More precisely: "It is virtually certain that increases in the frequency of warm daily temperature extremes and decreases in cold extremes will occur throughout the 21st century on a global scale."

While it’s been talked about for years, the link between severe weather and climate change is now solidified. The conversation is turning from mitigation to adaptation. Insurance companies are factoring the climate into how—and whether—they offer coverage.
