You are correct, climate change is the most important issue of our time.  But to combat that, first Democrats must figure out a way to win back the Congress, Senate and White House.  The 99% must unite through our common issues in order to beat the GOP's powerful machine of propaganda, campaign financing, voter suppression and gerrymandering.   Democratic voters must overwhelm the GOP in 2018, so that their efforts at de-funding social programs and education, distorting the truth and cheating the vote are not enough.  Once back in power the Democrats can attack climate change, the economic issues and other priorities.  Too bad letters to the R-G can only be 250 words, as many of us have a lot more to say!
