The United States must take decisive action to address the existential threat posed by fossil fuels and climate change. A growing global movement, represented by the Fossil Fuel Non-Proliferation Treaty initiative, calls for a bold and equitable plan to phase out fossil fuel production and accelerate the transition to renewable energy sources. This aligns with the need to limit global temperature rise to 1.5°C above pre-industrial levels, as underscored by the latest reports from the Intergovernmental Panel on Climate Change. Endorsing this treaty would demonstrate American leadership in confronting one of humanity's greatest challenges while charting a course toward a sustainable future for all.
