i have not seen any compeling arguments climate change is man caused.
and guess what?
It was WAY WAY WAY hoter 4000 years ago, and humanity didn't die out
the biodiversity did just fine, the balance of predator and prey survived
so what damages are you talking about excactly?

>>14579022
Just post ONE study with a clear methodology that proves global warming is man made

then show me those
I can only find newer articles(after 2007)
Saying its proven wrong
https://www.newscientist.com/article/dn11646-climate-myths-the-hockey-stick-graph-has-been-proven-wrong/
Or michael mann himself writing puff pieces about himself
https://blogs.scientificamerican.com/observations/earth-day-and-the-hockey-stick-a-singular-message/
and no, it being the hottest its ever been in 1400 years means nothing

>that graph shows a break in a 800,000 year correlation
You are confusing missing data for a break. The ice core data ends in 1855.

That longer timescale graph is indeed deceptive.

GISP is not the same as GISP2 and ice cores aren't global, but nice try.

Quote from the author of the study, Richard Alley

>"Whether temperatures have been warmer or colder in the past is largely irrelevant to the impacts of the ongoing warming. If you don’t care about humans and the other species here, global warming may not be all that important; nature has caused warmer and colder times in the past, and life survived. But, those warmer and colder times did not come when there were almost seven billion people living as we do. The best science says that if our warming becomes large, its influences on us will be primarily negative, and the temperature of the Holocene or the Cretaceous has no bearing on that. Furthermore, the existence of warmer and colder times in the past does not remove our fingerprints from the current warming, any more than the existence of natural fires would remove an arsonist’s fingerprints from a can of flammable liquid. If anything, nature has been pushing to cool the climate over the last few decades, but warming has occurred.

Also that dataset ends in 1850 and from one regional site in greenland. This is what it looks like if modern data were plotted on top

>he thinks that the greenland summit ice cores go past 1855
>he doesn't realise that easterbrook is a hack
>he hasn't even questioned the validity of his source

pic related, your ice core rebuttal with data points added for 1855 and 2009, now tell me if that's not unprecedented warming
