The Northern Hemisphere has recently seen a big jump in extreme weather events. A growing body of research ties that jump to “more frequent high-amplitude (wavy) jet-stream configurations that favor persistent weather patterns” (as a new 2015 study puts it) -- linked directly to global warming.
Recent peer-reviewed studies strongly support the view that California's epic drought was made considerably worse by human-caused global warming. A new NOAA report seeking to cast doubt on that assertion omits some of the latest science and is deeply flawed, as three leading climatologists told me.
If you thought you’d noticed deluges becoming more intense, you were right. Thanks to climate change, when it rains, it pours, literally. Some 70 percent more precipitation falls in the heaviest rain events now than it did in 1958. Here's why.
