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?

eschelon said that we are in an ice age and multiple people asked “how can you call this an ice age?” I either didn’t see the linked reference or it wasn’t there when I read eschelon’s comment.

Either way, I’ve seen the Little Ice Age come up enough lately to be extremely irritating. So, I knee-jerked the rebuttal.

Now I think eschelon was actually asking if we are overriding the https://en.m.wikipedia.org/wiki/Quaternary_glaciation which would normally take millions of years to happen.

What do you mean exactly?

Let's not beat around the bush. This is standard climate change denialism. It's the trope that there is nothing here to worry about because, who knows, the earth COULD have been warmer in the past and it still exists now. It's the same logic that would say that you've decelerated from 60 mph to 0 before without an issue, so you should be just fine after slamming your car into a brick wall.

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…

Commenters seem to be taking these questions as rhetorical (which they may well be, I can’t really tell), but I’d actually be intellectually interested in genuine answers to them.

> It was the hottest August on record – by a large margin – and the second hottest ever month after July 2023, according to the Copernicus Climate Change Service ERA 5 dataset. August as a whole is estimated to have been around 1.5°C warmer than the preindustrial average for 1850-1900, according to the C3S monthly climate bulletin. Thinking about getting to 1.5 C averaged over the planet is surreal and we are still 3…

Yes, and there’s a lag effect so the temperature will still increase for years after that.

However, to be clear, it’s unlikely we get to net zero in 27 years. We haven’t reached any of our goals so far and the goals only get more difficult

> 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 temperature have been higher not long ago...

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…

> no glacial ice on earth during the Cretaceous

That’s not quite what the evidence shows. The Cretaceous shows evidence for forest near the poles and it’s missing evidence for multiple mile thick ice sheets such as those that recently covered Manhattan Island etc. However currently there’s a glacier 170 km from the equator as altitude drops the temperature, such glaciers likely existed in the Cretaceous.

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.

This is natural progression. The apex predator takes over and over-grazes the land, so to speak, to the point where it no longer supports the apex, so eventually the apex predator dies off, and the other species that are left can flourish.
