What do you mean exactly?

https://climate.nasa.gov/explore/ask-nasa-climate/3071/the-r... > Scientists have been building estimates of Earth’s average global temperature for more than a century, using temperature records from weather stations. But before 1880, there just wasn’t enough data They always says "on record" or "ever measured" in these headlines. Which means it's since ~140 years, and we know that is very very likely that past tempe…

Does it even matter if it was warmer in the past? Right here, right now, we can prove that human efforts have changed the temperature of the planet. Right here, right now, we can see the effects of that change. Increased frequency of storms, increased intensity of storms, shifting of seasons, decline in animal populations, etc. Being a "skeptic" just because you can't prove that it's currently warmer than it was 200 years ago is pointless

About 0%. Looking at historical timelines, the rapid change we are seeing now is unprecedented. The forced heating lines up exactly with the additional C02 and methane we have pumped into the atmosphere. We are causing this, full stop.

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

Yeah, it is a mistake to worry about the earth in regards to climate change. It will be fine. Biodiversity may in fact increase after the bottleneck. Humans though, or at least human civilization...

> (you) The earth is getting greener, rapidly. The maximum human carrying capacity is probably higher

The actual myth (read beyond the title):

"CO2 is actually the "food" that sustains essentially all plants on the face of the earth, as well as those in the sea. And the more CO2 they "eat" (absorb from the air or water), the bigger and better they grow"

As I understand this exchange, you've challenged the claim that climate change will negatively impact agriculture by pointing out that Earth is getting greener, supported by yours

> Hint: The green stuff is food, for either humans or animals humans can eat.

The page I've linked debunks exactly this.

> A specific plant’s response to excess CO2 is sensitive to a variety of factors, including but not limited to: age, genetic variations, functional types, time of year, atmospheric composition, competing plants, disease and pest opportunities, moisture content, nutrient availability, temperature, and sunlight availability. The continued increase of CO2 will represent a powerful forcing agent for a wide variety of changes critical to the success of many plants, affecting natural ecosystems and with large implications for global food production. The global increase of CO2 is thus a grand biological experiment, with countless complications that make the net effect of this increase very difficult to predict with any appreciable level of detail.

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

Overshoot is not only about population, but also about consumption and pollution.

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...

That chart covers a very short duration. Here's a more complete chart of Earth's temperature: https://en.wikipedia.org/wiki/Geologic_temperature_record#/m... As you can see, we are indeed coming out of one of the coldest periods ever in Earth's history.

... and based on that chart are now hotter than any time in the last 100k years, heading into the last few million. A few 10s (of million) years at +25c are going to be the "new normal"? I'm trying to understand the point. The rate of change is quite dramatic, and the last time (Eemian) there was anything like this there were "rapid" 12c oscillations.

Humans didn't exist. I suspect most current plant/animal species are "devolved" by such swings.

Dont let global warming get you down, civilizations die all the time, just like that, why ours could wake up dead tomorrow.

Part of me feels sad, part of me feels dread, and part of me says, "well, we're just reaping what we have been (and still are) sowing, and we collectively deserve all that is coming." All the suffering sucks though.

Only some are more culpable than others. The climate crisis represents the single biggest failure of humanity. How stupid do our leaders need to be to know about an extinction level event (or at least one that threatens the breakdown of civilisation) with > 50 years notice and take no substantive action? They should be charged for crimes against humanity.
