Climate Denial Crock of the Week/1998 Revisited

One of the enduring myths of climate denialism is that global warming stopped sometime in the last decade. I see it in the blaring headlines of pseudoscience websites, in comments on my videos, even some of our most “distinguished” journalists have been taken in.

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 Worse Is Yet to Come

Melting ice caps. Crippling droughts. Acidifying oceans. Even to the untrained eye, the trends are becoming starkly clear: Climate change is upon us, and it’s only getting worse.

That, in essence, was the grim takeaway from a speech given by Christopher Field, the founding director of the Carnegie Institution’s Department of Global Ecology at Stanford University and a co-author of the 2007 U.N. Intergovernmental Panel on Climate Change report, at the annual meeting of the American Association for the Advancement of Science (AAAS) last week.
