The single most important thing we can do to protect our communities from climate change is to reduce dangerous carbon pollution.

When climate change supercharges weather patterns, the disadvantaged often suffer first and most.

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.

Climate change is the central environmental ill of our time. We have an obligation to protect our children from the dangers of this widening scourge, and we aren't yet doing enough about it.

The Keystone XL pipeline is a threat to our nation. It would increase pollution and intensify climate change for generations to come. We must raise our voices and demand our leaders reject this dirty scheme.

Carbon pollution contributes to climate change, which causes temperatures to rise. Hotter temperatures mean more smog in the air, and breathing smog can inflame deep lung tissue. Repeated inflammation over time can permanently scar lung tissue, even in low concentrations.
