It may seem odd, but most people in last election voted for Democrats, who have climate change as part of their platform.
In 2012, the first congressional election after the last round of gerrymandering, Democratic House candidates won 50.59 percent of the vote — or 1.37 million more votes than Republican candidates — yet secured only 201 seats in Congress, compared to 234 seats for Republicans. The House of Representatives, the “people’s house,” no longer requires the most votes for power. source
So blaming "democracy" seems a little odd -- especially since we're a Republic.
