Orbital theory climate
WebOrbital 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 2) at latitudes of 60 degrees) [citation needed]. WebThe Milankovitch orbital hypothesis on the climate effects of orbital precession, obliquity, and eccentricity is now generally accepted as a primary pacing mechanism for late …
