Lakes around the world are warming “rapidly” due to climate change threatening freshwater supplies and ecosystems.

That’s according to a new study from NASA funded by the National Science Foundation, which analysed 235 lakes around the Earth.

It found they are warming at an average of 0.61° Fahrenheit (0.34°C) every 10 years.

If this rate continues, emissions of methane will increase by 4% in the next decade, the report added.

This is greater than the warming rate of both the ocean and the atmosphere and it can have “profound” effects.

As warming rates increase in the next century, algal blooms, which can rob water of oxygen are expected to increase by 20% in lakes.

Those which are toxic for fish and animals could increase by 5%.

Stephanie Hampton, Co-author of the report said: “Society depends on surface water for the vast majority of human uses. Not just for drinking water but manufacturing, for energy production, for irrigation of our crops. Protein from freshwater fish is especially important in the developing world.”

Last weekend, 195 nations agreed to work together to combat climate change and keep the global temperature rise well below 2°C at the COP21 conference in Paris.
