Show me the math on that.

It's not rocket science mate. I've melts more when it's hotter.

Real science says that man made co2 is a tiny fraction of all co2 in the atmosphere.

Human activity has increased atmospheric CO2 from the pre-industrial 280 or 290 ppm to today's 415 ppm.

In round numbers 30% anthropogenic.

Is that what you're calling a tiny fraction?

Greenhouse gases in the atmosphere (such as water vapor and carbon dioxide) absorb most of the Earth's emitted longwave infrared radiation, which heats the lower atmosphere.

Yes the impact of greenhouse gases is stated per doubling of concentration. The effect decreases with increasing concentration.

I'm not that interested in flat earthers

That's not at issue at all and bas nothing to do with the math. How many BTUs are being retained by man made CO2? Where is the math on that? How many BTUs are retained by other factors? Where is the math on that?

There's lots of papers that decompose the warning into natural and anthropogenic warming.

I'm bored of arguing with flat earthers, but look up Stott et al (2000) , titled something like "control of 20th century warming by natural and anthropogenic forcing" for the first one, and papers over the past 22 years that cite that one. Meehl et al. either 2004 or 2005 has an interesting piece of mathematics showing approximate linearity of the warning to forcing. As in the temperature response to forcing is approximately additive.

But there's a lot of literature for you to read there. Bottom line, natural forcing contributed to dinner of the warning prior to about 1950, but the world would have cooled again since then. Nearly 100% of the warning since 1900 is anthropogenic, and more than 100% of the warning since 1950 is anthropogenic.

I don't have the time or inclination to go through the math in detail with a flat earther, but if you have the inclination to go through it yourself, that should get you started.

That is not a scientific claim at all. Your claim is attributing all co2 to human activity. That is provably wrong.

[–]ActuallyNot 2 insightful - 1 fun2 insightful - 0 fun3 insightful - 1 fun -  (2 children)

The CO2 emitted by human activity is twice that. Some of it had been sequestered, mostly by the ocean.

But if you can prove that wrong, go ahead.

We both know you can't, don't we.

I can disprove your claim just as easily as you can prove it.

[–]ActuallyNot 2 insightful - 1 fun2 insightful - 0 fun3 insightful - 1 fun -  (0 children)

Go ahead then.

Yes the impact of greenhouse gases is stated per doubling of concentration. The effect decreases with increasing concentration.

Do you understand that diminishing effect literally disproves the run away greenhouse effect that your religion espouses?

[–]ActuallyNot 2 insightful - 1 fun2 insightful - 0 fun3 insightful - 1 fun -  (0 children)

I'm not religious.

What do you mean by runaway warming?

This is climate change. The drop in global food production, this year hitting europe, previous years hitting Africa and asia. Coal reef bleaching. Wildfires. Heatwaves. Drought. Flooding. Ice sheet mass loss. That's from there 1.5 degrees we've seen.

If we stop emitting tonight there's 20 years warning in the post. Maybe 1 or 2 more degrees.

Bottom line is you're arguing a straw man, and it's boring.
