How plate tectonics, mountains and deep-sea sediments have maintained Earth’s ‘Goldilocks’ climate

New modelling shows how tectonic plate movements, carbon-rich deep-sea sediment, and mountain weathering have regulated Earth’s climate.
These insects are basically little machines that convert carbon-rich leaves into nitrogen-rich poo. (John Gunn)

Very hungry caterpillars can have large effects on lake quality and carbon emissions

As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.

An effective climate change solution may lie in rocks beneath our feet

To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.

Deep sea carbon reservoirs once superheated the Earth – could it happen again?

Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
