Arctic report card: Permafrost thawing at a faster pace
Permafrost in the Arctic is thawing at a faster clip, according to a new report released Tuesday. Water is also warming and sea ice is melting at the fastest pace in 1,500 years at the top of the world. The annual report released Tuesday by the National Oceanic and Atmospheric Administration showed slightly less warming in many measurements than a record hot 2016. But scientists remain concerned because the far northern region is warming twice as fast as the rest of the globe and has reached a level of warming that’s unprecedented in modern times.
The Arctic is warming faster than it has in 1,500 years
The Arctic is running a fever. The magnitude and pace of the recent Arctic sea-ice decline and ocean warming is "unprecedented" in at least the past 1,500 years and likely much longer, according to a federal report released Tuesday by the National Oceanic and Atmospheric
Scientists Need Your Help Rescuing 100-Year-Old Weather Records
A new citizen-science project needs volunteers to digitize decades of temperature, rain and barometric data from across western Europe
Submarine volcanoes add to ocean soundscape
Most volcanoes erupt beneath the ocean, but scientists know little about them compared to what they know about volcanoes that eject their lava on dry land. Gabrielle Tepp of the Alaska Volcano Observatory and the U.S. Geological Survey thinks that with improved monitoring, scientists can learn more about these submarine eruptions, which threaten travel and alter the ocean soundscape.
Melting Ice Could Mess Up Deep Sea Chemistry
Melting glaciers might be making ocean water more acidic, an unexpected finding that's given scientists new cause for concern. A new study published yesterday in the journal Nature Climate Change suggests surprising ways that climate change is drastically altering the water chemistry in deep seas—a process that may happen faster than researchers anticipated.
