The emissions and methane leaks from new gas plants zero out the CO2 cuts achieved from closing coal plants, a peer-reviewed analysis found.

Long-lived greenhouse gas could hinder international climate goals, researchers say

How in-person does science have to be?

Coal plant upgrades led to a dramatic reduction in sulfur dioxide emissions. But those particles also help reflect solar heat away from the planet.

Susan Trumbore, UCI professor of Earth system science, is among four recipients of the 2020 Balzan Prize, one of the most prestigious international awards in natural science and humanities.

California’s unprecedented wildfires, driven by man-made climate change, are pumping the atmosphere with tens of millions of tons of carbon dioxide that will only drive global temperatures higher. 

Pine Island and Thwaites glaciers already contribute 5 percent of sea-level rise.

UCI scientists quantify impact with NASA satellite data and simulations

From measuring atmospheric circulation, to using living cells to create artificial materials, our new faculty cover a broad spectrum.

There is global interest in the potential for a hydrogen economy, in part driven by a concern over climate change and the need to move away from fossil fuels.
