Climate change is having a widespread effect on lakes across the Northern Hemisphere, a new study has found.
The study, published in the journal Geophysical Research Letters, examined 122 lakes from 1939 to 2016 in North America, Europe and Asia, and found that ice-free years have become more than three times more frequent since 1978.
These ice-free years not only threaten the livelihoods of people who depend on them, but they also have the potential to cause deep ecological impacts.
“Ecologically, ice acts as a reset button,” said Sapna Sharma, co-author of the study and an associate professor in the biology department at York University in Toronto.
