Catastrophic, Anthropomorphic, Global Climate Change

First, the closest star is a main sequence variable; its output will vary.  Literally by definition.

Second, because of our proximity to this star, the climate will ever be in flux.

Third, that means that while the changes may, indeed, be catastrophic, they are very unlikely to be anthropomorphic.

I've said it for years.

I note that the coldest winter I can recall since I moved to the Gunshine State is occurring right after the sun made almost no sunspots for better than a year.

Either that or what recycling and carbon crediting we did worked beyond our wildest imaginations.

I'm still betting on the sun.
