The real climate risks to Ireland from changes to the Atlantic currents that sustain our mild climate are obscured by exaggerated claims in media headlines and movies.

That’s according to Dr Gerard McCarthy, a Maynooth University (MU) oceanographer at the Irish Climate Analysis and Research UnitS (ICARUS) in the Department of Geography, who has led a new article for Nature Climate Change.

The latest paper is a retrospective on a landmark 2015 study led by Professor Stefan Rahmstorf, which identified long-term Atlantic cooling as a sign that the Atlantic Meridional Circulation (AMOC) was weakening.

In a paper published in SCIENCE CHINA Earth Sciences, a research team systematically interpreted the key scientific issues such as the DO threshold, structural characteristics, distribution patterns, formation and maintenance mechanisms, and driving factors of the OMZ in the context of global change. It may provide important scientific basis for further exploring the coupling relationship between global change and oceanic OMZ, and for understanding marine hypoxia and deoxygenation issues from a global perspective

A remarkable new discovery is shedding light on one of the greatest survival stories in Earth’s history, and answering a decades-old scientific mystery. Lystrosaurus, a hardy, plant-eating mammal ancestor, rose to prominence in the wake of the End-Permian Mass Extinction some 252 million years ago, the most devastating extinction event our planet has ever experienced. While countless species vanished, Lystrosaurus not only survived, but thrived in a world marked by extreme environmental instability, intense heat, and prolonged droughts.
