When nature harms itself: Five scary climate feedback loops

DW, 4/5/18

The thing about climate change is, the worse it gets – the worse it gets. Feedback loops accelerate the warming process. Now, scientists looking at lakes have found yet another alarming vicious circle to add to the list.

Lakes make a tiny fraction of the world’s water, but they’re home to lots of plants and animals. They’re often situated in the midst of still more biodiversity, in the form of forest. At least, they used to be.

Lately, forests have been vanishing, while aquatic plants continue to thrive. Due to this change, the lakes of the northern hemisphere could almost double their methane emissions over the next 50 years, new research has shown. Why? Climate change.

This increase of emissions will further contribute to global warming, in what scientists call a positive climate feedback loop.

And it’s just the latest addition to a growing list of ways we’re altering natural processes with spiraling impacts on the climate and carbon cycle….
