Leaving the Paris Climate Accord diminished America. We have relinquished our leadership role in combating the most serious environmental, economic and social problem confronting planet Earth. Human-caused increases in CO2 and methane are well documented, and if not controlled have the potential to disrupt global food production, displace millions who live in coastal population centers, and produce unprecedented human population movements.
Climate change threatens future generations of humans and all the other species that we depend on. The United States of America cannot exist isolated from the rest of the world community. "America First" is an obsolete agenda that is incompatible in the interconnected world of today.
