If man-made greenhouse gas emissions are going to cause more droughts and storm surges on a persistent basis, why did it take so long? And why is it only a concern in the last 25 years, rather than in the 1930s, when things were really hot?
A new estimate claims it's because the natural atmosphere already contained carbon dioxide that human-induced changes were relatively small. Had these natural concentrations been lower, the effects of the emission of harmful greenhouse gases would have been felt much earlier.
