  Solar Activity

'
So the very source of our heat, a star who's output is wildly variable, isn't necessarily responsible for global temperature?

no known physical mechanism has yet been found explaining how solar activuty affects Earth climate...

my comment:


I wonder if these 'scientists' included climate scientists.

Sunspots cover very little of the Sun's surface.
Our weather and climate have time lags due to convection heat transfers.
The major factor for the world's weather is the oceans. Our water planet has much more water surface than land. Water dissipates heat slower than air.
The sun's slightly varying output is primarily warming the oceans with less warming the land which warms the air by convection.
The ENSO cycle in the Pacific warms the air with the periodic transfers of heat from the warm pool which alternates sides of the large ocean. The Pacific Ocean cycles have more impact than the minor solar variations. The other, smaller oceans have less impact. The less dense atmosphere has a daily impact but less prolonged impact other than clouds reflect more light. Cosmic rays are proposed to affect cloud formation so Earth's magnetic field, affected by the Sun, has an affect on Earth's weather via clouds. The sunspot cycle affects the Earth only if the Sun's radiation is dipping significantly, as it apparently did in the Maunder Minimum. air with the periodic transfers heat from the warm pool which alternates sides of the large ocean.
