The study says that by 2022, global warming will alter the water cycle

for the third consecutive year, no nina Exacerbated droughts in the Americas and caused flooding in parts of Asia and Oceania. An unprecedented report was released this Wednesday, 11th, by World Water Watch Association I found that Global Warming make a change Water Cycle in a planet. The Australian National University survey also warns that events such as sudden dehydration It will become more frequent in the coming years.

The group collected water measurements from thousands of ground stations and satellites to produce up-to-date information on precipitation, air temperature and humidity, groundwater, river flows, and water volume in natural and artificial lakes. In 2022, the water cycle is dominated by relatively warm ocean waters in the western Pacific and eastern and northern Indian oceans. As a result, a severe heat wave developed in South Asia at the beginning of the year, followed by a very wet monsoon that caused massive floods in Pakistan.

Elsewhere, in Europe and China, extreme heat waves have triggered so-called “sudden droughts,” which occur within a few months of extreme heat waves, causing reduced river flows, damage to agriculture and wildfires.

The report shows that the air temperature over land in 2022 followed a long-term warming trend, while air humidity is declining. “This means that nature, crops and people will need more water to stay healthy, exacerbating the problem,” said Professor Albert van Dyck of the Australian National University, lead author of the study.

2022 was the third consecutive year of La Niña. This caused flooding in Australia and exacerbated drought conditions in the western United States and parts of South America. In Brazil, for example, heavy rains have caused floods and landslides. “Whether these three La Niña years are just a statistical fluke or the first signs of something more sinister,” said Professor Van Dyck. “If La Niña or El Niño patterns persist much longer in the future, it will cause a lot of problems, with worse and worse droughts and worse floods.”

The report also provides an outlook for 2023, with relatively dry conditions indicating the potential for intensification or development of droughts in parts of North and South America, Central Asia, China and the Horn of Africa. However, La Niña conditions are decreasing, so there is hope that water availability will soon return to more normal levels in some of these areas.
