Earth's magnetic field broke down 42,000 years ago and caused massive sudden climate change

The world experienced a few centuries of apocalyptic conditions 42,000 years ago, triggered by a reversal of the Earth's magnetic poles combined with changes in the Sun's behavior. That's the key finding of our new multidisciplinary ...

Restoring peat bogs could slow climate change – and revive a forgotten world

Bogs, mires, fens and marshes—just their names seem to conjure myth and mystery. Though today, our interest in these waterlogged landscapes tends to be more prosaic. Because of a lack of oxygen, they can build up vast quantities ...
