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.”
Mayors rush to impose curfews as civil unrest rocks cities from coast-to-coast
Minneapolis was the first to impose curfews designed to prevent protests of police violence after Mayor Jacob Frey imposed a curfew on Friday.
On Saturday other cities followed suit, with Seattle Mayor Jenny Durkan imposing a curfew set to start only 14 minutes after her announcement.
Los Angeles Mayor Eric Garcetti has issued a curfew for downtown LA.
Protesters give Donald Trump a one-finger salute as Marine One flies over DC protests
President Donald Trump returned to Washington, DC on Saturday as large crowds of protesters fill the city's streets.
Trump had flown to Florida to see the launch of the SpaceX Starship and returned as the sun was going down.
BuzzFeed News reporter Ellie Hall captured a picture of Marine One approaching the White House -- and being welcomed back to town with raised middle fingers.
Trump, in Marine One, just did a flyover of the protest area outside the White House.
Trump announces he has unilaterally decided to let Putin back into the G7 Summit: report
President Donald Trump announced on Saturday that he intends to let Russia attend the next Group of Seven summit.
Since 2014, Russia's membership in the organization has been suspending in response to Vladimir Putin's annexation of Crimea. That changed the name from the G8 Summit to the G7 Summit.
The announcement came from pool reporter Gabby Orr of Politico, who said Trump will also invite South Korea, Australia and India to the next summit, which he is postponing until September.
More via pooler: “‘I don’t feel that as a G7 it properly represents what’s going on in the world. It’s a very outdated group of countries,’ he said. Alyssa Farah said this is bringing together our traditional allies to talk about how to deal with the future of China.”
