Second, with less cloud cover, more infrared radiation can escape to space, thereby creating a strong climate - stabilizing negative cloud feedback that prevents significant warming from increasing greenhouse gases. (realclimate.org)
Similarly, during periods of high solar activity, less clouds form, leading to global warming. (globalwarmingsolved.com)
According to the hypothesis, then, less cosmic radiation would mean less cloud formation and, ultimately, warmer temperatures — precisely what was observed during the 20th century. (foxnews.com)
