The warming trend is unlikely due to changes in the sun’s output, which has not varied substantially as temperatures have risen.


We’ve been reading the US National Climate Assessment and found it quite impressive!

We thought we’d share a series of images we think tell the story of what’s going on.

This is the 7th of 9 in the series.



Via the report: “The full record of satellite measurements of the sun’s energy received at the top of the Earth’s atmosphere is shown in red, following its natural 11-year cycle of small ups and downs, without any net increase. Over the same period, global temperature relative to 1961-1990 average (shown in blue) has risen markedly. This is a clear indication that changes in the sun are not responsible for the observed warming over recent decades.” (U.S. Global Change Research Program)
