A rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged the warming for many thousands of years, according to scientists.
Their study, published online in Nature Geoscience, provides new evidence of a climate feedback that could explain the long duration of the Paleocene-Eocene Thermal Maximum (PETM), which is considered the best analogue for modern climate change.
The findings also suggest that climate change today could have long-lasting impacts on global temperature even if humans are able to curb greenhouse gas emissions.
"We found evidence for a feedback that occurs with rapid warming that can release even more carbon dioxide into the atmosphere," said Shelby Lyons, a doctoral student in geosciences at Penn State. "This feedback may have extended the PETM climate event for tens or hundreds of thousands of years. We hypothesize this is also something that could occur in the future."

So in January, 2119 Fairbanks will be -49 instead of -50?

Flamingtext.com is great, SunkenCiv. You get lots of choices in the way to display the GIF (font, transparency, color of text, border of text.
NICE. Thanks.
I for one, am abundantly terrified.
Lol
“It can start warming up any day now...”
Not to worry, I have it on Good Authority that by July things will have warmed up nicely in your neighborhood.
I think there are various downloadable programs that will do this kind of thing, as well. :^)
The buzzards have gone North
The Robins are here
Winter is over
LOTS of fonts, if memory serves, plus the canned presets are generally pretty nice combos. The other one is cooltext.com.
I think Frontpage is the one you used to generate that interesting tag (which is now supported on most browsers) that freezes the background image on web pages, so scrolling doesn't have an impact on the background. Handy.
That’s right. I think it is called a frozen background.
If it weren’t for climate change we’d still be living in caves, if we were still living at all.
In other words, they found nothing.
"Evidence" of "feedback" is an "if then if" supposition. "Feedback" would be some correlating event that parallels warming. "Evidence of feedback" would be something that might point to the existence of something else that is feedback of something that causes warming.
All of this happened in "ancient" times, and yet they went straight to making assumptions about today.
Emanations from penumbras in the Constitution have a more solid foundation than this "evidence of feedback" of causes of global warming.

A much closer problem is the certainty of another ice age in the Earth's near future. It is problematic that our present civilization could survive glaciers over New England, Manhattan, the Upper Midwest and Northern Europe. Evidence suggests there have been seven attempts for humans or ancestors to colonize Great Britain. We are on the seventh and all the previous attempts failed, succumbing to the ice and cold. The only habitable parts of Europe in the last ice age were refuges in Southern Spain, Southern Italy and Southern Greece.
So, if the present levels of CO2 continue to increase and somehow stop the present long term climate cycle so that Earth does not plunge into another ice age, that would be a very good thing indeed for human civilization and the Earth. Unfortunately, it's all based on politicized junk science.
Great Britain was settled each time, and occupied for thousands of years, but the occupation may have ended with the next glaciation. Trouble with really thick glacier cover that goes on for hundreds of miles is, nothing much to eat, and no fuel for fires. Even the sudden formation of the English Channel didn't slow down prehistoric humans.
Also, I'm not on board any gradualist onset models.
It's interesting that "fossil" CO2 levels found in deep ice cores show that the CO2 levels rose 100s or 1000s of years *after* the world warmed back up.
The ice core data also support that the onset of an ice age is rapid. I'm glad I won't live to have to cope with it.
Food production will rapidly decline. Glaciers don't come as far south as Colorado (mountain glaciers excepted) but this land will be useless. Weld County, Colorado, is one of the most productive agricultural counties in America. Next ice age, it will be tundra. Great Plains agriculture will be lost. Populations will flee south and there will be great wars over the reduced livable land.
If only the warmist fantasy was true.
