We are standing on the edge of a new world where warming is poised to accelerate at rates unseen for at least 1,000 years.
That’s the main finding of a paper published March 9 in Nature Climate Change, which looked at the rate of temperature change over 40-year periods. The new research also shows that the Arctic, North America, and Europe will be the first regions to transition to a new climate, underscoring the urgent need for adaptation planning. Historical records show temperatures have typically fluctuated up or down by about 0.2 °F per decade over the past 1,000 years. But trends over the past 40 years have been decidedly up, with warming approaching 0.4 °F per decade. That’s still within historical bounds of the past—but just barely.
Faster and faster. That's called "acceleration".
Prediction by extrapolation is chancy; extrapolating accelerating phenomena is just a fool's game.
