Changing sun, changing climate

Quote:

Incidentally, but importantly, BEST's own data also clearly invalidate the alternative hypothesis that CO2 is the most important cause of observed temperature changes across the USA.

In a nutshell, climate is always changing and it is the sun wot does it.

Comment:

If CO²  doesn't do it, but the sun does do it, then we ought to tax the sun instead of CO² .
