6 to 7 degree temperature rise in 3years!

In this article in the Guardian I came across the following paragraph:

"Britain's icy desolation ended abruptly 14,700 years ago when there was a dramatic leap in temperatures across the globe according to ice-cores found in Greenland and lake sediments in Germany. In less than three years, temperatures had soared by around 6 to 7 degrees Celsius and ice sheets began a rapid retreat throughout the world."

Which makes the predicted global warming increase of up to 3 degrees by 2100 look small beer.

Assuming the global temperature does increase by 3 degrees by 2100 we can be sure that the planet and life on it will be fine. What we're less sure about is the disruption that will happen..
