Global Science Report is a feature from the Center for the Study of Science, where we highlight one or two important new items in the scientific literature or the popular media. For broader and more technical perspectives, consult our monthly “Current Wisdom.”
The main idea, as it is portrayed, driving the Obama administration’s pursuit of carbon dioxide regulations is that climate change is leading to all manner of bad things. Pointing to concrete example of bad things that have resulted from human greenhouse gas emissions, however, is much more challenging than just saying it is the case. In fact, for most climate/weather events and their resulting effect, the bulk of the science contradicts the administration’s contentions.
An especially egregious example concerns heat-related mortality. It is true that extreme heat can lead to excess mortality. It is also true that global warming should lead to more heat waves. However, it is NOT true that global warming will lead to more heat-related mortality—the logic forwarded by the administration. Frequent readers of this blog are well aware of this.
However, as not everyone (to his or her detriment) is a frequent reader of this blog, we presented our findings on climate change and heat-related mortality to the audience at a science policy conference held by the American Geophysical Union (AGU) this week. Our conclusions were:
