Why Are Many of the World’s Largest Lakes and Reservoirs Shrinking Water, This Says Scientists
SERAMBINEWS.COM – Climate change has an impact on large lakes and reservoirs in the world.
Unknowingly slowly the water continues to shrink.
The scientists who conducted the research also revealed the results.
A new study published Thursday (18/5/2023) shows that more than half of the world’s largest lakes and reservoirs have begun to evaporate and shrink since the early 1990s.
Climate change is suspected to be the main cause.

A team of international researchers found that the Caspian Sea between Europe and Asia to Lake Titicaca in South America has been losing water at a cumulative rate of about 22 gigatonnes per year for nearly three decades.
That’s about 17 times the volume of Lake Mead, the largest reservoir in the United States.
Fangfang Yao, a surface hydrologist at the University of Virginia who led the research, said 56 percent of the decline in natural lakes was driven by climate warming and increased human consumption.
“Climate scientists generally think that arid areas in many parts of the world will become drier due to climate change, while areas that are wetter will get wetter.
However, the new study found a significant loss of water volume in humid areas.
This is not to be underestimated,” Yao said.

In this study the scientists observed nearly 2,000 large lakes using satellite measurements combined with climate and hydrological models.
They found that unsustainable human consumption is one of the reasons for the reduced volume of lakes.
