The Climate Change Hangover

Let’s assume that the Obama administration and Congress get their act together this year and make good on their pledge of enacting meaningful climate legislation by establishing the nation’s first cap-and-trade system.

Let’s further assume, for the sake of argument, that the administration, working with its international partners, succeeds in drafting a robust successor to the Kyoto Protocol at the climate talks in Copenhagen later this year.

If we accept that the U.S. climate bill, known as the American Clean Energy and Security Act (ACES), will accomplish its goal of bringing down emission levels 80 percent below 2005 levels by 2050—which is nothing to sneeze at when you consider that a substantial fraction of policymakers (including some Democrats) vehemently oppose the measure—then the question becomes: Will it be enough to prevent the worst of climate change?

New Study on Solar Variability Is Neither New Nor a Study

Misinterpreting a new study requires there to be a new study in the first place. Though it may seem obvious, this basic truth was evidently lost on the throngs of deniers who pounced on a story about solar variability that appeared on the news aggregator ScienceDaily—on May 12, 2008.

The piece, entitled “Solar Variability: Striking a Balance with Climate Change,” makes the point that, over the course of the Earth’s history, the sun and volcanic eruptions have typically exerted the largest influence on climate change. In recent decades, however, the sun’s influence in particular has been replaced by that of anthropogenic activity—something which Robert Cahalan, a climatologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, says “has never happened before.”

Denier Conference Readies for Round Three

Among the many conservative think tanks faithfully pushing the skeptic message in Washington, D.C., few are as prominent—or, should I say, infamous—as the Heartland Institute. The “independent” research and non-profit group has the dubious distinction of having organized the first major denier-palooza, the “International Conference on Climate Change,” last year. Despite a less than stellar showing, and an even more lukewarm follow-up in March, it’s hoping that the third time will be the charm.

The likes of Senator James Inhofe, Lord Christopher Monckton and Anthony Watts will be descending on the Washington Court Hotel this week to discuss the “widespread dissent to the asserted “consensus” on the causes, consequences, and proper responses to climate change.” Its ostensible purpose will be to “expose Congressional staff and journalists to leading scientists and economists in the nation’s capital” and demonstrate that “global warming is not a crisis and that immediate action to reduce emissions is not necessary”—which it calls the emerging consensus view of (the handful of) scientists outside the IPCC.

A Question of Framing

What a difference a year can make. While the consensus on the Hill may not have grown stronger in the interim—I’m looking at you, House Republicans—the American public seems to be increasingly wising up to the idea that global warming is, in fact, a real threat and not some nefarious liberal plot to deprive it of its God-given right to pollute.

That is the principal finding of a new survey, entitled “Global Warming’s Six Americas,” that was released this past week by the Center for American Progress. The survey, which the authors describe as an “audience segmentation analysis,” splits the American public into six distinct groups based on their level of engagement with global warming: alarmed, concerned, cautious, disengaged, doubtful, and dismissive.

The authors polled 2,129 American adults in the fall of 2008 on a variety of issues related to global warming, including risk perceptions, policy preferences, and values.

The Oceans v. EPA

Out of sight, out of mind,” is a pithy saying that aptly sums up the attitude most industrialized countries have toward ocean acidification. While there has been much (justified) hand-wringing about the terrestrial impacts of climate change, policymakers have largely ignored the threats posed by acidic seas – which are considerable.

For one, ocean acidification could wipe out a significant fraction of the world’s coral reefs – perhaps even all of them – by mid-century if we don’t curb our emissions. In late 2007, 17 marine biologists co-authored a review article in Science in which they warned that, under a worst-case emissions scenario (450 – 500 ppm and a temperature increase larger than 5.4°C), all reefs could disappear, taking up to half of all marine life with them.

The OMB-EPA Kerfuffle That Wasn't

Is the White House Office of Management and Budget (OMB) deliberately trying to sabotage the EPA’s efforts to regulate carbon dioxide emissions? Is Peter Orszag, the agency’s brainy and genial director, secretly in cahoots with Republican opponents of President Obama’s climate policies?

Not quite – though that may have been your first impression upon reading the raft of articles published yesterday that breathlessly reported that an OMB memo had strongly criticized the EPA’s proposal to regulate greenhouse gases.
