You have to vote for the Greenest candidate in your party. If there isn't one run yourself. Be hardcore and hardline the planet is burning.

Convince everyone to be a single issue Climate Voter. Make it the ONLY issue that anyone can win an election on. Take over the existing parties with Climate Hawks and change will start happening.

While that's happening organize, organize, organize. Because you cannot win if you don't have a majority.

That's the problem right now. The majority will not vote for what it's going to take.
