Experts warn: heat waves will intensify in the coming years | Sciences

The geographic areas that experience the strongest heat waves are not necessarily those where people and nature are the most degraded, what really matters is the difference between extreme heat waves and average temperatures.

Experts from the Intergovernmental Panel on Climate Change (IPCC), who closely monitor climate development, have announced more and more heat waves in the coming years.

And the French newspaper “Le Point” (Le Point) says in a report that on January 13, 2022, the world temperature record was broken on Earth in Onslow, western Australia, with 50.7 degrees Celsius, noting that we all know that our planet is warming a year. A year later, with no real global mobilization in place, members of the Intergovernmental Panel on Climate Change, which relies on the United Nations, are threatening hell on Earth as heat waves intensify.

And the newspaper indicated that the Indians recently suffered from a severe heat crisis, as last March was the hottest month in 120 years. In the last half of the previous April, temperatures rose from the normal range by 4.5 to 8.5 degrees Celsius.

Last summer, North America suffered a severe heat wave with a record 49.6 degrees Celsius in Leighton, British Columbia, in Canada, as reminds us of the recent Australian droughts that were accompanied by extreme temperatures.

temperature records

However, the newspaper says that a study published by climatologists at the University of Bristol in the journal Science Advances states that these heat waves are not the worst in decades, as other events have occurred and have not been announced much. for two reasons; First, because it swept through the lesser-known countries, and secondly, because the intensity of the heat wave should not be estimated in absolute terms, but rather taking into account the local temperature.

The newspaper explains that the study highlighted the record heat waves that hit Southeast Asia in April 1998, which peaked at 32.8 degrees Celsius, and the heat waves that swept Brazil in November 1985 at 36.5 degrees Celsius, and those in the southern states in July July 1980 at 38.4°C.

“It is important to assess the intensity of heat waves in terms of local temperature fluctuations that humans will encounter. Thus, in regions where temperature differences are less severe than elsewhere, a heat wave, no matter how intense, can,” stressed the study’s lead author, Vicki Thompson. to cause more harmful effects.

In general, with equal heat waves, the consequences will be more harmful. She pointed out that the geographic areas that experience the strongest heat waves are not necessarily those where people and nature are the most degraded, indicating that what really matters is the difference between extreme heat waves and average temperatures.

This is indicated on the surface of the globe with a color code showing the magnitude of the maximum temperature since 1950 in each region. Thus, in France the heat waves are 3 ° C, while in Spain it is less than 2.5 ° C.
