Atmospheric scientists are embarking on two new research projects supported by the U.S. National Science Foundation that involve using sophisticated planes to understand the atmospheric chemistry and ...
The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate, according to a comprehensive new study of Arctic conditions.Weather patterns in ...
Melting of Arctic ice caused by climate change has exposed more sea surface to the atmosphere. Scientists have long suspected this trend would increase carbon dioxide in Arctic Ocean waters.Now U...
In October 2019, scientists froze a ship filled with equipment into Arctic sea ice with the intention of drifting across the Arctic Ocean for a full year, gathering data on polar atmosphere, ice and o...
A new 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...
The extent of polar sea ice is one of the key parameters of cryosphere and polar environmental change, which plays an important role in the study of global climate change. In this paper, the monthly p...
Arctic sea ice in recent decades has declined even faster than predicted by most models of climate change. Many scientists have suspected that the trend now underway is a combination of global warming...
The global climate is a complex machine in which some pieces are separate yet others are connected. Scientists try to discover the connections to predict what will happen to our climate, especially in...
Vanishing Arctic sea ice. Dogged weather systems over Greenland. Far-flung surface ice melting on the massive island.These dramatic trends and global sea-level rise are linked, according to a study co...
The National Science Foundation (NSF) has made a five-year, $5.9 million award to a national partnership, led by the National Center for Ecological Analysis and Synthesis (NCEAS) at the University of ...
For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surfa...
A new study of sharks that lived in warm Arctic waters millions of years ago suggests that some shark species could handle the falling Arctic salinity that may come with rising temperatures.
Chlorine dioxide, OClO, column amounts retrieved from measurements of the SCIAMACHY satellite instrument are presented and validated by comparison with simultaneous ground-based DOAS observations. In ...
On average, airborne aerosol particles cool the Earth's surface directly by absorbing and scattering sunlight and indirectly by influencing cloud reflectivity, life time, thickness or extent. Here we ...
Absorption of radiation by ice is extremely weak at visible and near-ultraviolet wavelengths, so small amounts of light-absorbing impurities in snow can dominate the absorption of solar radiation at t...
