“Warming has led to changes in climate extremes such as heat waves, record high temperatures and, in many regions, heavy precipitation since 1950, the U.N. climate panel warned in a report Wednesday.
“It is very likely that there has been an overall decrease in the number of cold days and nights, and an overall increase in the number of warm days and nights, at the global scale,” the scientists wrote.
“Some populations are already living on the edge of disaster, given the projected increases in the magnitude or frequency of some extreme events in many regions, the report stated.”
