Global Brightening

A new study published in the Journal of Geophysical Research - Atmospheres finds decreased cloud cover has resulted in a significant increase in solar radiation over the US from 1996 to 2011. Increases in infrared surface radiation dwarfs the alleged warming contribution attributed by Warmists to rising CO2 levels during the same time period.  To simplify,  sunshine has had 4.4 times greater effect on surface temperatures than increased greenhouse gases.

These findings add to many other peer reviewed papers documenting a global decrease in cloud cover or ‘global brightening’ over various periods and locations beginning the the 1980’s. This decrease in cloud cover alone could account for all global warming observed since the ice age scare of 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.
In all fairness, this basic concept has been known for some time, but those scientists whose greenhouse gases theory is threatened, have pointed out that in the past century, there have been periods of "global dimming" as well.  They would have us believe that man's air pollution and aerosol gases are responsible for the dimming. But man has not caused the trend of warming that has prevailed since the last Ice Age, many thousands of years ago.

    Now if THAT isn't a reason to start singing "Wait 'til the sun shines, Nelly"...I don't know WHAT

    So what these guys are saying is that the EARTH is responsible for all this stuff...

    Lemme see if get the gist of this...more clouds = less sunlight = global COOLING.
    Less clouds = more solar radiance = global WARMING??
    Got it!

    Excellent post.

    Stay safe out there.
