Response to Heat Stress in the United States: Are More Dying or Adapting? (30 December 2014)
A new study finds the U.S. population has "become more resilient to heat over time" - in this case from 1987 to 2005 - led by the country's astute senior citizens...

Health Effects (Temperature - Hot vs. Cold: Asia) -- Summary (30 December 2014)
Climate alarmists predict global warming will increase human death rates, and nary a heat wave occurs but what they are quick to blame any concurrent excess deaths on the high temperatures associated with it. Much more deadly than hot weather, however, is cold weather; yet climate alarmists typically ignore the excess deaths that are caused by low temperatures, even though they are far more numerous than those caused by high temperatures. In the present summary we examine a number of papers investigating the relationship between temperature and human health for various locations in Asia...

Carbon Dioxide Enrichment Propagates Success in Protea cynaroides (29 December 2014)
Higher CO2 aids the growth of plantlets producing the national flower of South Africa...

Global Warming and World Food Security (29 December 2014)
Global warming - if it is ever to begin again following its current 18-year hiatus - may very well prove providential in terms of boosting crop yields and enhancing food security, which is a much more optimistic assessment than that presented by the IPCC...

Courageous Copepods Coping with Catastrophic Climate Change (29 December 2014)
Day in and day out, literally, they encounter and successfully deal with climate changes equivalent to those that state-of-the-art climate models project for the end of the current century...

Of Floods and Paleofloods Along the Middle Yellow River of China (24 December 2014)
The degree of Yellow River flooding experienced in China over the last few decades - when the world's climate alarmists claim the Earth experienced unprecedented global warming - was likely nowhere near what was experienced there some 16 to 18 centuries ago, which additionally suggests that either the planet's current level of warmth may also be nowhere near what it was at that time, or that warming does not necessarily lead to greater flood events...

Insect Herbivory of Understory Plants in a Future Warmed World (24 December 2014)
A new study suggests that global warming is not likely to alter the magnitude and/or pattern of herbivore pressure on host plants...

How Well Do Current Models Simulate Holocene Climate Change? (23 December 2014)
One would presume they would do so quite well; but one finds something far different when the models are actually put to the test of attempting it...

Responding to Temperature Stress: The Thermal Adaptation of Coral Reefs -- Summary (23 December 2014)
As living entities, corals are not only acted upon by the various elements of their environment, they also react or respond to them. And when changes in environmental factors pose a challenge to their continued existence, they sometimes take major defensive or adaptive actions to insure their survival. A simple but pertinent example of one form of this phenomenon is thermal adaptation, which feature has been observed by several researchers to operate in corals in response to the stress of high temperature. This summary presents a review of their work...

Extreme Precipitation Events on the Loess Plateau of China (22 December 2014)
Real world data once again refuse to conform to the climate-alarmist claim that all types of extreme weather are becoming both more extreme and more frequent at one and the same time...

Two Thousand Years of Northern European Summer Temperatures (17 December 2014)
A new proxy temperature history depicts "a long-term cooling trend of -0.30°C per 1,000 years over the Common Era in northern Europe," revealing there is nothing unusual, unnatural or unprecedented about the Earth's current level of warmth...

Daytime-Only vs. 24-Hour Atmospheric CO2 Enrichment (17 December 2014)
New evidence reveals that studies which "only elevate CO2 during the daytime could underestimate crop responses to future CO2 concentrations"...

A Coral Species from Australia That Can Survive Serious Bleaching (16 December 2014)
According to the authors of this study, "some coral species will be able to adapt to, and survive, the increasing stressors expected with future climate change"...

Hurricane Surge Risk in Northwest Florida, USA (16 December 2014)
Has it risen in step with the warming of the past century? No. Wwhereas the mean return period of surges greater than five meters is about 400 years based on what can be learned from historical records, it is only a mere 40 years based on paleo-reconstructions, which is essentially just the opposite - and by a full order of magnitude - of what we typically hear from those who preach that climatic salvation resides in our dramatically curtailing our usage of fossil fuels...

Growth Response to CO2 (Forests) -- Summary (16 December 2014)
Forests contain perennial trees that remove CO2 from the atmosphere during the process of photosynthesis and store it's carbon within their woody tissues for decades to periods sometimes in excess of a thousand years. Thus, it is important to understand how increases in the air's CO2 content affect forest productivity and carbon sequestration, which has a great impact on the rate of rise of the air's CO2 concentration. In this summary, therefore, we review several scientific publications pertaining to these subjects...

Satellite-Derived Assessments of Trends and Patterns of Drought (11 December 2014)
Apparently, the Earth missed the extreme weather memo -- the one from climate alarmists that says droughts should be increasing due to CO2-induced global warming. A new observation based study by Damberg and AghaKouchak (2014) reveals that "the area of global land under drought conditions does not show a significant trend over the past three decades"...

Plant Growth Database (11 December 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Mulberry (Sekhar et al., 2014)...

Extreme Weather at Its Worst: The Heat and Drought of AD 1540 (10 December 2014)
The double-barreled weather extremes of 1540 make the 2003 heat waves and droughts of Western Europe - and those of Russia in 2010 - feel like a walk in the park...

Testing PMIP2 and CMIP5 Models Against Climates of the Past (10 December 2014)

Mytilus galloprovincialis "may be able to tolerate increasing pCO2 and decreasing aragonite saturation state across the wide range of temperatures they naturally experience in the field, with moderate warming offsetting potential reductions in growth associated with OA"...

Indian Summer Monsoon Rainfall in General Circulation Models (9 December 2014)
Introducing their study of monsoonal rainfall over India, Nair et al. (2014) note that atmospheric general circulation models (GCMs) have historically had "serious difficulties in correctly reproducing monthly or seasonal precipitation," and, therefore, they set out to further explore what advances may have been made in this area of climatological research over the intervening six years...

Modeling Atlantic Tropical Cyclones Associated with Pacific ENSOs (8 December 2014)
How well do the most up-to-date climate models perform in this regard?...

A New Method of Assessing the Rate of Global Sea Level Rise (8 December 2014)
Results indicate a mean global sea level rate-of-rise value of 1.5 ± 0.5 mm/year, inferred from "a weighted average of the hemispheric trends according to the area they represent," which finding "challenge[s] the widely accepted value of global sea level rise for the twentieth century"...

Assessing Possible Climate Change Impacts on Chinese Food Supply (3 December 2014)
Overall, Chinese agriculture appears to be relatively resilient to climate change, which is a significant finding for the world's most populous country in being able to adequately feed its inhabitants at the midpoint of the current century...

Carbon Dioxide Enrichment of Peach Trees: How Sweet It Is! (2 December 2014)
In our all-too-politically-correct world, carbon dioxide (CO2) frequently gets a bad rap, demonized for its potential and unproven effects on climate. However, if the truth be told, carbon dioxide is a magnificent molecule, essential to nearly all life on Earth...
