Sentences with phrase «orbital effects»

Also, the onset of glaciation or deglaciation appears to be triggered by orbital effects that have big seasonal / regional impacts but apply almost zero RF in the global mean.

The two principal mechanisms by which the orbital effects on the regional / seasonal distribution of insolation instigate climate change are melting / growth of ice sheets (thus albedo change — > temperature change) and the slow feedback effect of GHGs responding to temperature change, thus increasing the greenhouse effect.

This is an issue because we know there is a substantial long - term natural cooling trend for high - latitude summers because of Earth orbital effects, but the trend is nearly zero in the global annual average.

Due to the earth's spherical shape and orbital effects, annual incoming solar radiation at the poles is so low, polar regions always radiate more heat back to space than is ever absorbed locally.
