A new report from the government finds that the time to worry about climate change is now (or, really, years ago), because it is here in full effect already.
This morning, the Obama Administration released a major report showing how climate change is already upon us. From agriculture to human health, global warming is already having wide impacts, all the evidence shows. And, of course, what’s happened so far is just a prelude. It’s going to get much worse unless we stop exacerbating the problem by putting more carbon into the atmosphere.
The third National Climate Assessment (NCA) is based on the work of 200 scientists, and is the most comprehensive study of its type to date.
