Scientists Determine CO2 Levels Must TRIPLE To Yield A Tiny 0.5 W/m² Forcing At The Ocean Surface
By Kenneth Richard on 25. January 2021
Oceans cover 71% of the Earth’s surface. An analysis of CO2’s radiative effect on ocean temperatures finds CO2 forcing is negligible even after reaching a concentration of 1,071 ppm.
In the tropical oceans, 500 to 1,000 W/m² of solar radiation uniformly heats the first 2 meters of the ocean surface by 2 Kelvin in a span of just 12 hours.

The solar radiation reaching the Earth’s surface has increased by about 3 W/m² since 1980 (Delgado-Bonal et al, 2020) due to the cloud cover variations that are of “the utmost importance for current climate change†because they “ultimately determine the SW [shortwave] radiation.†This solar radiation increase can explain the recent warming trend.
