Even if humanity somehow manages to contain global warming as much as possible, several Earth-changing climatic "

In particular, this is the irreversible collapse of the Greenland Ice Sheet.. The planet will continue to heat up more and more, according to a new study, which writes AssociatedPress science author Seth Borenstein.

An international team of scientists looked at 16 climate tipping points — when warming becomes irreversible, self-sustaining and massive — and calculated the approximate temperature thresholds at which they are triggered..

At current temperatures, most of these thresholds or points of no return have not yet been passed, although some of them are already very close.. So, with a warming of 1.5 degrees Celsius since pre-industrial times, four of the “points of no return” will become very likely.

The study says the slow but irreversible destruction of the Greenland and West Antarctic ice sheets, the accelerating loss of tropical coral reefs around the world, and the melting of northern permafrost, which releases huge amounts of greenhouse gases, are four tipping points that could be passed with warming.

According to some projections, current policies and actions have put the Earth on a warming trajectory of about 2.7 degrees Celsius since pre-industrial times..

" “However, there is a strong possibility that some of these tipping points are inevitable.”. And so it is very important that we think more about how we will adapt to the consequences."

Timing is a key issue for tipping points in two respects: when they work and when they cause damage.. In many cases, such as when an ice sheet breaks, they can work in the near future, scientists say, but their consequences, even if inevitable, will be manifested for centuries.. Some of them, such as the death of coral reefs, do more harm in just a decade or two..

" "

The concept of tipping points has been around for more than a decade, but this study goes further, looking at temperature thresholds, when they can be triggered, and what impact they will have on people and the Earth, and over the last 15 years or so, “risk levels continue to rise.”.

Study co-author Johan Rockstrom, director of the Potsdam Institute for Climate Impact Research in Germany, compared it to someone lighting a fuse on a bomb, "

While ice sheets with potential sea rises of several meters could change the shape of coastlines over the course of centuries, Rockstrom said that for him the loss of coral reefs is of greatest concern because of the " Hundreds of millions of people, especially the poor in tropical areas, depend on coral reef fisheries.

A few more tenths of a degree and new tipping points will become more likely, including a slowdown in the circulation of the Arctic Ocean, which could lead to dramatic weather changes, especially in Europe, the loss of some Arctic sea ice, the collapse of glaciers around the world and the complete disappearance of the Amazon rainforest..

Some of these hotspots, such as melting permafrost, amplify and accelerate existing warming, but don't think it's "

“Even if we reach some of these tipping points, it will still lead to really significant consequences that we want to avoid, but this will not start some kind of catastrophic process of climate change,” McKay said.. " And that means it's still within our power to stop further warming beyond 1.5 degrees."

This is a very important point because we are talking about tipping points for individual regional catastrophes, not for the planet as a whole, so it's bad, but not the end of the world, said climate scientist Zeke Hausvater of the technology company Stripe and Berkeley Earth, who was not involved in.
