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

7/9 

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)
