Solving the climate crisis is not a technical problem, it is a political one. Politicians will take steps to restore the environment and protect human health if, and only if, citizens and voters demand it. The public generally favors clean air and water and limits on carbon pollution. But the fossil energy industry, powerful and wealthy, has mobilized its forces to block progress. That means citizens who want to move climate to the top of the political agenda will have to mobilize as well, by supporting, with determination, persistence and funding, organizations that are dedicated to averting climate chaos.
