Most Americans Say Climate Change Is Raising Their Bills
A new survey from the Yale Program on Climate Change Communication finds that two-thirds of registered voters think global warming is affecting the cost of living in the United States a view shared across the political spectrum. Energy is the cost Americans feel most acutely: a quarter of voters point to energy costs as the expense most impacted by global warming, more than food, transportation, or insurance. Looking specifically at utilities, 66% of registered voters think global warming is causing their home utility bills to rise. The findings suggest energy affordability could be a unifying entry point for climate conversations, offering a way to discuss climate change that resonates regardless of political affiliation

The Importance of Tracking Earth-System Methane Fluxes
Methane is one of the most powerful levers for slowing near‑term warming, yet the world still lacks the tools to track it with confidence. Sparkle Malone, assistant professor of ecosystem carbon capture, explains why a coordinated global observation system is essential for understanding both human and natural methane emissions.
