Satellite data can now routinely be used to detect low levels of sulfur dioxide emissions from volcanoes, giving scientists another tool to provide early warnings of volcanic unrest. The new approach is the result of work led by research assistant professor Taryn Lopez of the University of Alaska Fairbanks Geophysical Institute. Lopez is also a […]
New research shines light on poorly understood processes Geoscientist Michael Rawlins of the University of Massachusetts Amherst is improving the understanding of the Arctic’s carbon cycle — the way carbon is transferred among the land, ocean and atmosphere. To better understand future trends in atmospheric carbon dioxide and climate change, a fuller picture of how carbon cycles […]
The U.S space agency NASA says its Perseverance rover has converted carbon dioxide (CO2) in the Martian atmosphere to oxygen, a critical step toward future human exploration of Mars. NASA on Monday said a toaster-size, experimental instrument on the rover called the Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE), produced about 5.4 grams of […]
Video: Guðfinna Aðalgeirsdóttir, also known as Tolly, a glaciologist and university professor from Iceland, recommends people watch Swedish high-school student Greta Thunberg’s presentation. Youtube Icelanders will soon install a plaque they hope people will read, long after those who bolted it to a mountain are dead. Near a withering glacier, the sign reads: […]
