শুকিয়ে গেছে বিশ্বের অর্ধেকের বেশি জলাশয় | Lakes Drying | Water Crisis | Researchers | M & S Talks

Over half of the world's lakes have shrunk, according to a new study published on Thursday.

An international research team published their findings in the journal Science and found global warming and human activity to be the chief culprits.
The team of experts said some of the world's critical freshwater sources had lost water at a cumulative rate of around 22 gigatonnes per year for nearly three decades.

"More than half of the decline is primarily attributable to human consumption or indirect human signals through climate warming," said Yao who pointed out that warming contributed "the larger share of that."

The team measured the change in water levels in nearly 2,000 of the world's lakes and other water bodies and based the report on satellite data collected between 1992 and 2020.

In the United States, Lake Mead lost two-thirds of its water during the 28-year period.

The study also found that unsustainable human use dried up lakes including the Aral Sea in Central Asia.

Lakes in Afghanistan, Egypt and Mongolia were hit by rising temperatures, which led to increased rates of surface evaporation.

Scientists said it is necessary to limit global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) to avoid the consequences of climate change. The world is currently warming at a rate of around 1.1C (1.9F).
