Climate change is causing the planetary water cycle to accelerate, altering the salinity of oceans, lakes and rivers. With each degree of warming gained, the risks of droughts and torrential rainfall are multiplied.
Satellite data reveals a worrying shift inEarth’s global. The water cycle is the course that takes place naturally between the great water reservoirs of our planet. L’ of and the are at the origin of this course, by favoring the evaporation of water and its displacement in the atmosphere.
L’. The forecasting models of had already considered this phenomenon, but not so quickly. the greater the evaporation from the surface of the oceans, which leaves surface waters saltier and adds additional moisture to the atmosphere.becomes more and more fresh and salty water becomes more and more salty, this is the finding of a study by Spanish researchers from the Institute of Marine Sciences
More droughts or more floods depending on the region
This humidity will increase precipitation in certain regions of the world, and dilute the fresh water in rivers and lakes, making them even less salty. This development could also supercharge episodes of torrential rainfall. Wetlands will therefore be even wetter, with more intense and frequent rainfall leading to more flooding, and drylands will suffer even more from drought. A quarter of humanity already suffers from lack of water, and the prospect of . In the polar regions, the has already resulted in increased rainfall in the spring, melting the snow even faster.more frequent and stronger could lead to an unprecedented planetary crisis,
The water cycle speeds up by 7% for each degree it increases
Climate change also results in . Concretely, this means that wet areas will be 7% wetter, and dry areas will be 7% drier. Estimates that agree with on the envisaged consequences of climate change: if humanity manages to limit the rise in temperatures to 2°C compared to pre-industrial levels (knowing that we are already at 1.2°C), the will be 14 times stronger anyway compared to what they were at the beginning of the industrial revolution.from . These less strong winds allow the surface waters to warm up, without allowing the hot surface water to mix with the cooler water below: the surface waters evaporate and the salt therefore remains trapped on the upper level. The most recent climate prediction models estimate that for each degree of warming gained, the
