Autumn Warming No Longer Accelerating Carbon Loss in the North
An analysis of Point Barrow’s 40-year record points to the importance of calculating the carbon cycle’s response to temperature during the northern latitudes’ non-growing season.
Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes
Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.
Restored Wetlands Could Lower Local Surface Temperatures
A 3-year study of wetlands and cropland in a major California delta highlights the need to consider the physical effects of vegetation when planning land use changes.
Seasonal Leaf Production Is Key Control on Amazon Carbon Balance
Characterizing leaf phenology in process-based models reconciles both “dry season green-up” and drought controls on Amazonian carbon balance.
Evaluating the Accuracy of Seasonal Climate Predictions
An analysis of historical modeling outputs is improving our understanding of the relationships between different types of seasonal forecasting skills.
Fossilized Caribbean Corals Reveal Ancient Summer Rains
Isotope records and climate modeling suggest that the rainy Intertropical Convergence Zone expanded northward into the southern Caribbean during a warm interglacial period about 125,000 years ago.
How Ice Rafting Events Affect Asian Monsoon Hydroclimate
Cave stalagmites provide isotopic evidence that Bond events and Heinrich events have more variable effects on Asian monsoon hydroclimate during the last glacial period than during the Holocene.
Winter Conditions Are Changing Rapidly in Alpine Lake Ecosystems
LimnoAlp Workshop; Lake Cadagno, Switzerland, 10–15 September 2017
A Close-in Look at Saturn’s Periodic Space Bubble
When it comes to Saturn’s space environment, summer wins over winter in controlling the periodic flows of electrically charged particles and magnetic fields.
