Unprecedented temperature extremes
Study of paleoclimate records indicates that high northern latitudes are experiencing unprecedented extreme temperatures not seen in the past 600 years.

Support for Ice Age CO2 changes
At the end of the last ice age, changes in ocean circulation patterns led to increased atmospheric CO2 levels. In this article, analysis of opal deposition supports the hypothesis that the release of CO2 was a result of the reduction of the glacial north atlantic intermediate water causing antarctic overturning, rather than the alternative hypothesis that westerly wind-induced effects were the driver of CO2 release.
Roots and fungi act as carbon sinks
Roots aren't just for absorbing water. This paper shows that roots and associated fungi in subarctic forests act as carbon sinks.
Boundary layer as lubricant to plate tectonics
Rigid oceanic plates slide around on a partially molten lube layer.
Terrestrial Accretion Under Oxidizing Conditions
Researchers find that terrestrial accretion may have occurred under more oxidizing conditions than previously thought.
Increasing nitrogen pollution in China
Nitrogen pollution from emissions and agricultural use in China are rivaling the levels seen in Europe in the 1980s.
Argon dating determines time scale of Cretaceous mass extinction
High-precision argon dating was used to analyze tektites and bentonites derived from a bolide impact associated with the mass extinction event at the boundary of the Cretaceous and Paleogene periods.
Influence of plate tectonics on subterranian evolution
This article describes how plate tectonics influenced the evolution of subterranean water crustaceans.
Coastal eutrophication driving salt marsh loss
Nutrient enrichment is shown to be a driver for salt marsh loss by decreasing below-ground plant mass and increasing rates of microbial decomposition.
Afternoon rain more likely over drier soils
Researchers examine the relationship between soil moisture and precipitation and find that rain fall preferentially over relatively dry soils.
