Published The cod population off the coast of Sweden is not extinct
(via sciencedaily.com) Original source Through DNA analyses, researchers have identified that there are still juvenile coastal cod off the west coast of Sweden. However, it is still difficult to find any mature adult cod in the area.
Published Past records help to predict different effects of future climate change on land and sea
(via sciencedaily.com) Original source Ongoing climate change driven by greenhouse gas emissions is often discussed in terms of global average warming. For example, the landmark Paris Agreement seeks to limit global warming to 1.5 degrees C, relative to pre-industrial levels. However, the extent of future warming will not be the same throughout the planet. One of the clearest regional differences in climate change is the faster warming over land than sea. This 'terrestrial amplification' of future warming has real-world implications for understanding and dealing with climate change.
Published Marine reserves unlikely to restore marine ecosystems
(via sciencedaily.com) Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.
Published Devastating cost of future coastal flooding for many developing nations predicted in new study
(via sciencedaily.com) New global modelling predicts the devastating socioeconomic impacts of future extreme coastal flooding for developing nations caused by climate change, with Asia, West Africa and Egypt facing severe costs in the coming decades.
Published Plastic debris in the Arctic comes from all around the world
(via sciencedaily.com) In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.
Published Changing climate conditions likely facilitated early human migration to the Americas at key intervals, research suggests
(via sciencedaily.com) Original source Researchers have pinpointed two intervals when ice and ocean conditions would have been favorable to support early human migration from Asia to North America late in the last ice age, a new paper shows.
Published More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice
(via sciencedaily.com) The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.
