At a shallow-water cold-vent system releasing CO2 directly into the ocean off the island of Vulcano, NE Sicily, the stimulation of biomass in benthic assemblages was found to increase fivefold along a natural gradient of CO2 ranging from 419 to 1611 ppm... Read More

Fine-Tuning the Spatial Distributions of Species’ Thermal Habitats (26 Nov 2013)
It makes a world of difference when assessing their ability to avoid warming-induced extinction, as the authors of this study conclude that “thermal variability within 1-km2 units strongly increases local spatial buffering of future climate warming across Northern Europe, even in the flattest terrains,” providing yet another example that this variability in temperature “provides buffering to mitigate climate-change impacts”...

Cloud Tuning in a Malleable Climate Model (26 Nov 2013)
The results of this analysis indicate that “the simulated temperature trend best matches [the] observed trend when the model adopts the threshold [cloud particle] radius that worst reproduces satellite-observed microphysical statistics and vice versa,” which represents a stunning admission of an equally stunning model failure...

The Amundsen-Bellingshausen Seas Low in CMIP5 Climate Models (26 Nov 2013)
This atmospheric phenomenon strongly influences the climate of West Antarctica, yet the results of this study show that “the majority of CMIP5 models ... have a correspondingly poor representation of West Antarctic climate due to difficulties in representing the Amundsen-Bellingshausen Seas Low annual cycle, particularly its longitudinal position”...

Elevated CO2 Reduces Ceratocystis Wilt in Two Eucalyptus Clones (27 Nov 2013)
Results from this study show that “an increased CO2 concentration can reduce the severity of Ceratocystis wilt and stimulate the growth of Eucalyptus clonal plantlets.” And it does it all at one and the same time... Read More

Modeling the West African Monsoon (27 Nov 2013)
A study conducted in an effort to determine the degree to which several models of the Coupled Model Intercomparison Project (CMIP) phase 5 (CMIP5) are able to reconstruct the past behavior of the West African Monsoonthe reveals the CMIP5 models “demand further work to achieve a reasonable realism”...

The Impacts of Business-As-Usual Projected Altered Temperature, Salinity and pCO2 on Filamentous Cyanobacteria of the Baltic Sea (27 Nov 2013)
The pair of researchers who conducted this analysis conclude that “the projected A1FI scenario [of future climate change] might be beneficial for the two species dominating the extensive summer blooms in the Baltic Proper”... Read More
