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)
How well does the newest batch of climate models replicate what is known about old climates? At the end of the day, it appears that there is still a "need for continued efforts by modelling groups to achieve accurate simulations of fundamental climate processes"...

Mussels Flex Their Muscles when Temperature & OA Both Increase (9 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"...

Barley Seedlings Seeking Needed Nutrients in Saline Soils (8 December 2014)
Under "combined conditions of salt stress and elevated CO2, barley seedlings were able to maintain increased uptake and translocation rates for almost all nutrients"...

Plant Growth Database (6 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 Sweet Pepper (Piñero et al., 2014)...
