COP28

With a record number of oil, gas and coal representatives at this year's COP28 climate talks, climate scientists worry industry influence could water down language on fossil fuels.

Advocates say human-driven climate change is hurting people's health worldwide–but taking action like reducing reliance on fossil fuels lowers risks immediately.

The United States looms large at the COP28 climate summit in Dubai. Historically, it's responsible for more greenhouse gas emissions than any other nation. But it's also key for major breakthroughs.

Climate science shows that beyond 1.5 degrees Celsius of warming, impacts in the U.S. get substantially worse. The world is on track for almost double that level of warming by the end of the century.
