature changes.”

New Car Fuel-Efficiency Labels Mandated by EPA, DOT

Wednesday, August 3rd, 2011

The Environmental Protection Agency and Department of Transportation (DOT) have directed that cars and light trucks carry labels comparing estimated five-year fuel costs with those of the average new vehicle following industry opposition to adding fuel-economy letter grades to the window stickers.  The labels, which will include yearly fuel-cost estimates, must be affixed to passenger cars and trucks starting with model year 2013.  The new stickers will rate vehicles on a scale of one to 10 for smog and greenhouse-gas emissions.  “These new window stickers are a win-win” for car buyers and the auto industry, Transportation Secretary Ray LaHood said.  “They’ll help consumers make informed choices to save at the pump.”

Plug-in hybrids and electric vehicles must carry labels that specify how far a car can drive on electric power when charged.  The government decided to scrap plans for labels with letter grades after automakers, dealers and Congress said that consumers may avoid vehicles labeled with lower rankings.  Regulators abandoned the letter-grade proposal after being criticized by automakers and consumer tests indicating that some found the plan confusing, according to EPA Administrator Lisa Jackson.  “About half the people didn’t think the letter grade gave them all the information they needed,” Jackson said.  “And there was confusion that the letter grade was about the whole car.”

The labels will be quite detailed.  The estimated annual fuel cost is there, as are the standard miles-per-gallon figures for city and highway driving.  New features include the amount of fuel or electricity the vehicle will require to drive 100 miles, as well as the expected savings or cost of fuel over the next five years.  The miles-per-gallon range for same-class vehicles will be featured on the decals, as well as the highest fuel economy.  “The new labels…are the most dramatic overhaul to fuel economy labels since the program began more than 30 years ago,”  the DOT said.

The labels have some new features,  including a QR Code that allows smart phones users to access online information about how various models compare on fuel economy.  Consumers can enter information about their particular commutes and driving habits to get a more exact estimate of fuel costs.  The rule also finalizes new labels for electric vehicles and plug-in hybrids to convert the use of electricity to a miles-per-gallon equivalent — and to allow users to compare charging costs to gasoline use.  In 2010, the EPA approved interim labels for the electric Nissan Leaf and extended range electric Chevrolet Volt, which it categorizes as plug-in hybrids.

The Alliance of Automobile Manufacturers – the trade association representing Detroit’s Big Three automakers, Toyota and seven other automakers, praised the move and said the move complements labels between the federal government and California.  “Today’s announcement by EPA and DOT is a victory for consumers.  The average car buyer is a savvy shopper who gathers much information prior to buying a car, so the decision to go with informative MPG labels fits consumer needs well.  This label provides clear, visible data on fuel economy in a format consumers are already familiar with,” the group said.

Not everyone is happy with the move.  Dan Becker, director of the Safe Climate Campaign, said “The Obama administration caved to auto industry pressure and pulled the plug on a key consumer education proposal intended to help us determine which cars are cleanest.  This decision denies consumers clear information to help them make educated choices.”

The EPA created the new labels with the Transportation Department as part of rules adopted in 2010 requiring a 42 percent increase in average CAFE efficiency standards to 35.5 miles per gallon for 2012 – 2016 vehicles.  The agencies plan to require that 2017 – 2025 cars and trucks push efficiency goals to 60 mpg, a target automakers would likely resist.  Automakers, who supported the new labels, are retooling their production lines to meet government and consumer demands that they offer greater efficiency and cut pollution.

It’s HOT Out There!

Tuesday, July 26th, 2011

A severe heat wave that has kept a tight grip on the Midwest and Eastern United States that has resulted in the deaths of at least 20 people  is perceived by many as a sign of the impact of global warming.  Excessive heat watches, warnings and heat advisories were in effect in more than 30 states, in what the weather service described as “a large portion of the central U.S. and Ohio River Valley, as well as portions of the mid-Atlantic and northeastern states.  Temperatures will feel like 100 to 110 degrees or higher during the afternoon hours.”

The heat wave has brought heat index values — which measure how hot it feels — to as high as 131.  Heat indices reached 129 in Newton, IA; 121 in Taylorville, IL; 122 in Gwinner, ND, and 123 in Hutchinson, MN.  Minneapolis recorded its highest dew point ever, 82 degrees.  The dew point measures atmospheric moisture.

“This is completely out of whack for the Upper Midwest,” said Chris Vaccaro, a spokesman for the National Weather Service.  The heat wave toppled existing peak records for electricity usage.  Xcel Energy, which serves 1.64 million customers in North Dakota, South Dakota, Wisconsin and Minnesota, broke a demand record on Monday with 9,504 megawatts of power used, according to Tom Hoen, a company spokesman.  The old record set in August 2010 was 9,100 megawatts.  Utility companies in Iowa reported record usage.

In Chicago, the National Weather Service is warning that the heat wave could be the most intense since July 1999, with highs flirting with the record of 101 degrees set 31 years ago.  In the downtown area, which the weather service characterizes as an “urban heat island,” the index is likely to remain above 100 degrees late into the evening and probably will not fall below 90 all night.  More than a dozen heat-related deaths have been reported in the Midwest.

A “combination of very hot temperatures and high humidity will create dangerous heat indices over the central US”, said the National Oceanic and Atmospheric Administration (NOAA) The National Weather Service said a stagnant air mass on the central plains is the cause of the extended heat wave.  NOAA data affirm that temperatures have risen across the United States by roughly 1.5° F over the past 30 years.

This naturally leads to the subject of global warming.  According to Public Radio International’s “The Takeaway”,  Chicago’s 50-year forecast: lethal and extreme weather, a termite invasion and a 1 ½ foot drop in Lake Michigan’s depth.”

