Did you know the physics of the greenhouse effect was worked out closer to the invention of the steam engine than today?

Back in the 19th century (deniers: we're currently nearly a quarter way through the 21st century). I'm goaded, but I want an audience that includes the multitude that have blocked me, especially the global warming deniers.

Unless it has changed since I started typing this, Florida is NOT under ten feet of water; despite it being well after 2001. Maybe if you used models from AFTER the invention of the stop sign, you could take actual data into account, and be taken seriously- though that WOULD require acknowledging far more dangerous greenhouse gases, rather than harping on endlessly about CO2, as well as not placing all the blame on the country responsible for less than ten percent of emissions.

I guess unwarranted oikphobia is more important than saving the planet.

You mean a worst-case scenario didn't happen, so once in a decade storms every few months isn't anything to do with global warming?

Yes, carbon dioxide is not the only greenhouse gas, methane, for example, is far worse. The scientists at the time calculated the effects of doubling carbon dioxide. We're not there yet.

"The current global average concentration of carbon dioxide (CO2) in the atmosphere is 421 ppm as of May 2022 (0.04%). This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century."

I have heard that. And there was more respect for science and research back then. Arnold Schwarzenegger made a good point in an interview: He completely leaves out terms like climate change, greenhouse effect, global warming… and only talks about protecting the environment. Even the most dense of GOP rubes can get behind protecting the environment. 👍

[Asker]

No, they can't. They can't even get behind protecting their neighbours by distancing or wearing masks.

Republicans turned against science about the time Gingrich recorded an advert about global warming with Pelosi.

This is good but I would caution that the term "greenhouse gas" is effectively shorthand for what's going on. Yes, it traps heat, but there is a balancing effect to that which then just expands the atmosphere - something not possible in an actual greenhouse.

However, the ability to exchange heat is also inhibted so the void of space doesn't wick away the heat as efficiently. That's the mechanism that will kill us.

[Asker]

I'm pretty sure greenhouses expand in the heat, too. Venus is the ultimate greenhouse gas planet.

Greenhouses were built in 30 AD. But greenhouses and greenhouse effects are different.

I was aware that the effect was noted early. You could date back to 1856 when absorption of gasses was first investigated.

Yes i did and global warming deniers are either ignorant or too scared to accept the truth.
