CO₂ puts heavier stamp on temperature than previously thought, analysis suggests

A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on Earth from 7 to a maximum of 14 degrees. This is shown in the analysis of sediments from the Pacific Ocean off the coast of California, by researchers at NIOZ and the Universities of Utrecht and Bristol. Their results were published in Nature Communications

"The temperature rise we found is much larger than the 2.3 to 4.5 degrees that the UN climate panel, IPCC, has been estimating so far," said the first author, Caitlyn Witkowski.

The researchers used a 45-year-old drill core extracted from the bottom of the Pacific Ocean. "I realized that this core is very attractive for researchers, because the ocean floor at that spot has had oxygen-free conditions for many millions of years," said Professor Jaap Sinninghe Damsté, senior scientist at NIOZ and professor of organic geochemistry at Utrecht University.

7-14C is absolutely gobsmackingly insane compared to the previous estimate of 3-4C. And we'll hit the doubling point around 2060 at currently rates of carbon emissions (3-4ppm/year now)

Either there's a serious error with their methodology, or we're fucked with a capital F

1. Yep...

"7-14C is absolutely gobsmackingly insane compared to the previous estimate of 3-4C. And we'll hit the doubling point around 2060 at currently rates of carbon emissions (3-4ppm/year now)"

And that only takes into account WHERE our current emissions stand now, but doesn't include the fact that those emissions are not a static number and are constantly INCREASING year after year.

As with practically every forecast or prediction concerning climate change and the devastating effects we will be suffering from it, this forecast will also happen much sooner, and much more intensely than we are expecting.
