If global warming persists, blue lakes worldwide are at risk of turning green-brown, according to a new study which presents the first global inventory of lake color. Shifts in lake water color can indicate a loss of ecosystem health. The new research was published in Geophysical Research Letters.
The researchers used 5.14 million satellite images for 85,360 lakes and reservoirs around the world from 2013 to 2020 to determine their most common water color.
Additionally, the new study explored how different degrees of warming could affect water color if climate change persists. The study finds climate change may decrease the percentage of blue lakes, many of which are found in the Rocky Mountains, northeastern Canada, northern Europe and New Zealand.
"Warmer water, which produces more algal blooms, will tend to shift lakes towards green colors," said Catherine O'Reilly, an aquatic ecologist at Illinois State University and author of the new study.
While prior studies have used more complex and finer scale metrics to understand overall lake ecosystem health, water color is a simple yet viable metric for water quality that can be viewed from satellites at the global scale, the authors said. This approach provides a way to study how remote lakes are changing with climate.

““Climate change” is a giant hoax...”
And that stupidity is proven with the article.
Water is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. Water may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water. So the only way for water to change it’s natural use of light and colors is if they cease to exist. And climate change cannot erase color.

The Junk Scientists are on Junk
A deep brown bovine excrement.
Establishment science has become totally subservient to politics. The corruption is all encompassing.
Water is clear, not Blue.
And it’s making communists more red.
Water is colorless. Lakes and whatever water body reflects the color of the sky.
Tell it to the sun, you corrupt scientists.
