As the Earth transited from the bitter cold of the Little Ice Age to the welcome warmth of the Current Warm Period, storminess declined significantly...

A Three-Decade History of Australian Region Tropical Cyclones (27 February 2015)
Once again, we have another example wherein the claims of proponents of CO2-induced increases in the number of occurrences of various extreme weather events do not appear to jibe with what is observed in the real world of nature...

The Many Impacts of Global Warming on Human Health (24 February 2015)
A new literature review confirms that a decline in the diurnal temperature range (DTR) leads to decreases in both human morbidity and mortality, which findings almost make one want to wish for a little CO2-induced global warming because it historically has led to reductions in the DTR...

Modelling the Seasonal SST Cycle of the Eastern Equatorial Pacific (24 February 2015)
In order to improve the capability of the CGCMs in simulating a realistic SST seasonal cycle in this region, SST biases that exist in both CMIP3 and CMIP5 CGCMs, such as the climatological simulation of the cold tongue region and the southeastern tropical Pacific, must be resolved...

FACE Experiments (Experimental Artifacts) -- Summary (23 February 2015)
Free-Air CO2 Enrichment or FACE studies of the effects of higher-than-normal concentrations of atmospheric CO2 on the growth and development of plants have long been considered to be the most realistic type of experimental route to determining the likely biological consequences of the ongoing rise in the air's CO2 content, providing minimal alterations (it was thought!) to the natural environment of the plants. But now a new paradigm has turned the old one on its head....

165 Years of Mangrove Tree Responses to Rising Atmospheric CO2 (23 February 2015)

A little global warming could do a lot to reduce health-related hospitalizations of metropolitan living Koreans...

Do Acidifying Oceans Portend the Eventual Demise of Copepods? (18 February 2015)
Eight curious researchers conducted an enlightening study in an attempt to answer this question, finding that copepods likely have an adaptive potential to withstand "the direct long-term effects of even the more pessimistic future ocean acidification scenarios"...

The Positive Impact of Elevated CO2 on Sunflower Seed Production (17 February 2015)
Just as is found for most all food crops, the yield of sunflower seed oil is significantly enhanced by atmospheric CO2 enrichment, as is the quality of the oil...

Carbon Sequestration in Forest Soils: The Role of Added Nitrogen (17 February 2015)
Does it help or hinder? ... or does it play no significant role at all? It does. In this study of two temperate forest stands it was found that "nitrogen-induced soil carbon accumulation is of equal or greater magnitude to carbon stored in trees"...

The Accelerating Growth Rates of Central European Forest Stands (13 February 2015)
For the past 140 years they have been significantly increasing, and doing so in spite of extended periods of both acid rain and drought conditions...

Extinction (The Possibilities for Stationary Plants) -- Summary (13 February 2015)
In addition to migrating to more suitable locations, Earth's plants have other ways of successfully responding to various pressures that might otherwise lead to their extinction...

Medieval Warm Period Project (13 February 2015)
The latest Medieval Warm Period Record comes from tree ring records obtained from near the West Coast of Norway up through the Kola Peninsula of NW Russia...

Plant Growth Database (13 February 2015)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wild Rye (Li et al., 2014)...

The Ecosystem Services of Seagrass Beds in a CO2-Enriched World (11 February 2015)
The CO2-prompted ocean-acidification-induced increases in the many and varied benefits of seagrasses - along with their monetary value - may truly surprise you, approximately 500 and 600 billion pounds sterling ($765-918 billion USD)...

Effects of CO2 Enrichment on Roots of a Warm Temperate Forest (10 February 2015)
A CO2-induced increase in fine root exploration by trees may be "a primary means for [their] acquiring additional soil resources under elevated CO2" that "has the potential to facilitate increased soil resource uptake allowing for a sustained response to elevated CO2." And this fact could well be one of the chief reasons for the ultimate undoing of the once highly-hyped progressive nitrogen limitation hypothesis...

Simulating Equatorial Pacific SST, Wind Stress and Surface Fluxes (10 February 2015)
CMIP5 models are still falling short of adequately reproducing even past states of the three climate characteristics....

Leaf Carbon Gain by a Tree Seedling in a Tropical Rain Forest (9 February 2015)
How are the leaves of the highly-shaded understory trees ever able to survive - and even thrive - in an environment where life-giving light is much reduced in both intensity and availability? Here's a hint, it has something to do with atmospheric CO2...

GCM Predictions of North India Winter Precipitation for Its Crops (9 February 2015)
Present-day general circulation models are not up to the task of providing what is needed to properly project future yields....

CMIP5 Modeling of the Western Tropical Pacific Climate System (6 February 2015)
While models "are now sufficiently reliable to provide useful insights into many aspects of the climate system in the region, systematic biases in the simulation of some important features in the Pacific region persist." And as for the significance of these many biases in the current crop of CMIP5 models, one can get a sense of their importance in Grose et al.'s concluding opinion that "all projections must account for the uncertainty introduced by the presence of these biases"...

1900-2012 Warming of Washington, Oregon, and Northern California (6 February 2015)
Will the real reason for the warming please stand up! It will, and it is NOT anthropogenic in origin....

Agriculture (Species: Strawberry) -- Summary (5 February 2015)
Increases in the air's CO2 content will benefit the growth and production of strawberry plants in a number of ways. It is therefore a shame when government organizations such as the United Nations Intergovernmental Panel on Climate Change or the U.S. Environmental Protection Agency fail to sufficiently acknowledge such benefits and instead forge ahead with efforts that would mute them when they should be promoting them...

Plant Growth Database (5 February 2015)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Wheat (Benlloch-Gonzalez et al., 2014)...

576 Years of Droughts and Floods Along Utah's Wasatch Front (4 February 2015)
How do the extremes of the last century compare with those of prior centuries? Based on the data, we are essentially forced to conclude there has not been anything unusual, unnatural or unprecedented about the duration, magnitude or intensity of droughts and floods along the Wasatch Front and throughout the Intermountain West of the United States over the period of time during which the world's climate alarmists stubbornly contend the Earth warmed at an unprecedented rate due to the greenhouse effect of ever-increasing anthropogenic CO2 emissions...

Modelling the Long (MAM) and Short (OND) Rains of East Africa (4 February 2015)
The long and the short of it is that fully-coupled CMIP5 climate models are still not up to the task of replicating past histories of the two phenomena. And that is a pretty sad summation of an enterprise that has gobbled up billions of tax dollars with nothing to show for it...

Herbivores Enhance the Carbon Flux to CO2-Enriched Forest Soils (3 February 2015)
It would appear that the outwardly-negative activity of insect herbivores chomping on tree leaves may have a number of hidden (below-ground) positive consequences, which become even more positive as the air's CO2 content continues its temporal upward trajectory...

The Challenges of a Putative Alien Coral in the Mediterranean Sea (3 February 2015)
Another paper demonstrates that Earth's corals appear to be a whole lot more resilient than what the world's climate alarmists make them out to be...

Representations of Aeolian Dust in CMIP5 Climate Models (3 February 2015)
An evaluation of atmospheric dust in 23 state-of-the-art global climate models used in the IPCC's Fifth Assessment Report reveals that "all models fail to reproduce basic aspects of dust emission and transport over the second half of the twentieth century," casting "doubt on the representation of other features of coupled Earth systems that are affected by aeolian dust, including regional land and ocean surface temperatures, precipitation and cloud processes, coupled equatorial processes, and terrestrial and oceanic biogeochemistry"...
