A comparison of water content in undeformed and deformed quartz indicates that grains may change shape via weakening processes that cannot be duplicated in laboratory experiments.Read More »Atmospheric Sciences
The presence of nitryl chloride in polluted urban air can enhance the production of ozone by up to 41%, according to a new modeling study constrained by ground-based measurements.Read More »Geology & Geophysics
An analysis of a seismic and gravity anomaly discovered in the middle mantle sheds new light on ancient oceans, the mantle's evolution, and ancient magmatism in the Arctic.Read More »Climate Change
To reduce the uncertainty associated with this important climate change index, recent studies have developed a new diurnal temperature range data set and compared the results to previous estimates.Read More »Atmospheric Sciences
Reducing emissions of short-lived gaseous sulfur pollutants from power plants had an immediate, local benefit, but controlling longer-lasting harmful particulate matter will require regional action.Read More »Climate Change
The temporary deceleration in warming across the Northern Hemisphere earlier this century could not have been foreseen by statistical forecasting methods, a new study concludes.Read More »
The results of a new study suggest that an improved understanding of the processes mobilizing mercury in soils will be necessary to predict water quality impacts.Read More »Ocean Sciences
An expanding zone of shallow, oxygen-depleted water in the eastern tropical Pacific Ocean may be vertically restricting the habitat of this important source of food, according to a recent study.Read More »Atmospheric Sciences
Enhanced technology and chemistry-climate models have advanced our understanding of the sources and processes controlling the evolution of the stratospheric aerosol layer, the so-called Junge layer.Read More »
