First, Advocate – become a committed advocate for solving the climate crisis.
Be ready to speak up any time the issue comes up.  Lovingly confront doubt that the crisis is real.  This is as important for addressing the climate crisis as confronting racist comments is to confronting racism.  Use social media to spread the word by posting links to events and videos and articles, and encourage your friends to repost them.

Second, Choose – deepen your commitment to make better consumer choices that reduce energy use and your impact on the environment.
Remember the four Rs – Reduce, Reuse, Recycle, Rot – and in that order.  If a whole bunch of us do a whole lot of little things it will add up to a real difference.  Beware of green-washing as you go about doing this.

Third, Join – join an organization that working on the issue.
There are several organizations that are organizing to address the climate crisis national and internationally.  One of my favorites if, which is organizing the Moving Planet day of action on September 24.  You might also check out The Alliance for Climate Protection, the Climate Reality Project, and Greenpeace.  Add your favorite organization in the comments section.

Four, Watchdog – contact news media when they put out claptrap on climate.
Let them know you’re fed up with their stubborn and cowardly resistance to reporting the facts of this issue.  Stay on them, stay on them, stay on them.

Five, Lobby – don’t give up on the political system.
Even though it’s rigged to support special interests, the more pressure citizens put on politicians and (especially) candidates, the more likely they are to pay attention and do something.  FDR is famous for telling a civil rights leader who was pressing him for change that he agreed about the need for greater equality.  Then FDR said, “Now go out and make me do it.”
