Recent astronomical data has indicated that water worlds are likely to be abundant across the cosmos, which has raised questions about how the carbon cycle would function, for example, on a planet covered in 200km of water.
A recent piece in Scientific American tries to answer that question and points to Geophysical Sciences Professor Edwin Kite's work on the habitibility of exoplanet waterworlds. Kite shows that carbon dioxide can shift between ocean and atmosphere to maintain a habitable surface temperature that persists for more than 1 billion years.

Geophysical Sciences Professor Nicolas Dauphas's recent work calls into question the assumption that the majority of water found on earth arrived after the great impact that split the earth and moon into two bodies. Recent isotopic analyses done by Professor Dauphas and his team indicate that most of the water on earth was accreted before the giant impact.
