Atmospheric General Circulation Changes Due To Increased Greenhouse Gases

The animation shows how the atmosphere’s general circulation is expected to change in 50 or 60 years as a result of increasing greenhouse gases. Air currents rise on both sides of the equator, flow toward both poles and sink, then return to the equator at lower altitudes. In the future, the currents near the equator will strengthen and loft clouds higher into the atmosphere. In the mid-latitudes, clouds will be more sparse, making the air drier and hotter. The sinking air flow will shift farther toward the poles, with more clouds building up closer to the polar regions.
