Researchers found that when water temperatures heat up for corals, fish ‘tempers’ cool down, providing the first clear evidence of coral bleaching serving as a trigger for rapid change in reef fish behaviour. 

Air pollution in the U.S. has decreased since about 1990, and a new study conducted at the University of North Carolina at Chapel Hill now shows that this air quality improvement has brought substantial public health benefits. The study, published Oct 19 in the journal Atmospheric Chemistry and Physics, found that deaths related to air pollution were nearly halved between 1990 and 2010.

The Intergovernmental Panel on Climate Change (IPCC) has published its Special Report on Global Warming of 1.5°C, a new assessment on minimizing global warming, and multiple IIASA researchers were involved in its production.

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.
