Researchers claim that global warming is turning clear mountain lakes green in western US because of an increase in algae blooms

Researchers at Colorado State University found that the concentration of algae in two remote mountain doubled in the past 70 years

Scientists used a tool called a gravity corer to collect sediment cores without  damaging the lakebed. After which they examined algae concentrations in lakes in a mountain range about 100km from Denver

It is said that the amounts of algae documented in the study would more typically be found in highly polluted areas

Scientists claim that water and marine algae blooms have a huge negative economic impact,  affecting fisheries, tourism and human well being.
