Millennial Tree-Ring Chronologies of Northeastern North America (26 November 2014)
Earth's current level of warmth need have nothing at all to do with the rise in the air's CO2 content that accompanied the Industrial Revolution and mankind's expanding usage of fossil fuels...

Effects of Ocean Acidification on Otoliths of Larval Atlantic Cod (26 November 2014)
Under "conditions mimicking global and locally enhanced ocean acidification, otolith growth in Atlantic cod larvae increased," which finding is opposite the concerns of acidification alarmists...

Dying from Cold Spells in Subtropical China (25 November 2014)
Chill out alarmists. A little global warming may well save your life!...

Simultaneous Ocean Acidification and Warming (Effects on Marine Animals: Miscellaneous) -- Summary (25 November 2014)
Most of the ocean acidification research conducted to date has focused solely on the biological impacts of declining seawater pH. Few studies have investigated the interactive effects of ocean acidification and temperature. This summary examines what has been learned in several such studies of various marine organisms that challenge the alarming and negative projections of the IPCC on the matter...

Seawater Acidification by Acid or Atmospheric CO2 Enrichment (24 November 2014)
It can make a big difference to coccolithophores how the acidification is produced...

Global Warming Not Influencing Annual Streamflow Trends in the Southeast and Mid-Atlantic United States (21 November 2014)
Climate model simulations generally predict a future with more frequent and more severe floods in response to CO2-induced global warming. Confirming such predictions with real world observations, however, has remained an elusive task. The latest study to illustrate this point comes from the four-member research team of Barros et al. (2014), who writing in the Journal of Hydrologic Engineering analyzed streamflow records at various locations throughout the southeast and mid-Atlantic United States over the past century...

Plant Growth Database (21 November 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Mongolian Oak (Watanabe et al., 2014)...

How Rising Temperatures Impact the Biodiversity of Small Rodent (20 November 2014)
A study of rodents in semi-arid grasslands of Inner Mongolia "does not support the popular view that global warming would decrease biodiversity in colder and drier regions"...

FACE Experiments (Grassland Species) -- Summary (20 November 2014)
The Free-Air CO2 Enrichment technique of studying the biological consequences of the ongoing rise in the air's CO2 concentration on different types of grasslands growing out-of-doors under close-to-natural environmental conditions reveals the several positive impacts of the anthropogenic-produced phenomenon...

The Double Whammy of Global Warming and Ocean Acidification (19 November 2014)
Is it simply too much for the early life history stages of earth's corals to tolerate? In a word, no!...

Copepods Coping with Real-World Rapid Reductions in Ocean pH (19 November 2014)
They may well have considerable capacity to adapt to future pH decline, such as may occur with ocean acidification because many are "already adapted to pH gradients and shifting pH environments"...

Bamboo: Is It - Like Almost Every Other Plant - a Lover of CO2? (19 November 2014)
After 7 weeks, "plants grown under an elevated CO2 concentration showed an increase of 77% in photosynthesis, 56% in tillering, 104% in leaf area, 92% in height and 91% in total biomass"...

A Test of CMIP5 Models to Predict the Past over Southeast Asia (17 November 2014)
The take-home message of these findings? Even the best of today's climate models fail to do all that their creators - and we their users - feel we should demand of them...

Forest Topsoil Carbon Content: The Outlook for China and Beyond (17 November 2014)
The combination of (1) soil carbon accumulation and (2) vegetation carbon sequestration observed in various locations across the globe is triggering "a negative feedback to climate warming, rather than the positive feedback predicted by coupled carbon-climate models"...

Ocean Acidification (Effects on Marine Animals: Fish) -- Summary (14 November 2014)
As the air's CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, and as more and more carbon dioxide therefore dissolves in the surface waters of the world's oceans, theoretical reasoning suggests the pH values of the planet's oceanic waters should be gradually dropping. The IPCC and others postulate that this chain of events, commonly referred to as ocean acidification, will cause great harm -- and possibly death -- to marine life in the decades and centuries to come. However, as ever more pertinent evidence accumulates, a much more optimistic viewpoint is emerging. This summary examines the topic of the potential impacts of ocean acidification on fish...

Plant Growth Database (14 November 2014)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rye (Dahal et al., 2014)...

Temperature-Related Deaths in a Warming World (13 November 2014)
Over the course of 20th-century global warming, daily minimum temperatures typically rose at a rate that was fully three times greater than the rate of daily maximum temperature rise over most of the world, which resulted in a significant reduction in diurnal temperature range throughout the better part of the inhabited portions of the planet over that time period, which reduction likely significantly reduced the percentage of the human population dying each year from the various health challenges listed in this study...
