Extreme weather: the annual number of days with more than 45 degrees has doubled in the last four decades

In the last four decades the number of days of extreme heat per year doubled, and the “burning days are manifested in a greater number of areas of the planet than in the past, presenting unprecedented challenges to human health “, according to a study published by the BBC.

According to the study, the total number of days above 50ºC increased in each of the four decades since 1980.

Between 1980 and 2009, temperatures exceeded 50º C about 14 days per year on average, a figure that increased to 26 days between 2010 and 2019. In the same period, also on average, there were two more weeks a year in which temperatures exceeded 45 degrees.

“The increase can be attributed 100 percent to the use of fossil fuels”said climate scientist Friederike Otto.

According to the research, “as the entire planet warms, extreme temperatures become more likely and more intense.”

The report noted that high temperatures “can be deadly to humans and nature, causing significant problems in buildings, roads and power systems.”

Temperatures of 50 ° C occur predominantly in the regions of Middle East and the Persian Gulf but after record temperatures of 48.8 ° C were recorded in Italy and 49.6 ° C in Canada This summer, scientists have warned that temperatures above 50 ° C will be experienced elsewhere unless we reduce fossil fuel emissions.

“We need to act quickly
. The faster we reduce our emissions, the better off we all are, “warned researcher Sihan Li.” With continued emissions and inaction, these extreme heat events will not only become more severe and frequent, but emergency response and the recovery will be more demanding, “he added.
