New paper finds global cloudiness decreased over past 39 years
'Published inJournal of Climate finds that from 1971 to 2009, 'Global average trends of cloud cover suggest a small decline in total cloud cover, on the order of 0.4% per decade.' Thus, over this 39 year period, global cloud cover decreased 1.56%. This decrease in cloud cover alone could account for all global warming since the 1970's'
As Dr. Roy Spencer points out in his book, “The most obvious way for warming to be caused naturally is for small, natural fluctuations in the circulation patterns of the atmosphere and ocean to result in a 1% or 2% decrease in global cloud cover. Clouds are the Earth’s sunshade, and if cloud cover changes for any reason, you have global warming — or global cooling.”
