(ORDO NEWS) — A global study based on data from more than 36,000 weather stations around the world confirms that as the planet continues to heat up, extreme weather events, such as heat waves and heavy rains, have become more frequent, more intense and longer.
The study is based on a dataset known as HadEX and analyzes 29 extreme weather indexes, including days above 25 or below 0, and consecutive dry days with less than 1 mm of rainfall. This latest update compares three decades between 1981 and 2010 with 30 years earlier, between 1951 and 1980.
In general, the index shows an increase in the number of warm days above the average. This increase in extreme temperatures can have devastating effects on human health, especially for older people and people with pre-existing conditions.
Excessive heat is a problem not only for people living in cities, but also for rural residents who have already been exposed to days with temperatures above + 50 °.
One thing is clear that extreme temperatures and precipitation can have very dramatic consequences, as, for example, two sea waves of heat in New Zealand and the hottest and driest year in Australia in 2019 indicate.
