The greatest concern of the experts focuses on the high temperatures that plague South America in “its supposed winter”.
The heat waveswhich currently affect Europe and other regions of the North Hemisphere, their intensity and duration increase more and more. Even in certain areas could become a freak permanent due to climate changealerted a specialist from the United Nations Organization (UN).
The “heat dome” (a phenomenon that, due to the stagnation of the air masses, warms the atmosphere) that covers a large part of Europe, the forest fires caused by the drought suffered by Greece, Spain, Portugal, Canada and Hawaii, or the high temperatures in the middle of the South American winter are the direct consequences of global warming that affects the world in recent times.

“Heat waves will become increasingly intense and frequent. It is the consequence of global warming that we see appearing very quickly in weather systems.“he told AFP. john nairnexpert in extreme heat of the World Meteorological Organization (WMO).
The expert regretted that the scientists warned about this phenomenon:”People are too relaxed about the signs“. Nairn recommends focusing attention on the incessant increase in nighttime minimumsand not in daytime heat records.
Elevated and repeated night temperatures are especially dangerous for human health because the body is unable to recover from the heat suffered during the day. Higher overnight lows they also mean that the energy accumulated during the day has nowhere to be evacuated, further increasing the temperatures of the following day.
We thus arrive atlonger periods of elevated temperatures”commented the scientist, assuring that the situation threatens to get worse.

Record temperatures in South America
The situation in regions such as South America is the one that worries specialists the most, which reached heat records in recent weeks, with temperatures up to 40ºC in its supposed winter.
In the future “we will see more heat waves in a much longer period of the year“.
While in the tropical and subtropical regions, “everything indicates that severe and extreme heat waves threaten to occur at any time before the end of the century“.
When asked about a possible solution to this advance, Nairm estimated that “we all have the ability to reverse the trend“.”You have to bring everything to electricity (…) and stop burning fossil fuels. It doesn’t have more complexity than that.“, he explained.
