Nature Climate Change, Published online: 24 February 2020; doi:10.1038/s41558-020-0695-2 Exceptionally warm years in 2017–2019 have caused changes in the physical and biological characteristics of the Pacific Arctic Ocean. What these changes mean for the ecosystem and societal consequences will depend on if they are evidence of a transformation or anomalies in the system.
Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.
The European Research Council ERC has awarded an 11 million Euro Synergy grant called Deep Purple to Liane G. Benning at the GFZ German Research Centre for Geosciences in Potsdam, Germany, Alexandre Anesio at Aarhus University, Denmark, and Martyn Tranter at University of Bristol, UK. Their common goal is to examine over the next six years (starting in 2020) the role of glacier algae in progressively darkening the Greenland Ice Sheet surface in a warming climate.
It's not too late to rescue global marine life, according to a study outlining the steps needed for marine ecosystems to recover from damage by 2050. University of Queensland scientist Professor Catherine Lovelock said the study found many components of marine ecosystems could be rebuilt if we try harder to address the causes of their decline.
A study that included the first-ever winter sampling of phytoplankton in the North Atlantic revealed cells smaller than what scientists expected, meaning carbon sequestration models may be too optimistic.
Dr Celia Schunter from the School of Biological Sciences at The University of Hong Kong and a team of international scientists conducted a study to understand the molecular response of five species to the 2016 heatwave conditions that killed a third of the Great Barrier Reef corals. This is the world-first study tracking how wild fish populations respond to a severe marine heatwave. The results of the study were published in Science Advances.
