Examining data from satellites, a U.S. research team declares that “from this remarkable 30-year archive of satellite imagery, we thus see evidence of a greening trend,” which clearly indicates the net result of the climatic and physiological effects of atmospheric CO2 enrichment on Earth’s terrestrial plant life has in the mean been decidedly beneficial… Read More
Assessing the Performance of CMIP3 GCMs in Southeast Australia (11 Mar 2014)
Are they, as the saying goes, good enough for government work? Sadly, it appears older models outperform newer ones, which is not a step in the right direction… Read More
Modelling Aerosol-Cloud Interactions … Correctly (11 Mar 2014)
We’ve yet a long, long way to go before it can be done. According to the authors of this study, “fully resolved, global, multiyear simulations are not likely to become feasible for many decades.” And this analysis of the situation makes one wonder if the policy cart is being pushed way before the horse, when it comes to pushing for such drastic CO2 emission reductions that are continually promoted in order to prevent what may eventually be found to actually be no problem at all… Read More
Ocean Acidification and Hypoxia: Double Trouble for Tubeworms? (11 Mar 2014)
Two unpleasant circumstances challenge the lowly marine invertebrates. Are they doomed? Not according to the authors of this study, who conclude “the aragonite tube-forming tubeworm larvae have a high tolerance to hypoxia and may possess the capacity to acclimate over time, even in the phase of ocean acidification”… Read More
Floods of the European Alps (12 Mar 2014)
For the European Alps, there would appear to be good reason to believe that any further warming of the globe would not lead to flood-induced “increased threats to settlements, infrastructure, and human lives,” for real-world data suggest that it is cooling that leads to such consequences in that part of the world… Read More
North Atlantic Copepods Exposed to Very Acidified Seawater (12 Mar 2014)
Writing in the concluding paragraph of their paper, the authors state “the absence of any apparent reduction in the overall survival during the present medium-term exposure to 3300 ppm CO2, indicates that survival of Calanus eggs and nauplii may be robust against the direct effects of the worst-case CO2 scenario predicted for year 2300″… Read More
Modeling European Temperatures: CMIP5 Biases and Uncertainty (12 Mar 2014)
In light of the fact that the parameters evaluated in this study were rather basic – almost mundane, in fact – it is surprising to find that the latest and greatest in GCMs did not come through with flying colors… Read More
