The 1972 Clean Water Act has driven significant improvements in U.S. water quality, according to the first comprehensive study of water pollution over the past several decades, by researchers at UC Berkeley and Iowa State University.

Light-absorbing brown carbon aerosols, emitted by wildfires, remain longer in the atmosphere than expected, which could have implications for climate predictions.

Stronger efforts to cut greenhouse gas emissions should be undertaken to avoid global warming of more than 1.5˚C - without relying on potentially more expensive or risky technologies to remove CO2 from the atmosphere or reduce the amount of sunlight reaching the Earth’s surface.

With the right public infrastructure investment, the United States could as much as double the amount of carbon dioxide emissions currently captured and stored worldwide within the next six years, according to an analysis by Princeton University researchers.

Novel UCSD study indicates global warming is costing U.S. economy about $250 billion per year.

In February 2018, Donald Trump signed into law new tax credits that reward oil companies for capturing carbon dioxide and preventing it from entering the atmosphere – either by burying the gas underground or by pumping it into wells to boost production. These tax credits, which have bipartisan support, are encouraging for those who believe that trapping CO2 from the fossil fuel industry – though no substitute for deploying cleaner energy sources – could help combat runaway climate change while society remains reliant on oil, gas and coal.

A new study has for the first time comprehensively accounted for permafrost carbon release when estimating emission budgets for climate targets.

Consumers need to stop demanding shark fin soup and other products in the absence of robust laws and sustainable practices regulating shark overfishing, research co-authored by the Sea Around Us initiative at UBC has found.

Researcher finds that California Coastal Act increases property values.

The “California and China: Leadership for a Low Carbon Future” conference at Berkeley highlighted collaboration on climate change.
