Elevated CO2 Overpowers the Effects of Drought in Wheat (30 July 2018)
Rising concentrations of atmospheric carbon dioxide will increase the yield of wheat, even during times of moderate to severe drought (relative to well-watered and ambient CO2 conditions of today). And on those rare instances of extreme drought, wheat yields of tomorrow should still be similar to those observed under well-watered conditions of today, thanks to the incredible molecule -- CO2 -- that we like to call the elixir of life!...
The Outer Reefs of Moorea Island: Back From the Dead! (27 July 2018)
Despite suffering two major disturbance outbreaks over the past three decades, coral cover on the outer reef slope has remarkably recovered to pre-disturbance levels...
The Combined Effects of Elevated CO2 and Water Deficit on Cacao (26 July 2018)
According to the authors of this study, the "positive effect of CO2 may ameliorate growth reductions caused by water limitation in the future," which "could potentially improve pod yields [of cacao] by supporting a larger number of pods per tree." And that is sweet news for the farmers who grow -- and the consumers who utilize -- cacao for its confectionary delights!...
Elevated CO2 Alleviates the Negative Effects of Drought Stress in Cucumbers (25 July 2018)
By improving photosynthetic performance and inducing changes in leaf tissue structure, elevated CO2 reduces the negative effects of drought in this important crop...

The Positive Growth Responses of Winter Cherry to Atmospheric CO2 Enrichment (23 July 2018)
As the air's CO2 content continues to climb, this perennial shrub will experience increases in plant photosynthesis, net primary productivity, root, stem and leaf biomass, and water use efficiency...
The Changing Relative Risk of Heat-Related Mortality in Spain (20 July 2018)
Over the past three decades, the relative risk of heat-related mortality in Spain has declined from a value of 1.15 to a value of 1.01. Thus, heat waves are presently exerting no statistically significant influence on human mortality despite model claims that they should be...
The Impacts of Elevated CO2 on Basil and Peppermint (19 July 2018)
The results of this study are quite encouraging, demonstrating the ability of rising atmospheric CO2 to not only increase the growth and biomass of these two herbs, but to also improve their medicinal value. Unfortunately, about the only place you will hear or learn about these positive findings is here on our CO2 Science website...
Elevated CO2, Nitrogen Fertilization and Irrigation Regime Impacts on Tomato (18 July 2018)
It appears that rising concentrations of atmospheric CO2 will enhance not only the quantity, but also the quality, of future tomato yields...

The Combined Effects of Elevated CO2 and Drought on Yellow Poplar Seedlings (16 July 2018)
A 210 ppm enrichment of atmospheric CO2 was strong enough to fully ameliorate the adverse effects of water shortage on this important timber species...
Impacts of Elevated CO2 on Lead Contaminated Soils (13 July 2018)
At higher atmospheric CO2 concentrations, black locust seedlings removed greater amounts of lead from lead-contaminated soils...
A Freshwater Macrophyte's Response to Elevated Temperature and Elevated CO2 (12 July 2018)
Even under quite extreme, and unrealistic, temperature and atmospheric CO2 conditions of +4.5°C and +850 ppm above ambient, this aquatic plant responds positively by producing greater mass...
The Interactive Effects of Elevated CO2 and O3 on Chinese Tallow Tree (11 July 2018)
The positive growth effects of CO2 enrichment were powerful enough to fully ameliorate the biomass reductions induced by elevated O3...

Projections of Future Peanut Yields in Senegal (9 July 2018)
When the positive impacts of elevated CO2 on crop growth are included, simulations of future climate change return "modest positive increases in peanut yields for Senegal"...
The Effects of Elevated CO2 and Temperature on Rice Nutrient Levels (6 July 2018)
Results of this analysis indicate there was no clear trend or signal to support the notion that any of the plant nutrition measures analyzed by the authors (plant nutrient concentration, plant nutrient content or nutrient use efficiency) will significantly change in a world of both rising temperature and atmospheric CO2...
The Capacity of a Damselfish to Adapt to Ocean Acidification (5 July 2018)
When scientists allow for adaptation and incorporate real-world examples of such into their ocean acidification studies (e.g., developmental plasticity and/or transgenerational acclimation), the negative outcomes observed under acute CO2 treatments are lessened or absent, as observed in the present study. Recognizing these facts, and the much longer period of time that species will have to adapt (and even evolve) to rising CO2 levels in the future, it is abundantly clear that the presently-espoused alarmist view of ocean acidification harming marine life and driving species toward extinction is premature and unrealistically negative. And it will remain in this sorry state until there is an adequate amount of research conducted to incorporate the adaptive and evolutionary response of marine organisms to elevated CO2 across multiple generations...
The Impact of Elevated CO2 on Arabidopsis (4 July 2018)
In addition to enhancing several growth-related parameters, elevated CO2 increases the carotenoid content in recently emerged younger leaves...
The (Non) Effect of Elevated Atmospheric CO2 on Human Cognitive Performance and Decision Making (3 July 2018)
From time to time, concerns emerge in the global warming debate that rising atmospheric CO2 is directly harming human health and/or impairing cognitive performance. The present review highlights research examining the latter of these two claims, finding that, even at values more than 36 times the present CO2 concentration of the atmosphere there is no discernible CO2 effect on human cognitive performance or decision making...
