NY Times: Studies Say Natural Gas Has Its Own Environmental Problems

Natural gas, with its reputation as a linchpin in the effort to wean the nation off dirtier fossil fuels and reduce global warming, may not be as clean over all as its proponents say.

Even as natural gas production in the United States increases and Washington gives it a warm embrace as a crucial component of America’s energy future, two coming studies try to poke holes in the clean-and-green reputation of natural gas. They suggest that the rush to develop the nation’s vast, unconventional sources of natural gas is logistically impractical and likely to do more to heat up the planet than mining and burning coal.
The problem, the studies suggest, is that planet-warming methane, the chief component of natural gas, is escaping into the atmosphere in far larger quantities than previously thought, with as much as 7.9 percent of it puffing out from shale gas wells, intentionally vented or flared, or seeping from loose pipe fittings along gas distribution lines. This offsets natural gas’s most important advantage as an energy source: it burns cleaner than other fossil fuels and releases lower carbon dioxide emissions.
“The old dogma of natural gas being better than coal in terms of greenhouse gas emissions gets stated over and over without qualification,” said Robert Howarth, a professor of ecology and environmental biology at Cornell University and the lead author of one of the studies. Mr. Howarth said his analysis, which looked specifically at methane leakage rates in unconventional shale gas development, was among the first of its kind and that much more research was needed.

Ozone layer faces record loss over Arctic

Associated Press, 04.05.11, 04:14 AM EDT


GENEVA -- The U.N. weather agency says the depletion of the ozone layer shielding Earth from damaging ultraviolet rays has reached an unprecedented low over the Arctic this spring, because of harmful chemicals and a cold winter.
The World Meteorological Organization said Tuesday that the Earth's fragile ozone layer in the Arctic region has suffered a loss of about 40 percent from the start of winter until late March exceeding the previous seasonal loss of about 30 percent.
The Geneva-based agency blamed the loss on a buildup of ozone-eating chemicals once widely used as coolants and fire retardants in a variety of appliances and on a very cold winter in the stratosphere, the second major layer of the Earth's atmosphere.

Tsunami in Japan 3.11 First Person Footage

This is first person footage from the tsunami in Japan. I knew that a tsunami is incredibly destructive, but I guess I didn't realize how powerful 10 feet of water can be -- this is easily illustrated by entire buildings floating away towards the end of the video.

BBC: Renewable heating scheme unveiled

Subsidies for renewable heating systems in England, Scotland and Wales have been announced by the UK government.
Money will be given to those who choose technologies such as wood-chip burners instead of cheaper, but more polluting, fossil fuel heating systems.
Industry experts say the scheme is the first of its kind in the world. The government hopes it will haul the UK proportion of low-carbon heat from the current 1% towards the EU average of 10%.

House Will Pursue Efforts to Eliminate Funding for UN Climate Group

If House Republicans have their way, the U.S. may sever its fiscal support for the United Nations' climate group, reflecting the last lingering effects of the Climate-gate scandal that shook climate science and wobbled the world's confidence in the theory that man's actions are causing the planet to rapidly warm.

Wrapped into the many amendments recently passed by the House of Representatives -- a total of $60 billion in spending cuts that the president called a "nonstarter" -- was one by Republican Missouri Rep. Blaine Luetkemeyer that would prohibit $13 million in taxpayer dollars from going to the Intergovernmental Panel on Climate Change (IPCC), the group whose occasional missteps have been the source of countless confrontations among climate scientists over the past year.

New Normals on the Way

A new decade means a new set of normal temperatures and precipitation, according to the New York Times. I linked to UAH's Dr. Roy Spencer in this blog earlier in the week about the record tying satellite measured temperatures for 2010. In his report he also discussed the upcoming changes in the normals.
A typical climate normal is based on the weather pattern over a 30-year period.
The old normals were based on data from 1971-2000, according to the NYT article.

The new normals, which will be released later this year, will drop the cooler 1970's and add the 2000's, which is the warmest recorded decade in history, according to the NYT.
Based on the above, you can bet that the new normals are going to be a bit higher over a majority of regions across the world. The greatest increase in normals will likely be over the northern high latitudes, while the southern latitudes will see the least amount of change in their normal temperatures.

NY Times: Republicans Wants Courts Out of Climate

February 8, 2011, 11:13 am

Keep Courts Out of Climate Policy, G.O.P. Lawmakers Say

Three leading Republicans in Congress filed a brief with the Supreme Court late Monday asking the justices to overturn a lower court ruling that allowed several states and environmental groups to sue electric utilities over their global warming emissions.
The lawmakers – Senator James Inhofe of Oklahoma and Representatives Fred Upton of Michigan and Ed Whitfield of Kentucky – submitted a 13-page friend of the court brief in the case, American Electric Power v. Connecticut, No. 10-174. The Supreme Court will hear arguments in April in an appeal of a 2009 decision by the United States Court of Appeals for the Second Circuit, in New York, allowing a suit filed against five utilities by eight states, New York City and three land trusts to proceed.

A lower court had dismissed the suit, calling regulations of emissions a matter to be decided in the political, not legal, system.
The suit, originally brought in 2004, argued that the utilities were creating a public nuisance by burning coal and pouring heat-trapping gases into the atmosphere, adding to the problem of global warming. The states and groups that filed the case considered it an alternative to legislative or regulatory action on climate change, which was then – as now – moving at a snail’s pace.
A number of other business, labor, legal and local government groups have also filed briefs in the case, but the petition from the three Republican lawmakers is novel. The three lawmakers have all expressed skepticism about the reality of human-caused global warming, yet in their brief they say that the political system, not the courts, should deal with the problem.

