Oysters likely suffered toxic effects from the oil dispersant Corexit® 9500 when it was used to clean up the 2010 Deepwater Horizon oil spill, said Morris Animal Foundation-funded researchers at the University of Connecticut.

Committed to addressing the country’s severe air pollution, China is attempting a shift from coal to natural gas and is considering a variety of sources, including domestic and imported gas options as well as creating its own synthetic gas from coal.  

Nothing against the countryside, which is lovely, but cities are where things happen. They are magnets for trade, and they're where cultures meet. They're also where more than half the world’s population lives, a number that will only continue to grow.

While walking or driving along tree-lined streets in São Paulo, Brazil’s largest city, you will pass many a tipuana tree (Tipuana tipu). Also known as rosewood or tipu, it is a tall tree with a large spreading canopy and is ubiquitous in the city.

So far in 2018, wildfires have burned almost 7 million acres across the U.S. and their smoke has blanketed much of the West, with some smoke plumes extending all the way to the East Coast and beyond.

Global warming could lead to the extinction of up to 10% of frog and toad species endemic to Brazil’s Atlantic Rainforest biome within about the next 50 years. The temperature and precipitation regimes predicted to occur between 2050 and 2070 will be lethal for species that are less well adapted to climate variation and inhabit certain areas of the Atlantic Rainforest.

Tracking how air moves at night near the Earth's surface could provide insights into how air pollution spreads and when it's best to apply pesticides.

World, we have a problem.

A first of its kind study, led by Dr Claire Horwell of the Department of Earth Sciences and Institute of Hazard, Risk and Resilience, has found that industry-certified particle masks are most effective at protecting people from volcanic ash, whilst commonly used surgical masks offer less protection.

Black carbon refers to tiny carbon particles that form during incomplete combustion of carbon-based fuels. Black carbon particles absorb sunlight, so they are considered to contribute to global warming. However, the contribution of black carbon to the heating of the Earth's atmosphere is currently uncertain. Models that can accurately assess the warming effect of black carbon on our atmosphere are needed so that we can understand the contribution of these tiny carbon particles to climate change. The mixing state of black carbon particles and their particle size strongly influence their ability to absorb sunlight, but current models have large uncertainties associated with both particle size and mixing state.
