Reason for despair: Climate change is the biggest challenge our planet faces. The science is clear, the risks are real, and the phenomenon’s impact on every part of our planet is increasingly visible. In mid-December, nearly 200 countries met in Paris to secure a historic agreement to reduce the impacts of the global threat. The negotiators for every single country involved have accepted that we need to take immediate and substantive action on this threat. Back at home, however, Congressional Republicans continued their decades of denial. In a symbolic rebuff of global urgency on the issue, both the House and Senate voted to repeal President Obama’s Clean Power Plan. By the time our legislators—a few hundred people—finally accept the overwhelming scientific evidence about the threat, I despair that time will have run out for future generations. I fear that killing, or endlessly delaying, the nation’s serious efforts to mitigate this threat will be catastrophic: rising seas swallowing island nations, floods wiping out towns and villages, unprecedented heat waves and drought destroying crops and lives, and even global instability that provokes wars.
Reason for hope: What gives me optimism is watching our country take a positive role in the Paris international-climate agreements after decades of foot dragging on the issue. When the United States leads, other countries follow. This means that the U.S. efforts to secure strong climate actions in Paris and at home will make a hugely positive impact globally on carbon emissions. The United States has, in fact, long been a leader on environmental technology innovation. In the 1970s, it was American car-emission standards that led to the development of catalytic convertors. These devices were the first to ever clean up the toxic soup coming out of cars’ tailpipes.
