Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change -- and rapid change -- at the world's northern reaches, according to a new paper.
The former city and now archaeological site called Cantona in the highlands east of Mexico City appears to have been abandoned nearly 1,000 years ago as a result of a prolonged dry spell that lasted about 650 years, according to a new study by UC Berkeley geographers. The dry period, characterized by a long series of droughts, occurred during a nearly 2,000-year long period of increasing aridity throughout Mesoamerica that impacted other civilizations, including Teotihuacan.
The MODIS instrument that flies aboard two NASA satellites captured images of Tropical Cyclone Diamondra and Tropical Cyclone Eunice in the South Indian Ocean, and two separate images were combined to make one panorama of the two storms.
Though this image may look like they come from a science fiction movie, it is in fact a photograph of tropical cyclone Bansi as seen at night by astronauts on the International Space Station. The image was taken when the ISS was east of Madagascar.
In a commentary released in Nature Climate Change, a group of 13 scientists argue that the Nordic countries are in a unique position to showcase how to handle the growing pressure on the oceans. However, this relies on a collective ability to regard change as connected.
From the subarctic Pacific to the Chilean margins, extreme oxygen loss is stretching from the upper ocean to about 3,000 meters deep. In some oceanic regions, such loss occurred within 100 years or less, according to a UC Davis study.
A new study of marine organisms that make up the 'biofouling community' -- tiny creatures that attach themselves to ships' hulls and rocks in the ocean around the world -- shows how they adapt to changing ocean acidification. Reporting in the journal Global Change Biology, the authors examine how these communities may respond to future change.
Using satellite images to study changing patterns of surface water is a powerful tool for identifying conservationally important 'stepping stone' water bodies that could help aquatic species survive in a drying climate, a UNSW Australia-led study shows. The approach has been applied to the Swan Coastal Plain near Perth in Western Australia, which has more than 1,500 water bodies and is one of 25 designated biodiversity hotspots on the globe.
NASA and NOAA have provided night-time and daytime views of the Blizzard of 2015 from the Suomi NPP and the GOES-East satellites.
Scientists have reconstructed the past climate for the region around Cantona, a large fortified city in highland Mexico, and found the population drastically declined in the past, at least in part because of climate change.
