Further Empirical Proof Elevated CO2 is Benefitting Earths Forests (31 May 2017)
Model-based assertions that the predicted negative impacts of climate change will overpower any positive influence of rising atmospheric CO2 on forests could not be more wrong!...

Four Decades of Seagrass Stability in the Puget Sound Estuary (30 May 2017)
Despite a doubling of local human population and forty years of anthropogenic environmental concerns, including the likes of global warming and ocean acidification, seagrass area in this coastal community has remained remarkably stable...

A Two Century Hydrologic Reconstruction from Turkey (29 May 2017)
There is little evidence that rising atmospheric CO2 concentrations, and their theorized accompanying global warming, are having any impact on Turkish droughts and floods...

A Reduction in US Drought Over the Period 1901-2014 (25 May 2017)
Instead of making droughts worse, the global warming/climate change experienced over the past century appears to have ameliorated it...

More Evidence that Rising Atmospheric CO2 and Temperature Benefit Earth's Forests (24 May 2017)
A new study of Smith fir trees near the timberline of the southeastern Tibetan Plateau shows large increases in basal area increment and intrinsic water use efficiency over the past century in response to both rising temperatures and atmospheric CO2...

One Thousand Years of Drought on the Southeastern Tibetan Plateau (24 May 2017)
What does it reveal about the status of droughts recorded during the instrumental period?...

A New Analysis of European Sea Level Rise (22 May 2017)
The results of this study do not bode well for climate alarmists who have underpinned their surety of the future on model projections of sea level rise that fail to match reality...

An Absence of Trends in Extreme Sea Levels in the Pearl River Estuary (19 May 2017)
Despite a 30 percent rise in atmospheric CO2, there appears to be no anthropogenic impact on extreme sea levels in this region over the past several decades...

Indirect Positive Effects of Ocean Acidification Can Overpower Sometimes Observed Direct Negative Effects (18 May 2017)
Although ocean acidification might be shown to directly harm a marine organism in a simple laboratory experiment, out in the real world its indirect benefits may well be sufficient to completely ameliorate and overpower any negative direct effects...

Elevated CO2 Improves the Growth and Yield of Broomcorn Millet (18 May 2017)
Higher amounts of CO2 in the atmosphere will improve the yield of this important regional crop and provide economic benefits to low income farmers who grow it -- unless climate alarmists have their way to keep them from accruing...

Elevated CO2 Improves Growth and Essential Oil Production in Lippia alba (16 May 2017)
Essential plant oils are often utilized for their medicinal purposes and elevated CO2 can help to improve their production...

The Interactive Effects of Elevated CO2 and Drought on Plant Biomass, Nutrient Content and Nutrient Concentration of a Herbaceous Grass (15 May 2017)
The results of this study reconfirm what numerous other studies have found - that the benefits of rising atmospheric CO2 on plant growth (1) are real, (2) that they are often fully capable of ameliorating environmental stresses such as drought, and (3) that they tend to improve the acquisition and efficient use of plant nutrients such as nitrogen and phosphorus...

Sea Ice Expansion in the Southern Hemisphere: Another Reason to Abandon Federal Global Warming Policy (11 May 2017)
Climate models project significant declines in Antarctic sea ice in response to CO2-induced global warming. However, sea ice extent and area have both increased in the Southern Hemisphere over the past four decades despite a 20 percent increase in atmospheric CO2...

Is it global warming or global cooling that has taken the greater toll?...

Responses of Two Coral Species to Elevated CO2 and Temperature (10 May 2017)
As Earth's climate warms and the air's CO2 concentration continues to rise, the planet's corals appear to be making certain life-style changes that enable them to successfully deal with the two phenomena...

How have these important ecosystems responded to the so-called unprecedented rise in CO2 and air temperature over the past few decades?...

Is Renewable Energy an Economic Boon or Bust in Addressing Global Warming Concerns? (3 May 2017)
Climate alarmists frequently call for a reduction in energy production via fossil fuel sources by increasing the share of so-called low carbon renewable energies, such as wind, solar and biomass. By so doing, they posit there will be a reduction in CO2 emissions (which emissions they contend are causing dangerous global warming) and that this reduction will come with little to no economic harm. But is that truly the case?...

The Increasing Sea Ice of the Southern Ocean (1992-2008) (2 May 2017)
Despite being the one place on Earth where global warming is supposed to rear its ugly head first and foremost, sea ice area and extent have been increasing in the Southern Ocean over the past two decades...
