Climate change expected to hit Minn. with rising temps, moving forests | Minnesota Public Radio News
If you start looking at the numbers it just becomes pretty remarkable. Let's boil this down to a number: 36. That's the number of years since the last cooler-than-average year globally. 1976 was the last year that we were cooler than the 20th century average. So if you're 36 years old or younger, you have never lived on this planet through a cooler than average year. The 10 warmest years have all occurred since 1998. Twelve of the 14 warmest years since 2000. Every year since 2000 has been in the top 14 warmest years. Twenty in the past 25 years. And each of the past three decades has been warmer globally than the previous decades. So from the 80s to the 90s to the 2000s.
If you look at that as a natural occurrence, that's a one-in-a-billion shot. You would expect in any natural system you're going to have some above-average, below-average years. To have that many decades in a row where the climate is consistently warming, there's something else going on there.
