Dead-Zone Nutrient Reduction Target Pushed Out to 2035

Progress has been achieved in certain watersheds, but pushing back the target date to reduce run-off of nitrogen and phosphorous two decades is a testament to the extent and intractability of the problem.

New Research Reveals Climate Warming 55 MYA was Geologically Instantaneous

New research into past changes in climate indicates that global warming can take place much more suddenly than previously thought – over the course of only about 13 years. Temperatures at high latitudes rose as much as 8ºC (14ºF) and oceans warmed from surface to bottom some 55 million years ago during what’s known as the Paleocene-Eocene Thermal Maximum (PETM)….

Analogues from Earth’s Past Bode Ill for Coral Reefs, Marine Ecosystems

In a bid to anticipate the effects of a warming world, climate scientists around the world are scouring the geological record for modern-day analogues – periods of Earth history when the concentration of carbon dioxide (CO2) in the atmosphere reached or exceeded the 400 parts per million (ppm) we find today. Delving into climate, marine biology, ecosystems and the marine…

Washington State Pushed to Recognize Threat of Ocean Acidification to Coastal Waters

Ocean acidification is receiving greater attention from marine scientists as ocean waters worldwide have been found to be getting more acidic. Absorbing and storing carbon dioxide from the atmosphere, the world ocean – including the plankton, coral and shellfish that live in it – is the largest carbon sink on the planet, but its capacity is limited. Atmospheric carbon dioxide…

Warming Climate Brings Sea Level Rise, Land Loss and Marine Migrations to Europe’s Seas

Europe’s seas are changing at an unprecedented rate, much faster than climate scientists anticipated.
Seawater temperatures have been rising around 10-times faster than average over the past 25 years, while wind speeds have also been increasing. The combination of rising sea levels and stronger winds has resulted in the loss of 15% of Europe’s coasts, according to recently completed EU-sponsored marine research.
