As the climate collapse occurs, water resources problems—drought and its accompanying wildfires and floods—may become more serious worldwide. According to data from the Intergovernmental Panel on Climate Change, global warming may reach at least 1.5 degrees Celsius in the next 20 years. Rising temperatures will be accompanied by huge changes in the earth’s water cycle. The already wet areas become more humid, and the already dry areas are more prone to greater droughts. The report found that for every 1 degree Celsius increase in global warming, extreme rainfall will increase by 7%. As the atmosphere continues to heat up, we expect the hydrological cycle to accelerate: evaporation in the tropics will be stronger, and rainfall in high latitudes and some equatorial regions will be more intense. This will lead to more frequent extreme rainfall events in already wet areas, as well as a greater incidence and severity of flooding.
“There is already strong evidence that we are seeing this change. In some dry areas, droughts will get worse and last longer. Such risks are exacerbated by chain reactions, such as the larger ones we have already seen. Wildfire risk.” Professor Ralph Toumi, co-director of the Grantham Institute for Climate Change at Imperial College London, said: “The principle of world warming is to evaporate more water, which will exacerbate drought, and this increased water in the atmosphere will increase. The amount of rainfall when it rains.” From the United States, where the drought is increasingly serious in the western and southern parts of the United States, to India, where monsoons may become more volatile, the effects are felt globally. Droughts in many parts of sub-Saharan Africa may also intensify, while China and Europe will suffer floods and droughts.
Ilan Kelman, Professor of Disaster and Health at University College London, said: “Climate change will make wet and dry conditions more extreme. In already arid regions such as the Mediterranean and Southern Africa, soil moisture will decrease and dry periods will increase. Seasonal rainfall changes are expected to increase. , The number of rainy days decreases and the intensity of heavy rain increases.” advertise Changes in the earth’s natural rainfall patterns are one of the greatest impacts of the climate crisis. The landmark IPCC report released last week contains more than 200 pages on this issue alone. The expected impact of the climate crisis on water will be discussed more fully in the second part of the report in February next year-this is the sixth report of the world’s climate science authority since 1988-but the findings so far include By far the most obvious warning of these problems is facing the world.
