Sentences with phrase «41kyr obliquity»

In a recent paper, paleoclimatic data shows that the tropical monsoon cycle responds very reliably to the ups and downs of Milankovitch insolation forcing on one of the shorter time scales (either 23kyr 65N forcing swings or the 41kyr obliquity cycle, I forget which), but the ice sheets and sea level and global temperature do not respond directly to those insolation forcings.

Here, for example, is normalized amplitude of the 41kyr obliquity changes compared to normalized amplitude of the 41kyr response in the LR04 stack (time goes from left to right, with the present at the far right):

And why does the 41kyr obliquity cycle dominate most of the time?
