Being Outside Could Become Deadly In South Asia, Says Study (go.com)
An anonymous reader quotes a report from ABC News: Venturing outdoors may become deadly across wide swaths of India, Pakistan and Bangladesh by the end of the century as climate change drives heat and humidity to new extremes, according to a new study. These conditions could affect up to a third of the people living throughout the Indo-Gangetic Plain unless the global community ramps up efforts to rein in climate-warming carbon emissions. Today, that vast region is home to some 1.5 billion people. While most climate studies have been based on temperature projections, this one -- published Wednesday in the journal Science Advances -- is somewhat unique in also considering humidity as well as the body's ability to cool down in response. Most of those at risk in India, Pakistan and Bangladesh are poor farmworkers or outdoor construction laborers. They are unlikely to have air conditioners -- up to 25 percent in of India's population still has no access to electricity. In some areas that have been deforested for industry or agriculture, they may not even have very much shade.
For the study, the researchers carried out computer simulations using global atmospheric circulation models under two scenarios -- one in which the world comes close to meeting its goal of curbing emissions to limit Earth's average temperature rise to 2 degrees C (3.6 degrees F) above pre-industrial levels, and one in it continues emitting at current levels. Both scenarios play out dangerously for South Asia. But with no limit on global warming, about 30 percent of the region could see dangerous wet bulb temperatures above 31 degrees C (88 degrees F) on a regular basis within just a few decades. That's nearly half a billion people by today's population levels, though the full scale could change as the population grows. Meanwhile, 4 percent of the population -- or 60 million in today's population -- would face deadly highs at or above 35 degrees C (95 degrees F) by 2100. But if the world can limit global warming, that risk exposure declines drastically. About 2 percent of the population would face average wet bulb temperatures of 31 degrees C (88 degrees F) or higher.

The summary says two emissions scenarios were looked at " one in it continues emitting at current levels". The article says RCP 8.5 was used. RCP 8.5 is quite incredible. Nigeria has a current population of 200 million. Under RCP 8.5 it is envisaged that this will grow to 1.5 billion by the end of the century, turning a rural country into one with the same population density as the Vatican Cty.
Also of course, TFA relies on the same sort of computer models that have currently been overpredicting temperature rises consistently since 1990.
Plus also overpopulation is a problem. Let them die I say, they're not furthering humanity's progress anyway. It'll make space for us to actually make use of their resources rather than just sit on them.
That's the general attitude here. On /., and the west in general. Who gives half a fuck about Indians? There's so many of them anyway, a few million of them dying, so what? I got my air condition, I got my office job, why should I not continue driving my SUV just so some Indian pariah can survive?
