The thawing and erosion of Arctic permafrost coasts has dramatically increased in the past years and the sea is now consuming more than 20 metres of land per year at some locations. The earth masses removed in this process increasingly...
Eelgrass, a marine plant crucial to the success of migrating juvenile salmon and spawning Pacific herring, is stable and flourishing in Puget Sound, despite a doubling of the region's human population and significant shoreline development over the past several...
One of the world's largest ocean circulation systems may not be as stable as today's weather models predict, according to a new study. In fact, changes in the Atlantic Meridional Overturning Circulation (AMOC) the same deep-water ocean current featured in...
It has long been suspected that humans and the urban areas we create are having an important and surprisingly current and ongoing effect on evolution, which may have significant implications for the sustainability of global ecosystems. A new multi-institution study...
