Reports From Four Fronts in the War on Warming

Over the last few decades, as scientists have intensified their study of the human effects on climate and of the effects of climate change on humans, a common theme has emerged: in both respects, the world is a very unequal place.

In almost every instance, the people most at risk from climate change live in countries that have contributed the least to the atmospheric buildup of carbon dioxide and other greenhouse gases linked to the recent warming of the planet.

Those most vulnerable countries also tend to be the poorest. And the countries that face the least harm — and that are best equipped to deal with the harm they do face — tend to be the richest.

To advocates of unified action to curb greenhouse gases, this growing realization is not welcome news.

“The original idea was that we were all in this together, and that was an easier idea to sell,” said Robert O. Mendelsohn, an economist at Yale. “But the research is not supporting that. We’re not in it together.”

The large, industrialized countries are more resilient partly because of geography; they are mostly in midlatitude regions with Goldilocks climates — neither too hot nor too cold.
