Rise in lake temperature can lead to harmful algae blooms: Report
Researchers through a newly conducted study have warned that rise in temperature in lakes will give rise to harmful algae blooms and the conditions will worsen with time. It will also lead to low-oxygen zones that will be hazardous to fish.
The researchers, after analyzing 235 lakes that hold more than half the earth’s fresh surface water, found that these lakes have warmed at an average of 0.61 degrees Fahrenheit or 0.34 degrees Celsius per decade.
The report suggests that increase in lake temperature is far higher than those recorded in the oceans or atmosphere. The researchers are worried that such a dramatic rise can highly affect aquatic ecosystem.
It has even raised concerns about the quality of water that people consume and use for a variety of purposes like drinking supplies, crop irrigation and energy production.
Study lead researcher Catherine O'Reilly, an Illinois State University geologist, said, “The message we're getting from our lakes is that they're getting more and more stressed. With these rates of warming, the problems we're seeing will become increasingly common”.
The results of the project funded partly by NASA and the National Science Foundation were made public this week during a meeting of the American Geophysical Union in San Francisco.
The study was based on a first-of-its-kind combination of temperature data collected from satellites and ground measurements for over a period of 25 years. The findings of the study are being published in the group's journal, Geophysical Research Letters
