I was rereading my Milestones post below and was struck by an idea. Think of the difference between winter and summer, that is the impact the sun, our star, has on life on Earth, our planet.

Nothing we humans do has anything like that impact, not even close. I don’t find it hard to imagine that the absence of sunspots has a large influence on climate. I do find it hard to imagine that the creators of climate models have correctly gauged the impact of increased levels of CO2.

Climate does change, it has done so forever. There were once lakes and trees where the Sahara now spreads. Whatever is changing climate is preexisting and not under our control. At best, we can utilize technology to cope with the climatic “hand” we’re dealt.
