MIT: Climate tipping point, minimum 152°F before runaway greenhouse effect kicks in

[cancel2 2022]

Current trend of “global warming” isn’t enough to get there, says MIT scientist. How Earth sheds heat into space New insights into the role of water vapor may help researchers predict how the planet will respond to warming. Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises.

Just as an oven gives off more heat to the surrounding kitchen as its internal temperature rises, the Earth sheds more heat into space as its surface warms up. Since the 1950s, scientists have observed a surprisingly straightforward, linear relationship between the Earth’s surface temperature and its outgoing heat.

But the Earth is an incredibly messy system, with many complicated, interacting parts that can affect this process. Scientists have thus found it difficult to explain why this relationship between surface temperature and outgoing heat is so simple and linear. Finding an explanation could help climate scientists model the effects of climate change.

Now scientists from MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS) have found the answer, along with a prediction for when this linear relationship will break down.

They observed that Earth emits heat to space from the planet’s surface as well as from the atmosphere. As both heat up, say by the addition of carbon dioxide, the air holds more water vapor, which in turn acts to trap more heat in the atmosphere. This strengthening of Earth’s greenhouse effect is known as water vapor feedback. Crucially, the team found that the water vapor feedback is just sufficient to cancel out the rate at which the warmer atmosphere emits more heat into space.

The overall change in Earth’s emitted heat thus only depends on the surface. In turn, the emission of heat from Earth’s surface to space is a simple function of temperature, leading to to the observed linear relationship.

Their findings, which appear today in the Proceedings of the National Academy of Sciences, may also help to explain how extreme, hothouse climates in Earth’s ancient past unfolded. The paper’s co-authors are EAPS postdoc Daniel Koll and Tim Cronin, the Kerr-McGee Career Development Assistant Professor in EAPS

Good article, not difficult to understand.
Unfortunately the usual suspects are incapable of understanding it and will say the authors are flat earthers. If they bothered to look at the authors' CV's they'd find both have impressive publications.
All the usual Apocolyptic Anthropogenic Sky Ts Falling Chicken Littles are capable of understanding is a Hollywood feature film produced by a simpleton screw ball wacko who got a 'D' in general science in college.
They'll parrot, "Increased input of C in the atmosphere causes increased temp which leads to (gasp) hurricanes ".

And just in case they attack the messenger here's another link:

More food for thought!

just wait until the world's permafrost starts rapidly melting..........a MUCH worse greenhouse gas methane will escape, smashing all linear global warming models to hell

btw worldwide carbon emissions into the atmosphere are still increasing

I know, I know. We heard that 20 yrs. ago. https://www.nytimes.com/1998/08/18/s...ska-melts.html

Tell that to the signatories of the Paris Agreement. The U.S. is doing it's part - without regulation.

Yes, The U.S. Leads All Countries In Reducing Carbon Emissions https://www.forbes.com/sites/rrapier.../#4935518d3535

Theres always yet another scary scenario, once all the others have been shot down in flames.

Climate Alarmism is nothing new, even in 1923 there were people claiming the Arctic ice would disappear.
