Nine crucial tipping points in Earth’s climate are now “active” and in danger of being crossed thanks to warming global temperatures caused by human activity, warn scientists in a commentary published on Wednesday in Nature.
These climate thresholds, such as the decline of ice sheets and loss of biodiverse habitats, could cumulatively trigger a global tipping point that would be “an existential threat to civilization,” cautioned the authors of the article.
“Evidence is mounting that these events could be more likely than was thought, have high impacts, and are interconnected across different biophysical systems, potentially committing the world to longterm irreversible changes,” said corresponding author Tim Lenton, director of the Global Systems Institute at the University of Exeter, in an email.
The nine tipping points that Lenton and his colleagues emphasize fall into two main categories: the loss of the planet’s icy cryosphere and key parts of its living biosphere. The cryosphere thresholds include the melting of Arctic sea ice, the Greenland ice sheet, the West Antarctic ice sheet, and regions of East Antarctica. The biosphere tipping points involve the devastation of boreal forests, the Amazon rainforest, warm-water coral reefs, and the thawing of frozen soil known as permafrost.

Do they know what a “tipping point” is?
I think they use the phrase as “a point I’d rather not get to”.
But I consider a tipping point to be a point beyond which things happen much faster and much more uncontrollably. Will we see that? Any day now? Because if things visibly and incontrovertibly spin out of control next month, a lot of naysayers will be convinced.
But it’s all BS, so there is no “tipping point”.
To be at a tipping point, the process has to be significant and accelerating, and those are all either decelerating or insignificant. The other thing I don't see mentioned this time is the positive tipping points like the greening of the Sahel (and then the Sahara). The greening leads to more rainfall and more greening, causing a tipping point.
One more thing that was noted in the old paper: none of these regional tipping points have any bearing on the planet as a whole. Yes, there was Arctic ice loss back then, but it didn't matter. It still doesn't matter, and like I said, it has leveled off.
What they always leave out is the natural gains and losses and changes. There was more loss of Greenland's ice in the 1920's, based on the retreat of the glacier termination points. There was a huge amount of loss in the mid Holocene (about 5-6000 years ago).
Raise taxes on everybody especially the rich! That will reverse the trend and we all will be saved. //sarc off//
No good has come from all the gimmicks to change the temperature of the earth. It's all about marketing....just like the rabbit food that replaces highly valued Protein in meat and fish.
...the rabbit food ...

And then there are huge recalls of all leafy salad greens. Happening this very week in both groceries in our nearest town. Only 1 box of micro greens to be found in one convenience store. We’ve eaten then 2x so far and we’re fine.
Iceberg lettuce is fine.
Humans have been on the planet six million years...
Look like we make it a lot longer...
More fake news
Change. It is the most natural aspect of Earth. It is and has forever been changing, not static. From all that change, not a forever status quo, all that we see, of the landscape and all that is living has developed. We owe all the earth has today to change, to Life’s response to change.
Life writ large will not vanish due to “climate change”. Neither will we. We will, like Life itself, adapt and mitigate effects of “climate change”.
Call me when the price of waterfront property declines 30%. I’ll hock everything to be a buyer.
Ps: waterfront property is like gold, only better, it is a real asset and it is recession proof. And you can use it or have it produce income , or both.
Islands are tipping everywhere.
They’ll just say they were off a few years and carry on with their insanity to the next generation.
I lost count of how many times they have told us that the “tipping point” was close. You would think that we should have gotten to it in the 40+ years that they have been warning us.
Can we say bull excrement?
My point is just that there is a very significant degree of incest of sorts among the climatology community, and the field desperately needs new thinkers from the outside.
Only if it is solar or wind powered!
Is there a “Pull a Number out of your Ass” Degree Program?
Apparently many Universities offer it.
They were asked about it when exiting a Double Feature of The Day After Tomorrow and Geostorm.
