Not exact matches

Under this scenario, the new study finds that 4 percent of the South Asian population would experience deadly wet - bulb temperatures exceeding 35 ° C. Approximately 75 percent of the population would experience humid temperatures higher than 31 ° C, which are dangerous for most humans, but rarely reached right now, Pal and colleagues report.

In South Asia, the highest daily wet - bulb temperatures, which include both heat and humidity, have been recorded around the Persian Gulf and Red Sea, the Indus and Ganges river valleys and eastern China.

The new analysis is based on recent research showing that hot weather's most deadly effects for humans comes from a combination of high temperature and high humidity, an index which is measured by a reading known as wet - bulb temperature.

The researchers also looked at the changing likelihood of «extremely warm summers,» defined as the real - world summer in each region with the highest average wet bulb globe temperature between 1973 and 2012.

Given that impacts don't scale linearly — that's true both because of the statistics of normal distributions, which imply that (damaging) extremes become much more frequent with small shifts in the mean, and because significant breakpoints such as melting points for sea ice, wet - bulb temperatures too high for human survival, and heat tolerance for the most significant human food crops are all «in play» — the model forecasts using reasonable emissions inputs ought to be more than enough for anyone using sensible risk analysis to know that we making very bad choices right now.

I suspect that although currently the probability of lethal wet bulb temperatures, or catastrophic rain events are very low, because of the shapes of the curves and «the Statistical parameters are surprisingly predictable, and weather statistics is systematically influenced by the physical conditions present» that their relative increase and risk are much higher than most people appreciate.

Today, the summer temperature varies widely over the Earth's surface, but wet bulb temperature is more narrowly confined by the effect of humidity, with the most common value of approximately 26 — 27 °C and the highest approximately of 31 °C.

Researchers for the first time have calculated the highest tolerable «wet - bulb» temperature and found that this temperature could be exceeded for the first time in human history in future climate scenarios if greenhouse gas emissions continue unabated.
