Global Temperature December 10th 2025 3.52°C 38.3°F.

Incoming solar irradiance 350.96 w-m2 (sun distance 147 million km) minus optical depth 116.75w-m2, of which 19.48 watts is reflected, means (234.2w-m2 + 97.27w-m2) irradiance, total 331.48 thermal heat for the earth. Giving the earth a temperature of 3.52°C.

Global Temperature 3.52°C (38.3°F) December 10th 2025

Total Solar Irradiance for December 10th 2025 is 1403.86 watts per square meter. The optimal thickness at zenith means 1043.86 means the global mean is 104.4 watts absorbed incoming solar irradiance. Also albedo has increased due to snow and ice, which means not all of the 246.58 watts is absorbed at the surface. An extra 19.48 watts is reflected, meaning only 227.09w-m2 is absorbed at the surface. This makes the global mean temperature at 3.52°C.
