When temperatures go above 95 degrees
, humans have to sweat to maintain their ideal body temperature but when at the same time the humidity exceeds 75%
or so, this is no longer possible. One of the Earth Institute study authors told CNN,
“I was astonished by our findings…My previously published study projected that these conditions would not take hold until later in the century…”We may be at a closer tipping point than we think.” The author, Radley Horton of Columbia University says
,”[c]limate change is increasing both air temperatures and the amount of moisture in the air, making humid heat events more frequent and severe.” In particular, in the U.S., New Orleans and Biloxi, Mississippi have experienced extreme conditions dozens of times along with cities along the Florida Panhandle and also in eastern Texas.
