Mangroves, salt marshes and sea grass lock away carbon at up to five times the rate of tropical forests.

Healthy forests and wetlands stand sentry against the dangers of climate change, absorbing carbon dioxide from the atmosphere and locking it away in plants, root systems and soil.

Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.

Countries have made impressive pledges to cut carbon pollution, but we have to ensure these promises become actions.

Putting a tax on carbon could be an effective approach for curbing global warming pollution.

Shell Oil's decision to pull the plug on drilling for oil in the Chukchi Sea is a major victory for the Arctic.
