Response of Fish to Ocean Warming -- Summary (31 October 2014)
According to the IPCC, CO2-induced global warming will be net harmful to the world's marine species. This summary examines this hypothesis for various fish species, presenting evidence in opposition to the IPCC's point of view...

Medieval Warm Period (Global) -- Summary (30 October 2014)
Prior to the latter part of the last century, the Medieval Warm Period was universally regarded as just that: a several-century period of warmth during medieval times when the earth was somewhat warmer than it was in the late 1990s. It was also widely acknowledged that the MWP had been preceded by the Dark Ages Cold Period and followed by the Little Ice Age. But even before the new millennium arrived, climate alarmists were attempting to alter climatic history by claiming that the MWP was neither all that warm nor global in scope, in an attempt to portray earth's then-current warmth as being unprecedented over the past one to two thousand years, due to the growing greenhouse effect of ever-increasing anthropogenic CO2 "pollution" of the atmosphere. However, the archives of climate science tell a very different story...

Long-Term CO2 Enrichment Studies (Woody Plants - Sour Orange Trees) -- Summary (30 October 2014)
How long does it take a sour orange tree seedling to achieve a long-term equilibrium rate of growth enhancement in response to a given degree of atmospheric CO2 enrichment? An experiment conducted in Phoenix, Arizona, USA provides the answer for a 300-ppm (about 75%) increase above the urban background value of approximately 400 ppm at the site of the study....

Two Thousand Years of Cyclical Drought in New Mexico, USA (24 October 2014)

Why 2014 Won’t Be the Warmest Year on Record (21 October 2014)
Much is being made of the “global” surface thermometer data, which three-quarters the way through 2014 is now suggesting the global average this year will be the warmest in the modern instrumental record. Dr. Roy Spencer explains why he feels this is wrong...

Mid- and High-Latitude Forests Respond to Environmental Change (20 October 2014)
To "reduce the uncertainties in predicting future carbon dynamics in forest ecosystems, land surface models should not only consider land-use history, but also account for key physiological processes governing the fate of carbon sequestration in forest ecosystems, such as the effects of CO2 fertilization, nitrogen deposition, and climate warming on vegetation growth."...

Historical Diurnal Temperature Range Trends in CMIP5 Models (20 October 2014)
It would seem that "ubiquitous model deficiencies in cloud cover and land surface processes that impact the accurate simulation of regional minimum or maximum temperature changes" are likely responsible for the inability of the models to simulate real-world DTR observations...

Modelling Features of the Indian Summer Monsoon via ECHAM5 (14 October 2014)
This study illustrates the fact that in spite of all that the world's climate modelers have accomplished in many different areas, they have only just begun to traverse the long-and-winding road that leads to ultimate climate modeling success; for as they learn ever more about the various facets of Earth's climatic system, they begin to discover there is even more out there in the 'great beyond' that they must successfully reduce to functionally-correct mathematical expressions that can be incorporated into their computer-driven models...

The Impacts of Hot Days with Night Warming on Small Insect Pests (10 October 2014)
The take-home message of this new work is that although many average or mean temperature models predict increasing pest outbreaks in a warming world, the results of Zhao et al. suggest that "outbreaks of some species might decrease due to the effects of night warming on population dynamics." But try getting a climate alarmist to admit that!...
