 B. B. Cael, an assistant professor in the Department of the Geophysical Sciences, talks about his work in ocean alkalinity and the importance of climate systems engineering research.

Two scientists argue that the growing commercial efforts to counter climate change by reflecting away sunlight will thwart responsible research in the field.

Our 2025 poll with The Associated Press–NORC Center for Public Affairs Research explored Americans' attitudes on climate change, their views on key climate and energy policies, how they feel about electric vehicles and the policies to encourage them, and their...

We should celebrate cleaner air, but we also have to reckon with an unintended consequence. It turns out that by reflecting sunlight back into space, tiny sulfur particles protected Earth from about a third of the warming caused by human...

When disaster strikes and funding fails, some experts and leaders are considering a Plan B: deliberately cooling the planet by reflecting sunlight back into space. This episode traces the science, the politics, and the ethics of geoengineering—from volcanic eruptions to...

David Keith, a pioneering climate scientist and founder of Carbon Engineering, unpacks the technological, policy, and economic hurdles to direct air capture and other approaches.

By: David Keith and Anthony Harding (Georgia Tech) Climate change has risks—and those risks are only increasing. Many of these might be reduced by solar geoengineering. Solar geoengineering also has risks, and it requires rigorous, transparent research before it is...
