A recent study found that the Earth is facing five catastrophic climate tipping points, and that the failure to achieve the Paris Climate Agreement goal of limiting global warming by 1.5 degrees Celsius.
The study, published in the journal Science, states that “even current levels of warming have already put the world at risk of five major tipping points – including the collapse of the Antarctic and Greenland ice sheets – but it is not too late to change course,” he asserts. authors.
“What I’m thinking is that these shifts, if they happen, could change the face of the world (…) due to the long-term rise in sea levels, the death of rainforests and so on,” senior author of the study, Tim Linton, from the University of Exeter, told AFP.
Linton authored the first major paper on tipping points in 2008, and warns that if pollution and emissions are not controlled and brought to a halt, then “if warming stops, the ice sheet, ocean, or rainforest may continue to change.”
Early assessments indicate that these points will be reached within 3-5°C of warming, and there may be “a collapse of the Greenland and West Antarctic ice sheets, sudden widespread thaw (…) or death of tropical coral reefs.”
Linton warned that if the ice sheets in Greenland and West Antarctica melt, the global sea level may eventually rise by ten meters, but that this may take hundreds of years, according to the “Science Alert” website.
