Climate warming and heat waves are accelerating global lake deoxygenation, study finds

Freshwater ecosystems require adequate oxygen levels to sustain aerobic life and maintain healthy biological communities. However, both long-term climate warming and the increasing frequency and intensity of short-term heat waves are significantly reducing surface dissolved oxygen (DO) levels in lakes worldwide, according to a study published in Science Advances.

New Research Redraws Sahara’s Climate History Using a Vanishing Lake

New research reveals that only the most intense Atlantic-sourced storms are responsible for filling a normally dry lake in the northwestern Sahara, overturning previous assumptions about monsoonal influences. New research reveals that intense rainfall originating from the Atlantic Ocean is the main driver of modern lake-filling events in the northwestern Sahara. The study shows that [...]

Climate warming and heatwaves accelerate global lake deoxygenation, study reveals

Freshwater ecosystems require adequate oxygen levels to sustain aerobic life and maintain healthy biological communities. However, both long-term climate warming and the increasing frequency and intensity of short-term heatwaves are significantly reducing surface dissolved oxygen (DO) levels in lakes worldwide, according to a new study published in Science Advances.

According to a study, global warming could be much stronger in the long term than expected due to recouplings. The Paris goal of keeping the warming at well below two degrees Celsius is only achievable in "scenarios with very low emissions and lower climate sensitivity than currently assumed in the best estimate", warned the Potsdam Institute for Climate Impact Research (PIK) on Monday.
