Mass loss of Greenland ice sheet delays climate change for millennia

What is it about?

Despite that the gradual global warming over the past centuries, , no significant disintegration of Greenland ice sheet was has been seen. This study explained why. We find that the Greenland Ice Sheet's mass response delays climate change for millennia. Since the northern hemisphere summer was cooling due to the movement in the Earth's perihelion from Northern Hemisphere summer to Southern hemisphere summer, the Greenland Ice Sheet kept growing in the past several thousands years. This growing trajectory was reversed until the late 20th century, thanks to the anthropogenic warming. This contribute to increasing the rate of global mean sea level rise.
