[15] Since then, a number of updated ECS distributions have been estimated, suggesting lower probabilities of
extreme global warming.
«We've got a case of
extreme global warming, the most extreme ever seen in the last 600 million years,» Wignall said.
The dead zone apparently experienced a serious case of global warming, but
the extremes this global warming reached were uncertain.
