Climate Change Impacts on Wheat Production in Central Asia (3 Dec 2013)
A team of 20 researchers reports that “the overall simulated impact of climate change on wheat productivity in Central Asia is positive,” noting that “a warmer climate explains most of this positive impact” and that “CO2 fertilization adds to it”… Read More
The Strange “Global Warming” of the Antarctic Peninsula (3 Dec 2013)
There hasn’t been a heat wave there since the start of temperature measurements… Read More
The Indian Ocean Dipole in CMIP5 Models (3 Dec 2013)
How accurately is it portrayed? Much less than desired, as the results of this study “suggest that caution should be exercised in interpreting climate projections in the Indian Ocean Dipole-affected regions”… Read More
Long-Term Effects of Atmospheric CO2 Enrichment on Plant-Insect Interactions (3 Dec 2013)
Elevated CO2 reduced the number of leaves damaged by leaf miners, leaf tiers, leaf chewers, eyespot galls and other leaf galls for all three oak species as well as the one legume examined in both of the years of this study… Read More
Modeling the South American Monsoon System (4 Dec 2013)
How well has it been done to date? Apparently not well enough to know the future, as the authors conclude that “how precipitation during the South American Monsoon System will change in the coming decades is still an open question”… Read More
Simulating the MJO and Convectively Coupled Equatorial Waves (4 Dec 2013)
The authors of this work evaluate “the simulation of the Madden-Julian oscillation (MJO) and convectively coupled equatorial waves (CCEWs) in 20 models from the Coupled Model Intercomparison Project (CMIP) phase 5 (CMIP5) in the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) and compares the results with the simulation of CMIP phase 3 (CMIP3) models in the IPCC Fourth Assessment Report (AR4).” Has their been any improvement over this time?… Read More
Effects of Atmospheric CO2 and Light Intensity on Spinach (4 Dec 2013)
Not only did elevated CO2 increase both the fresh and dry weight of spinich, it improved the food quality, enhancing the organoleptic quality (i.e., its taste, color, odor or feel)… Read More
Arctic Clouds and Sea Ice in CMIP5 Climate Models (10 Dec 2013)
How well are they represented? Based on the research findings of this study, not very. And commenting on the ramifications of such inadequacy, the authors state: “the fact that present-day sea-ice albedo is so badly constrained in GCMs [global climate models] impacts the fidelity of future scenario assessments of the Arctic region and should therefore be a concern for the modeling community”… Read More
Creating Global Climate Models for Agricultural Impact Research (10 Dec 2013)
The authors of this study state that “future outlooks of agricultural production and food security are contingent on the skill of GCMs [global climate models] in reproducing seasonal rainfall and temperatures.” An assessment of that “skill,” however left much to be desired, with the authors concluding that it could well be decades before they are useful… Read More
Solar and Planetary Influences on Global Climate Change (10 Dec 2013)
They may be very significant, as the authors of this report concludes that “about 50-60% of the warming observed since 1850 and since 1970 was induced by natural oscillations likely resulting from harmonic astronomical forcings that are not yet included in the GCMs”… Read More
Respiration of Cold-Water Corals in CO2-Enriched Seawater (10 Dec 2013)
No significant change in respiration was found as a function of increasing pCO2, which finding held true across the full range of pCO2 studied (up to a high of 1215 µatm). As discussed in this review, such a finding is very good news for cold-water corals… Read More
Cold-Water Corals Feeling Laboratory Heat … and Loving It! (11 Dec 2013)
Conventional wisdom fails again, as the results of this study suggest that two cold-water corals (CWC) “may be capable of surviving in warmer environments than previously reported, and thus challenge temperature as the paramount limiting environmental factor for the occurrence of some CWC species”… Read More
Projecting Global Changes in Precipitation Extremes (11 Dec 2013)
With all of the trouble researchers seem to find with the ability of the world’s most cutting-edge climate models to “predict the past,” so to speak, it makes little sense to put much value in what they are predicting for the future… Read More
Earth’s Changing Biosphere (11 Dec 2013)
Another scientist comments on a very important paper, writing that “the biosphere is changing, and changing rapidly”… Read More
