Time is running out on the Climate Clock

Another problem is the sun is significantly brighter now than it was during the Paleozoic era.

If this isn't straight BS (I don't know if it is because I don't see a source for it). It's dangerous "what-about-ism" Where it looks like you're trying to say that the problem isn't climate change, but that our sun has changed. As if we didn't live for thousands of years with the current sun setup.

(I feel confident in saying that nothing major has changed about the sun in the last 2000 years because that's not the time scale these things happen on).

I was referring to multi million years so comparisons to the last times we were above 420 PPM the sun wasn't as hot. I'm saying the two are combining is a truly horrifying way. The sun gets about 10% brighter and hotter every billion years, so slight but relentless. https://theconversation.com/the-sun-wont-die-for-5-billion-y...

Yeah, I stand by my original statement. This was not a meaningful 'add' to the conversation.

The sun has been the same brightness for human history. It doesn't make it more difficult than the problem we had 50 years ago.
