Sentences with phrase «changes in insolation driven»

Small changes in insolation driven by changes in the Earth's orbit can push the planet into or out of an ice age through the planet's «climate feedback» mechanisms.

These are thought to be driven by the large regional changes in insolation driven by orbital changes.

A 2000 - year transient climate simulation with the Community Climate System Model shows the same temperature sensitivity to changes in insolation as does our proxy reconstruction, supporting the inference that this long - term trend was caused by the steady orbitally driven reduction in summer insolation.

Gradual, insolation - driven millennial - scale temperature trends in the study area were punctuated by several abrupt climate changes, including a major transient event recorded in all five lakes between 4.3 and 3.2 ka, which overlaps in timing with abrupt climate changes previously documented around the North Atlantic region and farther afield at w4.2 ka.
