A University of Queensland-led international study could lead to more accurate predictions or the rate of global warming from greenhouse gas emissions produced by thawing permafrost in the next 100 years. The study of the microorganisms involved in permafrost carbon degradation links changing microbial communities and biogeochemistry to the rise of greenhouse gas emissions. It […]
Scientists involved in the Alaska ShoreZone program have been steadily imaging and mapping Alaska’s rich coastal habitats since 2001. Over ninety percent of Alaska’s approximately 80,000 km of coastline has been completed, but gaps remain. During NOAA Fisheries’ Habitat Month in July 2018, imaging experts are filling in one of those gaps – Glacier Bay […]
New observations by three of the world’s largest radio telescopes have revealed that an asteroid discovered last year is actually two objects, each about 3,000 feet (900 meters) in size, orbiting each other. Near-Earth asteroid 2017 YE5 was discovered with observations provided by the Morocco Oukaimeden Sky Survey on Dec. 21, 2017, but no details […]
When the Chicxulub asteroid smashed into Earth 65 million years ago, the event drove an abrupt and long-lasting era of global warming, a new study reports. The results , published in the May 25 issue of Science, suggest that the asteroid impact caused a rapid temperature increase of 5 degrees Celsius (roughly 9 degrees Fahrenheit) that endured for […]
