U.S. Could Get Very Hot
Climate crisis: US ‘on path to extreme heat’ in coming decades if emissions aren’t reduced, study says; Only mountainous regions will remain extreme heat refuges in 80 years if current emissions levels continue, scientists warn
Harry Cockburn, July 16, 2019 (UK Independent)
“…By 2050, hundreds of American cities could experience an entire month each year with US ‘heat index’ temperatures above 100F (38C) if nothing is done to tackle emissions and the resultant climate crisis…[According to new research from the Union of Concerned Scientists,] the US National Weather Service heat index scale starts topping out above temperatures of 127F (52C), depending on the combination of temperature and humidity…[O]nly a few mountainous regions would remain extreme heat refuges by the century’s end…[A failure to reduce emissions could set the country on a path] so far in excess of current climate trends they will surpass the heat index…
…[The index] is a measure of how hot it feels when humidity is factored in with the air temperature…[Its coloured scale starts] with 80F (26C) which is yellow – caution, and rising through dark yellow beginning at 91F (33C) – extreme caution, orange at 103F (39.5C) – danger, and up to red beginning at 126F (52C) – extreme danger…The average number of days per year nationwide with a heat index above 105 degrees Fahrenheit would more than quadruple to 24 by mid-century and increase eight-fold to 40 by late century…Such ‘off-the-charts’ conditions could pose unprecedented health risks…” click here for more
