Scientific American has an informative new article, "Seven Answers to Climate Contrarian Nonsense," breaking down some of the most prevalent misguided attacks from opponents of clean energy legislation.  In the article, author John Rennie responds to claims about the "hockey stick," the scientific consensus about the dangers of climate change, and more.  Here's one particularly compelling passage:

Claim 5: Climatologists conspire to hide the truth about global warming by locking away their data. Their so-called "consensus" on global warming is scientifically irrelevant because science isn't settled by popularity.

It is virtually impossible to disprove accusations of giant global conspiracies to those already convinced of them (can anyone prove that the Freemasons and the Roswell aliens aren't involved, too?). Let it therefore be noted that the magnitude of this hypothetical conspiracy would need to encompass many thousands of uncontroversial publications and respected scientists from around the world, . ">stretching back through Arrhenius and Tyndall for almost 150 years. (See this feature on “Carbon Dioxide and Climate,” by Gilbert N. Plass, from Scientific American in July 1959.) It is also one so powerful that it has co-opted the official positions of dozens of scientific organizations including the U.S. National Academy of Sciences, the Royal Society, the American Association for the Advancement of Science, the American Geophysical Union, the American Institute of Physics and the American Meteorological Society.

If there were a massive conspiracy to defraud the world on climate (and to what end?), surely the thousands of e-mails and other files stolen from the University of East Anglia’s Climatic Research Unit and distributed by hackers on November 20 would bear proof of it. So far, however, none has emerged. Most of the few statements that critics claim as evidence of malfeasance seem to have more innocent explanations that make sense in the context of scientists conversing privately and informally. It is deplorable if any of the scientists involved did prove to manipulate data dishonestly or thwart Freedom of Information requests; however, it is currently unclear whether that ultimately happened. What is missing is any clear indication of a widespread attempt to falsify and coordinate findings on a scale that could hold together a global cabal or significantly distort the record on climate change.

Definitely an article worth reading and sharing.

A recent Washington Post poll finds that GOP-leaning voters support bipartisan action on energy, far more than they support bipartisan work on health care policy. 

This is consistent with all recent polling, Climate Progress writes, pointing to three recent surveys:

• Voters in Ohio, Michigan and Missouri overwhelmingly support action on clean energy and global warming
• Yet another major poll finds “broad support” for clean energy and climate bill: “Support for the plan among independents has increased slightly”
• Swing state poll finds 60% “would be more likely to vote for their senator if he or she supported the bill” and Independents support the bill 2-to-1

Jonathan Hiskes of Grist.org outlines the key findings of the just-released Copenhagen Diagnosis, "a startling update" to the IPPC work from 26 climatologists, "reporting that sea levels could rise and methane-laden arctic permafrost could melt much sooner than the panel had anticipated."

Surging greenhouse gas emissions: Global carbon dioxide emissions from fossil fuels in 2008 were nearly 40 percent higher than those in 1990. Even if global emission rates are stabilized at present-day levels, just 20 more years of emissions would give a 25 percent probability that warming exceeds 2°C, even with zero emissions after 2030. Every year of delayed action increases the chances of exceeding 2°C warming.

Recent global temperatures demonstrate human-induced warming: Over the past 25 years temperatures have increased at a rate of 0.19°C per decade, in very good agreement with predictions based on greenhouse gas increases. Even over the past ten years, despite a decrease in solar forcing, the trend continues to be one of warming. Natural, short-term fluctuations are occurring as usual, but there have been no significant changes in the underlying warming trend.

Acceleration of melting of ice-sheets, glaciers and ice-caps: A wide array of satellite and ice measurements now demonstrate beyond doubt that both the Greenland and Antarctic ice-sheets are losing mass at an increasing rate. Melting of glaciers and ice-caps in other parts of the world has also accelerated since 1990.

Rapid Arctic sea-ice decline: Summer-time melting of Arctic sea-ice has accelerated far beyond the expectations of climate models. The area of sea-ice melt during 2007-2009 was about 40 percent greater than the average prediction from IPCC AR4 climate models.Read more
