Ice, Please — Climate on the Rocks

Those who deny the reality or significance of climate change often say Arctic sea ice also shrank dramatically as recently as the 1930s, so what’s happening now is just part of a natural long-term fluctuation. But the best recent analysis, published in the top scientific journal Nature last November, says that “both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years” and that the recent decline is “consistent with [human-caused] warming.”

The science of climate change is the kind of topic that gives journalists great difficulty. As they bounce from issue to issue in our info-glutted world, they aren’t able to explore each one in depth or develop detailed expertise about a subject. So when it comes to complex scientific problems, journalists tend to cherry-pick findings and cite opinionated statement by outspoken researchers. Context and nuance are lost. And in the case of research on the links between global warming and hurricanes, context and nuance are everything.
