Lightning strikes in the Arctic tripled from 2010 to 2020, a finding University of Washington researchers attribute to rising temperatures due to human-caused climate change. The results, researchers say, suggest Arctic residents in northern Russia, Canada, Europe and Alaska need to prepare for the danger of more frequent lightning strikes. The study, published March 22 in […]
“I’m only here to once again remind you of the emergency we are in. The crisis that you and your predecessors have created and inflicted upon us.” In yet another fiery speech to attendees of an elite annual summit, climate activist Greta Thunberg made clear on Monday that young people aren’t backing down from demands that […]
New research reveals significant changes to the circulation of the North Pacific and its impact on the initial migration of humans from Asia to North America. The international study, led by the University of St. Andrews in Scotland and published Dec. 9 in Science Advances, provides a new picture of the circulation and climate of the […]
New research provides a glimpse into the future to help Arctic fishing communities prepare for change. The Pacific Arctic is undergoing a rapid transformation. As temperatures rise and sea ice melts, some species will do better than others. A new study suggests that pink salmon may be one of those species. “Our results suggest that warming […]
NOAA Fisheries scientists are part of an international team that set sail on April 11. They are studying the impacts of continued warm ocean temperatures in the Gulf of Alaska on Pacific salmon survival. It has been estimated that one-third of all Pacific salmon spend the winter in the Gulf of Alaska. While reduced in […]
A review article published in Nature Climate Change evaluates whether severe winter weather in the United States, Europe and Asia is sensitive to Arctic temperatures. The lead author is NSF-funded scientist Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research. Despite a warming planet, winter weather has remained surprisingly resilient across the mid-latitudes of the Northern […]
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 […]
