Lake heatwaves to increase due to climate change
Lake heatwaves – periods of extreme warm surface water temperature in lakes – may become hotter and longer by the end of the 21st century, according to a new study published in Nature, increasing the link between climate change and extreme events.
The modelling study, which is validated using satellite observation records generated by ESA’s Climate Change Initiative, shows that under a high greenhouse gas emissions scenario, the average duration of lake heatwaves could increase by around three months on average, with some lakes reaching a permanent heatwave state.
The increasing frequency of marine and land heatwaves has been linked to global warming in previous studies. However, less is known about lake heatwaves and how they will be affected by global warming.
