A Simple Visual Display of CO2-Induced Wheat Biomass and Water Use Efficiency Increases (25 November 2019)
As illustrated in a graphic accompanying this review, as the air's CO2 concentration rises in the future, the wheat biomass of the two cultivars examined in this study will be improved along with their plant water use efficiency, regardless of nitrogen treatment...
Is Rising Atmospheric CO2 Causing Dangerous Global Warming? (25 November 2019)
Many people are concerned about the potential impacts of rising levels of atmospheric CO2. For years they have been bombarded with claims that unless its concentration is slowed or even reduced, dangerous global warming will ensue, producing all sorts of undesirable consequences with little to no positive effects. Watch this video to lean why this scenario is unlikely to occur and why CO2 is not the all-important driver of temperature that climate alarmists make it out to be...
Do Elevated Levels of CO2 Negatively Impact Human Cognition and Decision Making? (22 November 2019)
In a word, no! And that answer holds through CO2 values ten times above that present in our atmosphere today...

A Warming Climate Enhances Bird Reproduction in Finland (18 November 2019)Data collected on 20 songbirds over the 27-year period 1987-2013 reveals a warming climate had a positive linear relationship on bird reproduction...
The Effects of CO2 on the Nutritive Value of Four Vegetables (15 November 2019)
Higher levels of CO2 improved certain antioxidative properties, of four vegetable known for their high nutritional value: Chinese cabbage, bok choy, young radish and radish. Vitamin C content, for example, was increased by 0.53 to 1.62-fold in response to CO2 increases from 350 to 3650 ppm...
No Significant Trend in U.S. Hurricanes Over the Period 1900-2017 (14 November 2019)
There is no evidence to support the contention that rising levels of atmospheric CO2 are increasing the frequency or severity of hurricanes in the USA. Anyone who makes such a claim is denying the science...

Elevated CO2 Reduces Cadmium Toxicity in a Freshwater Macrophyte (11 November 2019)
High levels of cadmium found in freshwater bodies is detrimental to the growth and survival of many aquatic plant species. But, as the air's CO2 concentration rises in the years and decades ahead, plants will be less susceptible to these growth-retarding influences, courtesy of positive CO2-induced photosynthetic and oxidative enhancements...
Improved Potato Plant Growth and Yield Under Elevated CO2 (8 November 2019)A doubling of CO2 from 400 to 800 ppm induced tuber dry matter increases of 77% and 166% in two cultivars...
The Response of Faba Bean to Elevated CO2 and Soil Water Content (7 November 2019)
In the future, rising atmospheric CO2 will greatly stimulate the growth and yield of faba bean, especially in regions prone to water-stress. And with greater soil water contents thanks to CO2-induced enhancements in plant water-use efficiencies, the quality of faba bean harvest may also improve, especially in water-stressed regions, as the seed N concentration rises under elevated CO2 in consequence of increasing soil water content...

The Combined Impact of Elevated CO2 and Cold Temperature Stress on Spring Wheat (4 November 2019)Low temperature stress during the reproductive stage of wheat can induce yield losses of 10% or more. Fortunately, higher levels of atmospheric CO2 help to mitigate the damages caused by cold temperatures, thereby minimizing those losses...
