Climate change tipping points will be passed sooner than thought: Study

[Uncle Joe]

A new study in the journal Science finds that even the most aggressive goals of reducing greenhouse gas emissions aren’t sufficient to avoid several major climate change tipping points, in which rising temperatures cause irreversible damages that in turn cause more global warming.

One of the most worrisome risks of climate change, for example, is that permafrost — a layer of frozen soil in the polar regions — will continue to thaw, releasing planet-warming gases such as carbon dioxide and methane that are currently embedded in the soil. Arctic permafrost alone contains roughly 51 times as much carbon as the entirety of 2019’s global emissions, according to NASA, and if it thaws would speed up global warming at an alarming rate. The last two global climate change agreements brokered by the United Nations have set an aspirational goal of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels, with a fallback goal of 2°C (3.6°F), in order to stave off that kind of catastrophe.

But the new study finds that the permafrost may permanently thaw even if warming stays between the current 1.1°C of warming and 1.5°C, and becomes “likely” if warming falls between 1.5°C and 2°C.

In addition to thawing permafrost, other potential risks include “collapse of the Greenland and West Antarctic ice sheets” and “die-off of low-latitude coral reefs.” If the Greenland ice sheet melts entirely, it could result in 20 feet of sea level rise. Last year a study by the Potsdam Institute for Climate Impact Research in Germany found that 3 to 6 feet of sea level rise from partial melting of the Greenland ice sheet is already likely to occur, though at its current rate it would take centuries. A full-scale collapse of the ice sheet could have a wide array of dramatic consequences, including the disruption of the Atlantic Meridional Overturning Circulation current, a warm band of water that flows to the northeast across the Atlantic Ocean, which would cause much colder winter temperatures in Europe.

1. K n R ! Thanks for posting!

Important info Uncle Joe!

2. Joe, I'm afraid the light ahead is not the end of the tunnel

3. I know...

...i end up in tears at least once a day thinking of how my babies, grand-babies and babies all over the world will suffer before they die.

4. Then we can select trump after all

We're going to die anyway.

[Kaleva]

8. The chances of dying are reduced if one is proactive and prepares

Those who are reactive,, for whatever reason, have a higher chance of dying.

5. Anyone with an triple digit IQ

has observed this for years. It is so obvious that you don't need a scientist to prove it with data. Just use your own memory, if still intact, to notice the many, many changes in the past 10-20 years. It is glaringly obvious. Nothing will be done that can change this course at this point since no one who can do something is allowed to do something by the $$$$$$ and powers that be...the US and other countries are too greedy to give a shit and this will NEVER change. Death and destruction will be accepted and excuses will be made for their agenda.

Humans love to kill each other and animals.. Humans are greedy. It is the Humans who will harm their own species...all for $$$ and power. This is who we are and always will be. Humans/governments will "adapt" and pour big $$$$ into attempting to change courses but we all know they do NOT give a shit and never will...it would be for show/PR as it has been for decades. They DO NOT CARE and they never will. "Fuck the future of humanity...let's rake in the big $$$$$$ now and leave the ruins to future generations" is their motto. Big $$$ rules, not human life.

7. Few want to adapt a net zero emissions life style

Even if we could reduce emissions to zero, some greenhouse gases can remain in the atmosphere for hundreds of years

9. I wonder if there are DUers living in coastal areas who will be moving soon

Or have already moved.
