All the forests in the world pale in comparison to the ocean when it comes to absorbing carbon dioxide from the atmosphere. The ocean is the world's largest natural carbon sink, absorbing about a quarter of all CO2 emissions every year (and most of the excess heat trapped in Eart

The use of fossil fuels alters both the concentration and the carbon isotope composition of carbon dioxide in the atmosphere. Since surface water exchanges carbon dioxide with the atmosphere, this also alters the isotopic composition of the carbon dissolved in the ocean. In a new

Spreading finely crushed basalt across farmland has been promoted as a relatively simple way to remove large quantities of carbon dioxide from the atmosphere. But a new study led by Cornell researchers suggests the real-world potential of this method, known as enhanced weathering