The three just last week circulated draft legislation that would prevent the Environmental Protection Agency from issuing any regulations on greenhouse gases beyond those already written for vehicles. At the same time, they oppose any comprehensive legislation to deal with climate-altering gases because they say they believe the science is uncertain and the costs of reining in carbon dioxide and other emissions will be too high.
Yet in their brief they say there is no need for judicial intervention because Congress and the administration are already dealing aggressively with the matter.
In this, they take the same position as the Obama administration, which has also argued that the appeals court decision should be overturned because the administration is hard at work on the problem and does not need the courts’ help.
“E.P.A. has already begun taking actions to address carbon-dioxide emissions,” the Obama administration’s acting solicitor general, Neal Katyal, said in a brief last August. “That regulatory approach is preferable to what would result if multiple district courts — acting without the benefit of even the most basic statutory guidance — could use common-law nuisance claims to sit as arbiters of scientific and technology-related disputes and de facto regulators of power plants and other sources of pollution.”
The Republicans agree, to a point. “This case involves political and public policy matters that are being resolved by the legislative and executive branches of government,” the three Republicans wrote in their brief. “These public policy determinations are necessarily within the purview of the Congress and the executive branch, not the judicial branch, because of the complexity and significance of the environmental and economic issues that they raise.”
Mr. Inhofe, the senior Republican on the Senate Environment and Public Works Committee, is the most outspoken climate change skeptic in Congress. Mr. Upton is chairman of the House Energy and Commerce Committee; Mr. Whitfield chairs the panel’s subcommittee panel on Energy and Power. Mr. Whitfield’s committee is planning a hearing on Wednesday to grill administration officials about plans to regulate carbon dioxide emissions. Mr. Inhofe is one of the scheduled witnesses.
Their brief lists several actions, from the Clean Air Act in 1963 through recent energy legislation, that show that the political branches of government are acting on the problem of emissions. They say that the government is spending billions of dollars a year in climate change research and mitigation efforts. They note that the United States ratified the United Nations Framework Convention on Climate Change and participates actively in global climate diplomacy. They even note that in 2009 the House passed a sweeping cap and trade bill to control greenhouse gas emissions – legislation that all three of them vigorously opposed.
“No one can seriously question that the executive branch, acting through the E.P.A., the Department of State and various other departments and agencies, has aggressively employed its various statutory authorities in acting on climate change,” they write in their brief.
They go on to say that some of the recent actions by the Obama administration, including its intent to regulate greenhouse gases under the Clean Air Act, “may well exceed the authorities Congress has vested in the executive, and are at a minimum extremely misguided.”
Misguided or not, the brief continues, the issue should be debated and resolved by representatives and officials who are elected or otherwise accountable to the public.
“Climate change issues are extraordinarily complex, both because of the climate science itself and because any proposed solutions to address climate change have enormous domestic, international and economic implications,” they said.
“This case calls for determinations that are not appropriate for judicial discretion,” they add a few pages later. “As such, they raise public policy issues that necessarily should be determined by the Congress and the executive branch precisely because they are so complex and controversial.”
Joseph Mendelson, director of global warming policy at the National Wildlife Federation and a lead lawyer on the last major global warming case to come before the Supreme Court, Massachusetts v. Environmental Protection Agency, No. 05-1120, said that the argument from the three Republicans was “ironic at the least.”
“It’s rather amazing what they’ve done,” he said in an interview. “They’re trying to foreclose action by anybody.”
The Supreme Court is scheduled to hear arguments in the Connecticut case on April 19. Justice Sonia Sotomayor recused herself because she sat on the Second Circuit panel that heard the case, although she did not take part in the ruling.

Latest Cooling Not Unexpected

The latest satellite measured temperature data for the month of January has just been released and there are no real surprises.

According to Remote Sensing Systems, the average global lower tropospheric temperature anomaly for the month of January 2011 was 0.083 C above normal. This continues the short downward trend of temperature anomalies that began in the fall of 2010 in response to the strengthening La Nina.
This is not unexpected to climate scientists. La Nina's have a general cooling influence on the global temperature. Future long-term warming forecasts take into account the fluctuations of La Nina and El Nino.

The image below shows the average temperature anomalies globally during the month of January 2011 for the lower troposphere. Courtesy of RSS. Note the cold anomalies over the eastern U.S., central Pacific and eastern Asia. Still relatively warm over the far north, esp. northeast Canada.


Despite a very inactive sun, 2010 still ended up tied for the warmest year on record even with the end of the year cooling trend.

During the Fall 2007 to spring 2008 La Nina, which was similar in strength to this current La Nina, global satellite measured temperatures during 4 of the first 6 months of 2008 were actually below normal.

There is usually a several month lag in global temperature response to the onset La Nina and El Nino, so we should not be surprised that the next few months continue to run close or even below normal. Model consensus has this current La Nina peaking now with a slow weakening trend into the summer.


January 2011 satellite temperature anomaly statistics
Global (70S to 82.5 N): +0.083 C
Cont. USA: -.794 C
Arctic region: +1.800 C
The RSS global lower troposphere temperature anomaly plot below which goes back to 1979 still shows a positive decadal trend of +.163 C.

Or you could cherrypick the same graph only showing 1998 on and say that there has been no recent warming. In this case, ignore the trend line, that's the 1979-2011 trend.


The last decade was the warmest on record. I think it is safe to say that the planet is warming. Satellite and surface observations confirm it.

According to Dr. Roy Spencer, the University of Alabama at Huntsville satellite measured temperature anomaly for the lower troposphere in January 2011 was -0.009 C.
