Another Assumption underpinning AGW falls

Warmists hardest hit

The latest entrant to the AGW skeptics is NASA.

Goddard Space Flight Center has been studying actual observed values of Solar Radiance (assumed to be a constant by warmists), and now have data on two successive solar cycles.  As constants go, it has significant variability.

 

NASA admits all previous warming trends caused by sun

Now, however, new study released from NASA’s Goddard Space Flight Center in Greenbelt, Maryland measuring the global temperature variance during the past 100 years has found the sun’s heat and variable cycles have indeed made a significant, measurable impact and greatly influenced Earth’s climate.

In fact, the influence extends as far back as the Industrial Revolution.

Goddard’s research shows that the solar cycle’s ups and downs directly affect the temperatures and long term climate. During solar minimum they discovered about 1.36 watts per square meter of solar energy hits Earth’s mesosphere; solar maximum escalates to 1.40 watts per square meter.

It’s well-known that the sun passes through cycles of 11-year and 22-year intensities. Currently, the sun is on the upswing towards solar maximum when sunspot activity and solar flares will peak. The height of the maximum is expected during 2012-2013. Earth now cooling

After the current peak, NASA and other space agencies believe the sun will go unusually quiet for the next 30 years or more.

 

The correlation between documented warm periods, documented cold periods, and solar cycles has been well documented for years. Now we have the data proving that the solar radiation constant isn’t.

The narrative seems to be having issues with reality.
