> It applies because the article exclusively discusses a 2 degree temperature rise. You are correct in pointing out that the headline is, at face value, incorrect. The context is that the 2 degrees C is a global average temperature increase compared to some fixed baseline. As an average it doesn't say anything about the variance. To illustrate, the average value of 4, 4, 5, 6, 6 and 1, 1, 5, 9, 9 are the same, 5. Our climate models however show that an increase in average temperature will most likely be accompanied by a fair increase in variance, meaning both much hotter and much colder weather. And it's this increase in variance that's the main issue.
