Lakes on Tibetan Plateau Freezing Late, Melting Early: Study

The lakes on the world’s highest plateau showed a trend of delayed freezing and melting that took place earlier than usual over the four decades up until 2017, a new study found, underscoring the impact of climate change on some of the planet’s most vulnerable regions.

Around four-fifths of the 132 lakes monitored on the Qinghai-Tibet Plateau saw the length of time they were covered by ice shortened by a certain period ranging from a few days to over 50 days between 1978 and 2017, according to the study published Friday. It was published in Scientific Data, Nature’s open access scientific journal, by researchers from the state-backed China Academy of Sciences.

Known as Asia’s “water tower,” the Tibetan Plateau is home to many glaciers and lakes. It is the source of 10 major rivers in Asia, providing water supply to almost 2 billion people.
