One in 10 people around the world will live in a place where climate change is damaging at least two major sectors such as crop yields, water, ecosystems or health, said an international study on Monday.
These so-called climate “hotspots” will be most widespread in the southern Amazon, with “severe changes” in water availability, yields and ecosystems, said the study in the Proceedings of the National Academy of Sciences, a US journal.
The second largest hotspot region is southern Europe, where water shortages and crop failures would lead to hardships for the population, said the study led by Franziska Piontek of Germany’s Potsdam Institute for Climate Impact Research.
“Overlapping impacts of climate change in different sectors have the potential to interact and thus multiply pressure on the livelihoods of people in the affected regions,” said Piontek.
The study included climate impact researchers from Japan, the United States, China, Europe and beyond, and used mathematical modeling programs to project how global warming will change the livelihoods of people around the planet.
Different levels of warming were analyzed, with multi-sector overlap beginning to appear “robustly” at an average warming worldwide of three degrees Celsius above the 1980-2010 average, it said.
When that figure was raised to four degrees Celsius above the 1980-2010 average, 11 percent of the world’s population was “subject to severe impacts in at least two of the four impact sectors,” it said.
Other hotspots included tropical regions of Central America and Africa, as well as the Ethiopian highlands because of the overlapping pressures of malarial spread, suffering crops and ecosystem changes.
Northern regions of south Asia were also predicted to suffer because of crop woes combined with either ecosystem changes or water availability.
“What today is considered extreme could become the new normal,” said co-author Qiuhong Tang of the Chinese Academy of Sciences.
The analysis found no place on Earth where all four sectors would experience a severe change.
Much of Africa, which might be considered a vulnerable part of the planet, did not appear as a hotspot under the model methods used. However, the case might be different if droughts and floods were included as metrics, the authors said.
Researchers said the data should help nations plan for significant changes in the decades ahead, either by speeding adaptation strategies or motivating decisions to curb climate change.
“It allows for a risk management perspective,” said co-author Alex Ruane of the NASA Goddard Institute for Space Studies.
“In the hotspot parts of Africa, for instance, even small temperature rises can lead to additional losses that many small farmers simply cannot afford.”
‘It’s treachery if not treason’: Harvard’s Laurence Tribe destroys Trump’s claim he’s above the law
Legendary constitutional law expert Laurence Tribe explained the legality of President Donald Trump's claim to be above the law during a Thursday evening appearance on MSNBC's "The Last Word" with Lawrence O'Donnell.
The host played a notorious clip of Trump.
"I could stand in the middle of Fifth Avenue and shoot somebody and I wouldn’t lose any voters. Okay? It’s like incredible," Trump argued.
"And now he has gone beyond that," O'Donnell noted. "Now the president is sayin, 'I could stand in the middle of Fifth Avenue and shoot someone and I cannot be prosecuted for that crime. Or any crime.'"

Maddow is visibly shocked Trump is claiming in court the president can’t even be investigated
The host of "The Rachel Maddow Show" on MSNBC was flabbergasted by the latest court moves by President Donald Trump as he continues to hide his tax returns from investigators.
The host noted the ongoing legal battle Trump is waging to keep his accounting firm, Mazars, from handing over eight years of his tax returns to New York state investigators.
The host was shocked by the headline on the front-page of The Washington Post website.
