Yes, cosmic rays and solar activity DO impact the planet's climate.

This paper is from 2024, not from 1999.

It's interesting because I was arguing with a guy who claimed to be an astrophysicist on Facebook (I know, right; why would an Astrophysicist waste time arguing with the mob on a Facebook page?) who was mocking Sally Baliunas and the cosmic ray theory. I found this to rebut at least one of his points (I was at a disadvantage because he had a suspicious amount of data, most especially papers, at his disposal while I had to look a lot of this stuff up to rebut him, and that is hard given the way search engines hide such papers that disagree with the alarmist view.) He claimed to know Baliunas personally, yet spoke quite ill of her, so it's obvious he was either lying or had a grudge. At any rate I pointed out that yes, science is admitting cosmic rays influence the climate and I further argued that many of the criticisms he made of her were immaterial. He hasn't responded since yesterday, even though he was quick to reply back then (too quick, given he kept bringing up papers I couldn't get into to read; methinks he had a "how to talk to a skeptic" website and now has given up to blather on elsewhere. In short I think he's a paid troll, and I told him as much. Oh, one thing, he used "type II and TypeIV when referencing stars, a designation I had never heard before, back when I studied astronomy in college and I asked him about it; why not use G2 or K8 or one of the spectral designations and he did not reply, leading me to question his knowledge of the subject. I tried looking up those designations and got Pokemon pages but nothing about astronomy.

At any rate this shows that cosmic rays are an impact on climate, one not in the models. And there were other papers I found while looking.

Now, there are two kinds of cosmic rays - Galactic and Solar. The galactic appear to be as the solar wind output has declined,  

In our current case cosmic rays are probably not creating clouds as it is more active than any time in the last eight thousand years, according to NASA. More solar wind means fewer cosmic rays, which means less cloud cover. We KNOW cloud cover has been in a serious decline, especially since 2000. While we can debate the meaning of all of this, and the cause, we cannot dispute that last fact; there are fewer clouds and thus more solar radiation reaching the Earth's surface. More sun means more warmth.

I pointed this out to the guy and he simply dismissed it without addressing it. An astrophysicist should have been all over that.

At any rate the chilling stars appear to be less chilling these days, and it's not the fault of plant air.
