A long-feared scenario in which global warming causes Arctic permafrost to melt and release enough methane—a potent greenhouse gas–to accelerate warming and cause catastrophe probably won’t happen. That is the conclusion of a study appearing in the journal Science that began more than 20 years ago as a query posed by Jeff Severinghaus, a geoscientist at the Scripps Institution […]
The Arctic has experienced the warming effects of global climate change faster than any other region on the planet. Scientists at the Scripps Institution of Oceanography have developed a new theory aided by computer simulations and observations that helps explain why this occurs. A team led by Scripps researcher Emma Beer observed the changes taking place […]
Rapid changes in the environment brought on by warming temperatures and increasing ocean acidification are prompting new direction in research, say scientists who addressed the 2020 Alaska Marine Science Symposium in Anchorage, Alaska. “Everything is new,” said Cisco Werner, chief science advisor to NOAA Fisheries, in his presentation to dozens of participants gathered to […]
The common murre is a self-sufficient, resilient bird. Though the seabird must eat about half of its body weight in prey each day, common murres are experts at catching the small “forage fish” they need to survive. Herring, sardines, anchovies and even juvenile salmon are no match for a hungry murre. So when nearly […]
