Toward a Defensible Climate Realism

Toward a Defensible Climate Realism

It’s a tough time to be an American climate realist. After all, which realism will you choose? The Beltway realism that limits U.S. commitments, and even U.S. initiatives, to those that are immediately sustainable by veto-proof congressional majorities? The internationalist realism that begins instead with the recognition that – as the recent multilateral climate talks in Bali clearly indicated – a viable global accord will necessarily require substantial rich-world financial commitments? How about a straightforward scientific realism that proceeds differently, ignoring the politics of the moment and stressing instead the physical demands of the climate system?

Climate Change Flap at the G8

Climate Change Flap at the G8

The headlines in the lead-up to the Group of Eight (G8) meeting here in Rostock have focused on the dispute over the proposed declaration on climate change. German Chancellor Angela Merkel wants the rich countries to commit to limiting global warming to two degrees centigrade. This will involve cutting greenhouse gas emissions to 50% of their 1990 levels by 2050 and increasing energy efficiency by 50% by 2020. Merkel’s proposal drew predictable opposition from George W. Bush. However, to contain further damage to his battered image, Bush called for a conference of the biggest greenhouse gas polluters to deal with global warming. This has alarmed Merkel, who wants to keep the process securely within the United Nations.

The debate in the United States on global climate change is shifting from whether to do something about the problem to what to do. The conventional wisdom focuses on “cap and trade,” also known as tradable emissions permits. The Kyoto protocol, for instance, has instituted a cap-and-trade system for greenhouse gases (GHGs).

A New Standard for Preventing Global Warming

A New Standard for Preventing Global Warming

The debate in the United States on global climate change is shifting from whether to do something about the problem to what to do.1 Prudent people do not want to risk unacceptable adverse economic impacts, even if they are extremely concerned about global climate change. On the other side, equally prudent people do not want to risk accomplishing too little. The debate is stymied, even though several bills on global warming have been introduced into Congress. “There will be no climate change legislation coming out of my committee this year,” Senator Pete Domenici (R-NM) recently announced. “Frankly, I don’t know how to write it, and I don’t think anybody does.”2
