Brace for more warm weather through 2022

Manmade global warming and a natural surge in Earth's surface temperature will join forces to make the next five years exceptionally hot, according to a study published Tuesday.

The double whammy of climate change and so-called natural variability more than doubles the likelihood of "extreme warm events" in ocean surface waters, creating a dangerous breeding ground for hurricanes and typhoons, they reported in Nature Communications.

Earth's average surface temperature has always fluctuated. Over the last million years, it vacillated roughly every 100,000 years between ice ages and balmy periods warmer than today.

Over the last 11,000 years, those variations have become extremely modest, allowing our species to flourish.
