Antarctic Sea Ice Extent: How Has It Changed Since 1979? (31 October 2015)
One would think that one could correctly guess at least the sign (increase or decrease) of the change, especially if one was a scientist, and even more especially if one was a climate scientist, and even doubly more especially if one was a climate modelling scientist. However ...

Near-Surface Atmospheric Variables in CMIP5 Models (26 October 2015)
One might think that these basic "down to earth" properties of low-level weather phenomena would be rather easy to model; but if one did, he would be thinking something that even today's best-performing climate models are unable to do to the degree of correctness required to accurately inform us of the potential effects of historical and still-ongoing atmospheric CO2 enrichment...

Interactive Effects of Elevated CO2 and Air Pollution on Wheat -- Summary (21 October 2015)
Atmospheric CO2 enrichment typically enhances photosynthesis and biomass production in wheat (Triticum aestivum) under normal growing conditions. But what happens when environmental conditions are less than ideal? This Summary investigates this question as it pertains to the impact of air pollutants on the growth and development of wheat, as learned from a number of scientific studies published on this topic...

What Drives Coral Calcification on Heron Reef? (21 October 2015)

Ocean Acidification and Warming (Effects on Corals: Field Studies) -- Summary (14 October 2015)
Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Fewer studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several of such studies for coral reefs, as reported in various field-based studies on the topic. Contrary to what is widely assumed and reported, the studies reviewed here collectively reveal that many corals will remain unaffected by rising temperatures and atmospheric CO2 concentrations. Furthermore, in contrast to projections, some will likely experience growth and performance benefits...

Deserts (Expanding or Shrinking?) -- Summary (7 October 2015)
Back when the atmosphere's CO2 concentration was approximately 340 ppm (up from a pre-industrial value on the order of 280 ppm), Idso (1982) stated in a small self-published book (Carbon Dioxide: Friend or Foe?) that if the air's CO2 content continued to climb, it would ultimately enhance plant growth and water use efficiency to the point that semi-arid lands not then suitable for cultivation "could be brought into profitable production," further stating that "the deserts themselves could 'blossom as the rose'." A few years later he advanced essentially the same thesis, but this time in the pages of Nature (Idso, 1986) in a brief paper entitled "Industrial Age Leading to the Greening of the Earth." So how has this thesis progressed in the years and decades since as the air's CO2 content has risen to over 400 ppm today?...
