I can't back it up because it was a televised congressional committee hearing and I don't remember the name of the scientist but he said that his data he had been studying and working with that was published in the 1940's was different from the data that is now published for that same time period. He made no accusations he just said his data showed no signs of global warming. So, I guess as a skeptic, yes this does m…

You don't think techniques have improved since the 1940s?

Of course the data would be different with 60-70 years of improved collection techniques, analysis tools, and theoretical knowledge about the climate.

We're technically still in an ice age [1]. How far does this need to go to reach the end of that ice age [2]? The Cretaceous period was over ten degrees warmer than our current period [3,4,5]. It supported a lot (though much different) biodiversity. How long would it take us to push into these temperature ranges? And how long to exceed them? How much species diversity will we lose at each half degree increment from t…

Climate change deniers tell each other we are coming out of The Little Ice Age that started in 1200AD. Which is technically correct. What they don’t tell each other is that “Little” is an understatement and we shot way past the prior “Medieval Warm Period” long ago and are only accelerating. https://en.m.wikipedia.org/wiki/Little_Ice_Age#/media/File%3...

I read what you wrote several times and I still don't understand what your point is.

Can you please elaborate?

Not my claim. We also have plenty of fossil fuels to put into the Haber process until we transition into fusion, even if that's in the distant future.

Sure, humans do that until they industrialize, then they slow down.

I think it’s an ice age while any point on earth (not counting mountains etc.) has year-round ice. We’ll be in serious trouble long before that changes.

As I understand it, there was no glacial ice on earth during the Cretaceous. Water covered much more of the earth's surface. There were lots of dinosaurs, insects, and other biodiversity that thrived during this time. Our current biodiversity evolved to fit cooler temperatures, obviously, so the quick change is a huge fitness gradient challenge that many species will not overcome. And in certain food webs, it may res…

I think humans are one of those species, as they cannot survive wet bulb over 95f nor can current populations survive across the collapse of agriculture, hence the problem

The conspiracy-minded part of me really wants to link this year to the sulfur reductions in ship emissions kicking in this year. The fact that there's basically only one person really trumpeting this in a way kind of indistinguishable from things I know are false is hard though. Hank Green pointing out that we could just spray water into the air to get the same effect (and avoid the whole "sulfur" thing in general) g…

Not sure what the "conspiracy" would be, but yeah, the sulfur reductions in ship emissions is definitely a factor. Someone needs to figure out large scale injection of SO2 to the stratosphere. Don't wait for permission, just do it!

> Someone needs to figure out large scale injection of SO2 to the stratosphere. Don't wait for permission, just do it!

I wonder if a hundred years ago someone said "Someone needs to introduce the cane toad to Australia to reduce the beetle population! Don't wait for permission, just do it!".

Not the exact same thing, sure, but we are terrible at predicting side effects.

What are you skeptic of? There is so much misleading denialism of what is now ao blindingly obvious to any casual reasonable observer, that I propose you apply you skepticism with a bit a cui bono.
