Global warming is happening, and easily measurable and observed with the naked eye. Obviously large forest fires have occurred before humans doubled atmospheric CO2 levels in the last century.

The idea it is either natural or the result of human caused climate change is a false choice. The question is how much climate change is increasing the frequency and severity of them as a contributing factor. They occur naturally and climate change is predicted (and has so far been accurate) to make them more frequent and worse. Like hurricanes and droughts.

Doubled? No. From Wikipedia:

> Global annual mean CO2 concentration has increased by more than 45% since the start of the Industrial Revolution, from 280 ppm during the 10,000 years up to the mid-18th century[2] to 415 ppm as of May 2019.

I know, it's Wikipedia. If you've got a better source, cite it. Until you do, "doubled" is hyperbole.

If you want to persuade people that anthropogenic climate change is real, easily-disproved overexaggeration isn't the way to do it.

Look, you're right. I base off 250 (10k yrs ago) and looking at current 415 and carelessly using an order of magnitude type phrasing. It's not up 100.0%. It's between 50-100% and on the lower end.

Yeah, well, I've never been imprecise here on HN. Never rounded my data to an order of magnitude. Nope. Never. (I, ah, may have rounded toward zero a bit in this paragraph...)

Now I feel like "Captain Nitpick" for my previous comment.

No, I had to acknowledge you are right, and good for you for holding me to the higher standard! Particularly on this topic.

So firestorms aren't natural?

I stated explicitly that they are in my comment.

Obviously large forest fires have occurred

Firestorms are distinct from "large forest fires', but point taken.
