Past Global Warming Similar to Today’s


#1

Dec. 15, 2014 – The rate at which carbon emissions warmed Earth’s climate almost 56 million years ago resembles modern, human-caused global warming much more than previously believed, but involved two pulses of carbon to the atmosphere, University of Utah researchers and their colleagues found.

The findings mean the so-called Paleocene-Eocene thermal maximum, or PETM, can provide clues to the future of modern climate change. The good news: Earth and most species survived. The bad news: It took millennia to recover from the episode, when temperatures rose by 5 to 8 degrees Celsius (9 to 15 degrees Fahrenheit).

“There is a positive note in that the world persisted, it did not go down in flames, it has a way of self-correcting and righting itself,” says University of Utah geochemist Gabe Bowen, lead author of the study published today in the journal Nature Geoscience. “However, in this event it took almost 200,000 years before things got back to normal.”

Yes, it’s not the end of the world as we know it, and man’s contribution is negligible at best.

Global warming as a policy driver has actually hurt the environment. :yup:

But WE ARE ALL GONNA DIE!

Unpleasant but true, with or without AGW.

Not similar is the cause.

Now, its just a hypothesis of mine, but I attribute global warming to all the hot air expelled our of the yaps by those who have made it a the “hottest” (excuse the pun) political issue of our day, both on the right and on the left
:eek:
