What does the process reveal about the current status of the climate-modeling enterprise? That in the case of cloud feedback, it is difficult to come to “any firm conclusion” … even on the sign of the feedback… Read More
How Southern Ocean Echinoderm Larvae Respond to Elevated CO2 (25 Jun 2013)
According to the authors of this study, the “effects of elevated CO2 representative of near future climate scenarios are proportionally minor on [the] early development stages”… Read More
Recent Antarctic Sea Ice Extent in CMIP5 Models (25 Jun 2013)
In summing up their findings, Turner et al. conclude that “many of the Sea Ice Extent biases in the CMIP3 runs remain in CMIP5.” More particularly, for example, they state that “as with CMIP3, the models do not simulate the recent increase in Antarctic Sea Ice Extent observed in the satellite data”… Read More
Intraspecific Variability in the Response of Marine Microalgae to Environmental Change (25 Jun 2013)
Kremp et al. conclude that “depending on the strain of choice,” experiments using single isolates of the population they studied “could have given opposite response patterns,” which would likely have led to “contrasting predictions” about the future. And they indicate that this observation draws attention to the unavoidable fact that “responses observed in single strain experiments may not be representative” of the species or population in question, and that predictions for specific species behavior under future climatic conditions must thus “be treated with caution”… Read More
A Treeline Ecosystem in a CO2-Enriched World (26 Jun 2013)
Is there sufficient nitrogen in contemporary soils to sustain the enhanced growth typically provided by the aerial fertilization effect of rising atmospheric CO2 concentrations? In a word, yes!… Read More
Seven Millennia of Hurricane Activity along the Coast of Belize (26 Jun 2013)
What does the new record reveal about the effects of global warming on the destructive storms? It would appear to suggest that there are no hard-and-fast rules about how climate change may impact the development of future storms in these regions… Read More
Ruminant Fermentation of Maize Grown in CO2-Enriched Air (26 Jun 2013)
Is the process negatively impacted compared to that of maize grown in current ambient air? The authors of this study conclude that “changes in forage due to climate change will not result in significant alterations of rumen microbial community because of its pronounced ability of dynamic adaptation,” and, therefore, they suggest that “most parameters of rumen digestion will only be slightly influenced by plant material altered as a result of climatic changes”… Read More
