Deaths caused by climate change could rise by century's end: study

Deaths caused by climate change could rise by century's end: study

A new study warns that rising temperatures driven by climate change could cause millions of deaths per year by the end of the century.

This could potentially match the global death rate for all infectious diseases combined, noted the study released by the University of California, Berkeley on Monday, reports Xinhua.

As greenhouse gas levels continue to escalate, rising temperatures in the decades ahead could raise annual global mortality rates by 73 deaths per 100,000 people – almost the same current death rate for all infectious diseases globally, according to the study led by Solomon Hsiang, a climate policy researcher at the UC Berkeley and prepared by the Climate Impact Lab.

The researchers found that even moderate mitigation of emissions that falls short of the Paris Agreement's long-term targets would cut the projected mortality by about 84 percent at the end of the century, relative to a scenario of continued high emissions.

Under this moderate emissions scenario, projections show climate change could be responsible for 11 additional deaths per 100,000 by 2099 – on par with the current fatality rate from auto accidents of roughly 12 deaths per 100,000 in the US.

‘Putting lives at risk’

The world’s poorest people will suffer more, said Michael Greenstone, an economist at the University of Chicago and co-author of the study.

"Our data indicate that with the continued growth of greenhouse gas emissions, the temperature effects of climate change are projected to be five times deadlier than recent US flu seasons," Greenstone said. "In poor, hot countries, the heat may be even more threatening than cancer and heart disease are today."

By dividing the globe into 24,378 regions, the findings identify which places will bear the greatest burden.

Communities that have been exposed to hot climates for a long time are better adapted, the study shows.

It found that elderly populations in the world's richest third of locations are less vulnerable than those in the poorest third of locations, with a hot day above 35 degrees Celsius causing five fewer deaths per 100,000 in the wealthier parts of the world.

Hsiang emphasised that the mortal threat of climate change could no longer be considered an abstraction waiting far in the future.

"Failing to address climate change is not that different from driving your kids around without a seat belt: you are putting their lives at risk," he said.
