Orbital forcing wiki
The Earth's rotation around its axis, and revolution around the Sun, evolve over time due to gravitational interactions with other bodies in the Solar System. The variations are complex, but a few cycles are dominant. The Earth's orbit varies between nearly circular and mildly elliptical (its eccentricity varies). When the orbit is more elongated, there is more variation in the distanc… WebSubsequently, the South Asian monsoon intensified at ~25.8 Ma due to the uplift of the Tibetan Plateau. On the orbital timescale, monsoon precipitation is strongest when eccentricity is maximum. 100-kyr cycles of precipitation were forced by Northern hemisphere solar radiation, rather than the Antarctic ice sheet.

Orbital forcing is the effect on climate of slow changes in the tilt of the Earth's axis and shape of the Earth's orbit around the sun (see Milankovitch cycles). These orbital changes modify the total amount of sunlight reaching the Earth by up to 25% at mid-latitudes (from 400 to 500 W/(m ) at latitudes of 60 degrees) . In … See more It is sometimes asserted that the length of the current interglacial temperature peak will be similar to the length of the preceding interglacial peak (Sangamonian/Eem Stage). Therefore, we might be nearing the … See more • The NOAA page on Climate Forcing Data includes (calculated) data on orbital variations over the last 50 million years and for the coming … See more • Hays, J.
