Scientists know that the climate is changing because of human activity– the greatest uncertainty is about the future level of emissions. If we act on climate now, we can make a better future.
The climate is already changing and more changes are coming.
Addressing climate change requires mitigation— to reduce greenhouse gas emissions that cause climate change– and adaptation— to help communities everywhere cope with the changes that are happening.
We can all make a difference–
at home, at work, in our communities.
