Upwelling hinders an efficient method to estimate a key measure of biological productivity in coastal waters, but accounting for surface temperatures could boost accuracy.Read More »Atmospheric Sciences
New research shows that there are more extremely hot days during the summer and more days that are considered extremely hot for the time of year, like abnormally warm days in the winter.Read More »Ocean Sciences
With refreezing in the western Arctic Ocean shifting later into the autumn, field research on changing air-ocean-ice interactions suggests that the Arctic is shifting to a more seasonal system.Read More »Climate Change
A new U.S. government report finds that climate change is already increasing risks to health, the economy, and ecosystems across the United States. These risks are expected to grow in the coming decades.Read More »
Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.Read More »Atmospheric Sciences
A 400,000-year calcium carbonate record from the ocean floor sheds light on deep-ocean circulation and on mechanisms driving climate patterns and atmospheric carbon dioxide concentrations.Read More »Hydrology, Cryosphere & Earth Surface
Ice cores and glacial records reveal that European glaciers retreated before the rise of industrialization in the 1870s, suggesting that soot deposition did not primarily drive the shift.Read More »Climate Change
