44 Years of Precipitation Change in the Peruvian Altiplano (14 August 2020)
An examination of 11 precipitation indices from 15 locations in the Peruvian Altiplano reveals there is no evidence rising atmospheric CO2 is having any current impact on precipitation in this region...

Plant Growth Database (13 August 2020)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Deciduous tree species (Souza et al., 2019). To access the entire database, click here.

Soil Respiration Under a Combination of CO2, Nitrogen and Cd Treatments in a Model Forest
(12 August 2020)
In all of the treatment combinations examined by the authors of this study, annual soil respiration decreased between 15 and 34% compared to control conditions, indicating an overall increase of soil carbon sequestration...

The Interactive Effects of CO2 and Arbuscular Mycorrhizal Fungi on Oregano
(10 August 2020)
In summing up the results of this paper, the authors write the application of elevated CO2 and arbuscular mycorrhizal fungi are "reliable techniques that can be used to improve growth and the nutritive and medicinal values of oregano, however their synchronous application is much more beneficial." Such a conclusions, they add, is "supported by the improved photosynthesis, nutrients uptake, biomass production and higher accumulation of primary (sugars, amino acids, fatty acids and organic acids) and secondary (phenolic acids and flavonoids) metabolites." With studies like this, it is easy to recognize the undeniable fact that atmospheric CO2 is not a pollutant, but an important aerial fertilizer capable of enhancing both the quantity and quality of Earth's vegetation...

The Combined Influence of Temperature and CO2 on Powdery Mildew Disease in Zucchini
(7 August 2020)
The authors of this study conclude increases in CO2 concentration and temperature will not likely influence the efficacy of current management strategies against powdery mildew disease on zucchini...

Over Four Decades of Coral Reef Resilience in the Eastern Tropical Pacific
(5 August 2020)
After repeated thermal stress disturbances, such as those caused by major El Niño events, coral reefs in this section of the ocean have demonstrated "regional persistence and resiliency"...

Long-term Trends in Global Gross Primary Productivity
(3 August 2020)
Rather than declining in vigor as so many climate alarmists falsely claim, the world's land vegetation is increasing its robustness, and has been doing so for over at least the past eleven decades...

The Effects of CO2 on the Growth and Mineral Concentration of Three Leafy Greens
(31 July 2020)
Under hydroponically-grown conditions, basil, lettuce and Swiss chard experienced dry weight gains of 26%, 25% and 48%, respectively, in response to a 390 ppm increase in atmospheric CO2. Various plant mineral concentrations remained mostly unaffected...

A Field-based Analysis on the Impacts of Ocean Acidification on Pacific Oyster Reproduction (29 July 2020)
Policy makers should not place too much faith in findings attained from laboratory-based studies on the subject of ocean acidification. In the real world, what might appear to be a problem in the laboratory is often of little or no consequence in nature...
