In A Few Days Clouds Affect Earth’s Radiation Budget By More Than CO2 Does In 270 Years

Scientists continue to affirm the critical role of clouds in modulating the Earth’s energy budget, and, hence, the climate.
The total net forcing of the entirety of the CO2 influence on climate has been less than 2 W/m² since 1750 (Feldman et al., 2015).

On a per-decade basis, a 22 ppm rise in CO2 – realized about every 10 years in recent decades – is associated with a forcing of just 0.2 W/m² (Feldman et al., 2015), but only when the sky is clear of clouds. And cloud-free skies are rarely ever observed in the real world atmosphere, as “less than 10 percent of the sky is completely clear of clouds at any one time” (NASA, 2015).
The Cosmic Ray-Cloud-Radiation Budget Link Affirmed
In a new study published in a Nature journal climate scientists Dr. Svensmark and colleagues have determined that cosmic rays, or variations in ionization, are strongly linked to the formation of aerosols and clouds, and that “low liquid clouds are mainly responsible for the change in net radiative forcing.”
The decreases in ionization during cosmic ray minima have been observed to occur over 80% of the globe in a matter of days, with the primary responses over the Earth’s oceans. Thus, the response is global in scope.
