Climate change has local consequences. It requires local action.

1. Calculate your family's carbon footprint. You can use carbon calculators freely available from the EPA or the Nature Conservancy.
2. Figure out which of your activities contribute most to global warming, and eliminate or reduce them. 
3. Consider projects that will cut your long-term carbon emissions, such as installing rooftop solar panels.
4. Call, write, or meet local politicians to encourage them to pursue policies aimed at mitigating greenhouse gas emissions and adapting to inevitable climate change. 

But it also demands national and global policy.

1. Support activist organizations like Citizens' Climate Lobby, which presses politicians to take action to reduce greenhouse gas emissions, or the Sunrise Movement, which advocates for radical economic and social change. 
2. Call, write, or meet state and federal politicians to demand action on climate change: from cutting fossil fuel subsidies to implementing a carbon tax. 
3. Join divestment campaigns to take away the money that powers fossil fuel development. 
4. Most importantly: get politically active and vote for candidates who recognize the threat posed by climate change!
