Join Nancy: Demand Action to Combat Climate Change Trump and his Administration have failed to address the threat of climate change to our environment, our nation, and our future. Ignoring a problem won’t make it go away. We’ve been warned by scientists in the United States and around the globe that if we don’t do something soon, the damage of climate change could be irreversible. It’s time for Trump and Republicans to work with Democrats to address climate change. Sign on and show your support for action.
