Sentences with phrase «what orbital changes»

We know how the planets behave in relation to the sun and to each other today, but venturing millions or billions of years into the past, it can be tricky to figure out what orbital changes may have impacted the Earth's climate.

Not exact matches

He then uses what information is available to quantify (in Watts per square meter) what radiative terms drive that temperature change (for the LGM this is primarily increased surface albedo from more ice / snow cover, and also changes in greenhouse gases... the former is treated as a forcing, not a feedback; also, the orbital variations which technically drive the process are rather small in the global mean).

So albedo change (owing to changes in orbital forcing, which is what melts the ice sheets) was comparable to, and probably larger than, the CO2 change.

Christy et al provide descriptions of what they changed due to orbital adjustments or overlaps as opposed to tracking surface temps and krigging between thousand mile apart un measured projected temps.
