La Niña Subtype May Have a Big Impact on Aerosols in China
During a newly identified "flavor" of La Niña called La Niña Modoki, aerosol concentrations over different regions of eastern China may depend heavily on the strength of the event.
How Do Microbial Ecosystems and Climate Change Interact?
The American Society for Microbiology and the American Geophysical Union offer insights from a transdisciplinary collaboration of their scientists regarding this question and areas for further study.
As Winters Get Warmer, Sugar Maples May Absorb Less Silicon
Rising temperatures that reduce snow cover leave soils vulnerable to frost, reducing silicon uptake by trees, with potential effects on downstream ecosystems.
How Arctic Ice Affects Gas Exchange Between Air and Sea
Scientists begin to fill a major data gap by investigating carbon dioxide dynamics in a remote region of the Arctic Ocean.
Better Estimates of Clouds' Climate Effects Are on the Horizon
A recent update to an algorithm for processing satellite data could improve understanding of the variable climate effects of clouds composed of different amounts of ice and liquid.
Could Subsea Methane Hydrates Be a Warming “Tipping Point”?
The authors of a recent paper in Reviews of Geophysics answer questions about the potential for subsea methane hydrates to contribute to global warming.
Mushrooms Could Provide a Record of Grassland History
Scientists measured carbon isotopes in certain types of fungi to assess whether the organisms can track how climate change is affecting grasses.
High Arctic Emissions of a Strong Greenhouse Gas
Isotope data bring scientists one step closer to revealing the microbial processes behind nitrous oxide emission in the tundra.
Looking Up: Taking Photos May Improve Climate Models
Snapshots of clouds taken from the ground reveal orders of magnitude more detail than satellites.
