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.

Global warming will cause peatlands to absorb more carbon – but the effect will weaken as warming increases, new research suggests.

For the 30 per cent of Canadians who live within 500 metres of a major roadway, a new study reveals that the type of vehicles rolling past their homes can matter more than total traffic volume in determining the amount of air pollution they breathe.

An exploration to one of the deepest places on earth has captured rare footage of what is believed to be three new species of the elusive Snailfish.

Not all oil weighs equally on the scales of climate change.

Children carrying the ε4 variant of the APOE gene may be particularly vulnerable to the detrimental effects of air pollutants on the brain.

Groundwater containing excess nitrogen from agricultural fertilizers likely contaminated coral reefs on the Cook Islands according to a new study.

This year’s U.S. wildfire season has been extremely active: Twenty-five percent more acres have burned in 2018, beating the 10-year average.
