In recent decades, tens of thousands of people around the world because of extreme heat have died, but the phenomenon is the deadly heat would be easy to miss. This can not be true much longer. would be a new analysis published this week by the National Bureau of Economic Research suggests that if left unchecked, temperatures of climate change to the point where going lead to 85 deaths per 100,000 people per year worldwide by the end of the century, This is to be greater than the current one killed from all infectious diseases around the world. “We are doing a lot of things in the world, health improve quickly,” says Solomon Hsiang, a professor of public policy at the University of California, Berkeley, and one of the authors of the new paper authors. “Climate change would be a huge step back on this progress.” The document is formally a “working paper” and has not undergone peer review, but a reality that quantifies the researchers that climate change aimed at long study. People fight to survive in extreme temperatures, and this challenge will only get worse as the increase in global average temperatures. Even today, many people especially the elderly are vulnerable adults. 2015 heat wave in India and Pakistan, for example, killed more than 3,000 people. is the new research suggests a rise of increasingly important burden on the health system temperature, doctors force an increase in heat-related illnesses in coming decades to fight. Some places will handle these challenges better than others. Already, the vulnerability to extreme heat is not evenly distributed, with poor communities the most vulnerable and poorest countries to the problems than their wealthier counterparts heat-related. The new study shows that inequality will continue over time: some of the worst remote villages, now might be a high mortality rate as 160 per 100,000 people reached. At the other end of the scale, countries, and now cold climate zones-that can afford to adapt the study will show in Europe will probably lower rates year to see death, thanks to warmer temperatures are in fact the North, in the first place. Other rich countries are still facing a mortality peak, but its economic resources, will help cushion the impact. “A lot of pain for rich people is through their wallet,” says Hsiang. “In the poorest, hot spots, people will die.” The study has important technical and political implications. For years, economists and politicians have tried to bring about a “social cost of carbon emissions”, that a ton of carbon emissions quantified the economic value of prevention. The Obama administration is calculated at about $50; Trump is suggesting that the government has estimated to be $1 ° This new study finds that carbon social cost is $37 for the only deaths related to heat. But this is just the tip of the iceberg. If you consider the cost of hurricanes, floods and climate Migration, as well as a number of other challenges, the study suggests that carbon social cost is probably much higher, and should therefore be to act much greater urgency. These results all underscore a familiar conclusion: act now to tackle climate change save lives and dollars in the long Photo copyright period Georges Gobet AFP / Getty Images.
