Climate change is real. The United States should take its rightful place as the leader of the free world and set an example in the area of carbon emissions. If the world acts together, we can find solutions to this difficult problem. But, we cannot solve a problem as long as our leaders continue to deny that the problem exists, or to maintain that there is no solution to the problem so let’s ignore it - pretend it doesn’t exist - and hope it goes away. We solved the problem of landing on the moon. If we put our minds and resources together we can solve the challenges of climate change.