According to Aaron Durnbaugh, the deputy commissioner of Chicago’s Department of Environment, the forecast is based on fact, not fiction.  “We worked closely with the best scientists we could find to put forward our forecast, both in a best-cast and worst-case scenario — looking towards the middle of the century and 2100, the end of the century — and identifying different impacts related to precipitation and temperature, and then a follow on impact from those changes.”

Chicago’s city planners have a plan to redesign the city to accommodate the 50-year forecast.  The plan, according to an article in the New York Times, includes everything from what types of trees to plant, to more permeable roads and water-storage tanks.  The city is preparing for “sun” days: “We’re expecting many more days above 90 or 95 degrees, with heat spiking potentially to 117 degrees in the summer,” Durnbaugh said.  “And we have a history, unfortunately, of heat-related disasters in Chicago.  Cities adapt or they go away.  Climate change is happening in both real and dramatic ways, but also in slow, pervasive ways.  We can handle it, but we do need to acknowledge it. We are on a 50-year cycle, but we need to get going.”

According to a study published in the journal Environmental Health Perspectives, global climate change could, by 2081 to 2100, drive that average number of yearly heat wave-related deaths to between 166 and 2,217.  “Our study looks to quantify the impact of increased heat waves on human mortality,” said lead author Roger Peng, associate professor of biostatistics at Johns Hopkins University. “For a major U.S. city like Chicago, the impact will likely be profound and potentially devastating.  It’s very difficult to make predictions, but given what we know now — absent any form of adaptation or mitigation — our study shows that climate change will exacerbate the health impact of heat waves across a range of plausible future scenarios,” Peng concluded.

Google Goes Green

Wednesday, July 6th, 2011

Google and SolarCity,  a rooftop solar-panel company announced a $280 million investment deal,  the largest such deal for home-based solar power systems in the United States.  The investment gives San Mateo, CA-based SolarCity the funding to build and lease solar power systems to as many as 7,000 to 9,000 homeowners in the 10 states in which it operates.

Established in 2006, SolarCity currently has 15,000 solar projects around the nation completed or under way.  Customers who want to have the firm’s solar system installed at their homes can pay for it up front; however, the majority let SolarCity retain ownership of the equipment and rent back the use of it through monthly solar lease payments.  By financing SolarCity, Google will recoup its investment through those lease payments.  “We hope to be seen as a model,”said Rick Needham, Google’s director of green business operations.  Needham didn’t discuss the deal’s terms, but said “these investments are designed to earn us a good return on our capital.”

“It allows us to put our capital to work in a way that is very important to the founders and to Google, and we found a good business model to support,” said Google’s Joel Conkling.  Google CEO Larry Page wants the firm’s operations to eventually produce no-net greenhouse gas emissions.  To achieve this, Google has invested in wind farms in North Dakota, California and Oregon, solar projects in California and Germany, and the beginning stages of a transmission system off the East coast to encourage the construction of offshore wind farms.  The SolarCity deal is Google’s seventh green energy investment, totaling more than $680 million.

Typically, a rooftop solar system costs $25,000 to $30,000, which is beyond the means of many homeowners.  Instead, solar providers like SolarCity, SunRun and Sungevity pay for the system with money borrowed from a bank or a specially-designed fund similar to the one that Google has created.  The resident then pays a set rate for the power generated which is lower than or approximately the same as local electricity.  Typically, s 5-kilowatt system will generate 7,000 kilowatt-hours of power annually, or about 60 percent of the household’s annual use.  The homeowner buys remaining electric power from the local utility, typically enjoys lower overall power bills and has some protection against potentially higher traditional electricity prices.  Electricity prices have not risen in recent months, but are expected to rise in coming years as the cost of increasingly stringent clean-air regulations are passed on to customers.  If the solar company is to make money and the homeowner save money, there must be a combination of high local electric rates, state and local subsidies, as well as low installation costs.  Then there is the matter of sunshine.  A house with solar panels should have a roof that faces South that is not shaded by trees or other buildings.

You have full flexibility in what you want to pay on a monthly basis,” said SolarCity CEO Lyndon Rive, who pointed out that homeowners are charged only for the electricity the company’s solar panels generate at or below market rates.  If the panels produce more power than the home uses, the consumer gets a credit.  “It’s actually a win-win,” Rive said.  “This industry is going gangbusters despite the economy,” said Danny Kennedy, founder of Oakland-based Sungevity.  According to Kennedy, the lease option his company started offering in March 2010 has pushed sales “through the roof.”  He expects to complete 30,000 leases in 2011, up from 10,000 in 2010.

California and Colorado accounted for more than a third of the residential solar market leases in the 1st quarter of 2011, according to a report from the Solar Energy Industries Association (SEIA).  The growth reflects that of the overall solar panel market, which expanded at an average annual rate of 69 percent since 2000, including 100 percent in 2010, according to SEIA, which expects the market to double this year.

Google has chosen to invest in clean energy projects because of the potential returns and the potential to impact the industry.   “We hope that Google’s leadership in the space will encourage other corporate investors,” Rive said.  There definitely is room for other investors to get involved: Fewer than 0.1 percent of American homes currently have rooftop solar panels, but that number is expected to grow to 2.4 percent by 2020, according to Bloomberg New Energy Finance. It’s highly likely that Google-financed companies like SolarCity will have a role in that growth.

The SolarCity project is not Google’s first venture into the clean energy market.  The firm has invested $168 million in California’s Ivanpah solar farm and another $100 million in the world’s biggest wind farm.  That is the $2 billion Shepherds Flat project,  near Arlington, OR, that will stretch over 77 square kilometers of north-central Oregon and generate enough energy for 235,000 homes.  The project, which will go into operation in 2012, is being developed by Caithness Energy.
