Rift between developed and developing nations might be too great.

The chances of a strong treaty emerging from the United Nations climate talks in Copenhagen seem small, but recent progress offers hope. (Editorial)

Mass loss from the glaciers along the margins of the Greenland and Antarctic ice sheets is increasingly contributing to sea level rise.

About 34 million years ago, the first major Antarctic ice sheets appeared, suggesting that major cooling had taken place; however, the global transition into this icehouse climate remains poorly constrained.

Phosphate-based fertilizers have helped spur agricultural gains in the past century, but the world may soon run out of them. Natasha Gilbert investigates the potential phosphate crisis.

Patterns of sea-surface warming and cooling in the tropical Pacific seem to be changing, as do the associated atmospheric effects. Increased global warming is implicated in these shifts in El Ni

When American and Chinese scientists agreed to measure pollution and dust over China, nobody foresaw how difficult it would be.
