Carbon releasing to atmosphere ten times faster than in the PETM

Oh, shit....

"The rate of release of carbon into the atmosphere today is nearly 10 times as fast as during the Paleocene-Eocene Thermal Maximum (PETM), 55.9 million years ago, the best analog we have for current global warming..."

Do you intentionally go out of your way in your free time to frighten yourself, Norfie?
Take solace in this:
"However, the researchers note in the current issue of Nature Geoscience, that the source of the carbon, the rate of emission and the total amount of carbon involved in this event during the PETM are poorly characterized."
In other words, they're guessing.

Read the comments on that page and cheer up, you have a few years of life left, enjoy it and stop being a party pooper.

Which is what inspired the authors to look for better data:
Kump and his colleagues decided to look at information coming from areas that were shallow arctic ocean bottom during the PETM. During a Worldwide Universities Network expedition to train graduate students from Penn State, the University of Southampton, University of Leeds, University of Utrecht and University of Oslo in how projects develop, the researchers visited Spitsbergen, Norway. They uncovered a supply of rock cores curated by a forward-thinking young coal-mining company geologist, Malte Jochmann.

"Deep-sea cores usually have from 10 cm to a meter (about 4 inches to 3 feet) of core corresponding to the PETM," said Kump. "The Spitsbergen cores have 150 meters (492 feet) of sediment for the PETM."

The larger sediment section, made up of mud that came into the shallow ocean contains organic matter that can also supply the carbon isotope signature and provide the greenhouse gas profile of the atmosphere. With the larger core segment, it is easier to look at what happened through time and ocean acidification would not degrade the contents.

"We think the Spitsbergen core is relatively complete and shows an interval of about 20,000 years for the injection of carbon dioxide during the PETM," said Kump.
What they found didn't inspire them to dismiss the risks:
"Rather than the 20,000 years of the PETM which is long enough for ecological systems to adapt, carbon is now being released into the atmosphere at a rate 10 times faster," said Kump. "It is possible that this is faster than ecosystems can adapt."
So a few morons like you in the comment section who couldn't care less about something that won't affect them are dismissive?

If you care about your grandchildren's future, worry about what the experts think, not the idiots.

What does 'worrying' about anything achieve?
Not a lot, you can take my word for that.
My grandchildren will not live to see the next century, unless they live to be 100 plus, by which time, they won't be too bothered about anything much.

I suppose you'll now ask me to care about my great grandchildren's future, even though they may or may not be born?
I'll leave caring about the as yet unborn to you, you're doing a pathetically good enough job for both of us.

Individually, not much. Collectively, everything.

You really are crazy.
Why didn't collective worrying help the many lost civilisations of the past, because I'm sure they all worried a lot before they went under?
-
I'll give you one thing, if you think that collective worrying can cure anything, there's no need for action to stop any global catastrophe or even cancer.
I really am about to ROTFLMAO at your way of thinking.

Wriggle and squirm as much as you like, just admit your 'worry' comment was outrageously funny and have done with it?
-
Stop digging that hole any deeper, just tell me, how, exactly, you've concluded that my, "leanings" are toward fascism?

I could easily suggest that one of these, ahem, gentlemen is you:

But of course I wouldn't, even though you tend to present yourself as one.
