Managed burning on moorland in the UK led to millions of people being exposed to unsafe levels of fine particulate pollution, according to research led by Ailish Graham and the Royal Society for the Protection of Birds (RSPB). Prescribed burning is traditionally used to manage heather for grouse shooting across the UK uplands. Until recently...
The APARC assessment report on the impact of the huge 2022 Hunga eruption has just been published. The Hunga volcano in the tropical Pacific erupted in January 2022, sending a plume of vaporised seawater deep into the stratosphere in an explosion that equalled the size of Krakatoa’s in 1883. The Hunga assessment report’s main findings...
We have co-authored a new Nature review paper on short-lived halogens. More information soon. See https://www.nature.com/articles/s41586-025-09753-x
Humankind will soon lose a great deal of vigilance over the ozone layer, which shields life on Earth from harmful solar radiation. The impending loss of NASA’s Aura and the Canadian Space Agency’s SCISAT satellites threatens scientists’ ability to closely monitor compounds that destroy ozone and alter stratospheric circulation. With no planned missions to replace...
Group members, led by Chris Wilson, joined a UN-led collaboration to measure methane emissions from the 2022 Nord Stream Pipeline Leak – the largest ever leak of methane recorded. We employed the atmospheric chemistry transport model, TOMCAT, to track the methane plume over 1,500 km back to its source and produce an estimate of the...
The Mayor of West Yorkshire, Tracy Brabin, fulfilled an ambition by meeting PhD student Emily Dowd at the university. Mayor Brabin was on campus to attend the launch of the UK Earth Observation Network for Sustainability (UK-EONS) and was delighted to secure an unexpected photo with Emily. In her speech the Mayor paid tribute to...
PhD student Emily Dowd achieved the most-viewed BBC Science article on the BBC Website on 16/9/2023: Major UK methane greenhouse gas leak spotted from space. The story relates to Emily's use of GHGSat satellite data to discover a natural gas leak from a pipeline near Cheltenham. This received widespread media attention and is now published...
Rising nitrous oxide emissions are jeopardizing climate goals and the Paris Accord, according to a new international study, which included results from TOMCAT (INVICAT) inversions. The growing use of nitrogen fertilizers in the production of food worldwide is increasing concentrations of nitrous oxide in the atmosphere—a greenhouse gas 300 times more potent than carbon dioxide—which...
