Last time Earth hit these CO2 levels there were trees at the South Pole

Considering that in many places the temperature rapidly changes from 20 degrees in the winter to 100 degrees in the summer without catastrophic sequelae I am thinking we are good.

Bizarre. Why would you think that short-term variability would mean we have no problem with long-term changes?

Species, ecosystems, and human societies have ways of dealing with seasonal temperature variations, through short-term coping mechanisms. But that doesn't mean that longer-term changes of that sort can be adapted to the same way.

I don’t care about global warming but that has nothing to do with my desire to see all leftists suffer.

I see it as more of a general misanthropy, rather than specific to that group. If you cared about ANYONE you'd care about global warming.

We've never been through a period of global warming anywhere near this fast. There are two issues the low-IQ set has, which cause them to cite graphs like the one you did:

(1) They can't tell the difference between local warming and global warming, so they'll point to a single site to try to make a point about the globe as a whole.

(2) They have no grasp of timescale, so they'll point to a graph that's so compressed that it's impossible to gauge the speed of warming on a scale relevant to the current period of anthropogenic warming.

As to that latter point, take a look at the graph. In pixel terms, it's about 676 pixels wide, and covers a period of about 425,000 years. So, every single horizontal pixel marks about 629 years. Thus, the entire period of the current instrument record (1880-2019) would take up about 1/5 of one pixel. The industrial era would not even show up on that graph -- disappearing between pixels.

So, take a look at one of those temperature spikes.... say, the most recent one. It runs from abut -8 degrees Celsius to about 2 degrees Celsius over the course of about 13 horizontal pixels. That's about 8,180 years.... a period longer than the whole history of human civilization. So, even in that very rapid period of local warming, we're talking about a warming rate of about 818 years per degree of warming. By comparison, since 1975, warming has been happening at a rate of about 1.5-2 degrees C per century. We're talking about warming currently happening at a pace over a dozen times what you see in the steep parts of your graph.

Of course, that's all obvious at a moment's glance to anyone with a science background, or at least a decent IQ. But it never even occurs to the dummies on the right, who will post graphs like that, imagining foolishly that they support their case. How can one even discuss such matters with people that thick?

1) You think human civilization is less than 10k years old???

2) Did you ignore the data set from NOAA/NASA?

3) Do you comprehend what the little ice age is? You think the Earth is going to naturally warm coming out of the little ice age? You think it coincidence that the AGW fear mongering religious cult start their data projections based on the end of the little ice age?

4) Do you comprehend the correlation between sunspots/solar flares and the Earths temp? Do you realize other planets are also warming? Hmmm...

You mean when MAN and HIS carbon footprint could not have possibly played a part in that natural cyclical event? :thinking:

What part of "Man's carbon footprint" brought about the greatest warming in this epoch...the end of the last Great Ice Age, that created glaciers out of 1,000+ meter ice sheets of ice, as it retreated across the upper third of the Northern Hemisphere, creating the Great Lakes, etc.?

What act of "man" caused that, and where is warming even ROEMOTRLY CLIOSE TO THAT LEVEL, taking place now?

Wow, you didn't understand anything I wrote, did you? Here, let me help. Take the last of those three as an example. What do you think the pace of warming as then, in terms of degrees of warming per century? You don't need to be exact, but be specific. Do you think the pace was around 2 degrees per century? Around one? Around a tenth of a degree per century? And what do you think the pace is now? Again, you don't need to be exact, but be specific.

Since 1880 it has increased by about 1 degree.

^ So when the Climate Deniers are no longer credibly able to argue that there was a vast conspiracy of climate scientists faking the data and perpetrating a hoax, they are left with claiming that they are perfectly fine living with a human-induced climate catastrophe because they can live off the land.

But I actually think you are lying your ass off about being a rugged survivalist fully prepared to survive either climate catastrophe or zombie apocalypse.
When you really think about it, lying is what we have come to expect from the Climate Denier community.

LMAO... truly ironic when someone calls others 'climate deniers' and then talks about 'credibility'

How many more times can this leg humping stalker prove what a cowardly unethical liar he is?

^^ A disingenuous question, which parrots something you read on a rightwing blog, and I am sure you did not come up with this line of reasoning independently yourself.

Actually I did. I co-authored two papers, one in undergrad and one as a resident. With that experience I read these so called climate papers with a little more scrutiny than a politician. Well, a lot more actually. I've not seen one of these papers that could pass the criteria needed to get published in Compendium, e.g.

To even ask this question comes from either abject ignorance, or an overt embrace of dishonesty and deception.

Humans have only been around for about 25,000 years...and the first ~15,000-20,000 of those years wasn't civilization, it was mankind wandering around, looking for a warm place to set up camp near a herd of animals.

Do you comprehend that even a slight 1-3 degree change in the average global temperatures has massive effects to the planet's ecosystem?

If the oceans were just 3 degrees warmer, most of the life in it would die.

Which one? The one that has 'consensus on consensus' in the title ?
My reviewer would have crumbled it up in front of me without reading any further if I presented a paper like that.

LOL!

You know why Venus is warming?

BECAUSE IT HAS A GREENHOUSE EFFECT.

What a fucking idiot. Why do Conservatives continue to posture that they're thinkers and scholars when they're not?
