The Combined Effects of Elevated CO2 and Temperature on Two Wheat Cultivars (31 October 2018)
According to the authors of this study, the "positive role of CO2 in enhancing photosynthesis of wheat is expected to counteract the negative effect of increase in temperature." And most individuals would consider that consequence an encouraging outcome when it comes to meeting future food security needs...

Plant Growth Database (30 October 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Lentil (Bourgault et al., 2018). To access the entire database, click here.

The Response of Maize to Atmospheric CO2 Enrichment (29 October 2018)
It would appear that maize is carbon-limited at the present-day atmospheric CO2 concentration and will experience larger than anticipated grain enhancements similar to those observed for C3 crops as the CO2 concentration of the atmosphere rises in the future...

Ocean Acidification Enhances the Resilience of Marine Diatoms (26 October 2018)
Elevated CO2 appears to be much more of an asset than a liability when it comes to ensuring the future vitality of marine diatom primary production...

The Positive Response of a Permanent Grassland to Atmospheric CO2 Enrichment (25 October 2018)
Seventeen years of atmospheric CO2 enrichment reveal significant grassland increases in total aboveground biomass, which positive response was not attenuated with time...

The Interactive Effects of CO2 and Phosphorus Supply on Two Wheat Varieties (24 October 2018)
Elevated CO2 concentrations are able to not only mitigate plant carbon limitations, but to also help alleviate the stress of low P. And that feat has great implications for the future of global agriculture, especially in regions where P is limiting on farmland soils...

Plant Growth Database (23 October 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Onion (Bettoni et al., 2017). To access the entire database, click here.

Ocean Acidification Elicits No Cellular Damage in Shark Juveniles (22 October 2018)
Whitespotted bamboo shark juveniles display no significant oxidative damage in response to ocean acidification conditions, suggesting that these top marine predators will maintain their key role in the oceanic food web for centuries to come...

Thirty Years of Increasing Woody Plant Cover in Sub-Saharan Africa (19 October 2018)
Over the period 1986-2016 the woody plant cover of this region has increased by eight percent, despite all the natural and anthropogenic pressures exerted upon it, including war, deforestation and changes in climate...

The Benefits of CO2 on a Potential Feed Crop (18 October 2018)
Growing the aquatic Azolla plant under elevated CO2 concentrations appears to be a viable option for producing sustainable protein feed, as higher CO2 boosts yields without reducing protein levels...

A Preferential Translocation of Carbon into Cucumber Fruit at Elevated CO2 Levels (17 October 2018)
According to the findings reported in this study, under elevated and super-elevated CO2 conditions, greater amounts of carbon were translocated into cucumber fruit from other organs compared to that which occurred in ambient CO2 conditions. And since it is the fruit that matters (because it is what we humans consume), these findings are great news for those who grow and consume cucumbers!...

Plant Growth Database (16 October 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Pepper (Li et al., 2017). To access the entire database, click here.

A Temporal Decline in Spanish Heat-related Mortality (15 October 2018)
Over the 36-year period 1980-2015, and despite a 1.15 °C increase in mean temperature, the relative risk of summer heat-related mortality has declined across Spain, which observation directly contradicts climate alarmist predictions that a warmer climate will increase mortality risk...

A Half-Millennial Record of Rainfall and Runoff in Northwest Australia (12 October 2018)
The modern rise in atmospheric CO2 has likely had no measurable impact on rainfall and runoff in northwest Australia. Modern values of these parameters have been frequently eclipsed (by 15-20% in magnitude) across the long-term half-millennial record. And that reality (one would think) should restrain any climate-alarmist attempt to link any modern rainfall/runoff events or trends in this region with CO2-induced global warming...

Interactive Effects of Elevated CO2 and Salinity Stress on Two Halophyte Species (11 October 2018)
Elevated levels of atmospheric CO2 are found to be effective in offsetting physiological damages due to salinity stress in both and C3 and C4 halophyte (salt-tolerant) species...

A CO2-Induced Stimulation of Shallow Lake Ecosystems (10 October 2018)
As the air's CO2 concentration continues to rise, so too will the gross primary production of the world's aquatic ecosystems, which will enhance the biomass production of lake food webs to support and sustain even greater masses of life...

Plant Growth Database (9 October 2018)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Sunflower (Lakshmi et al., 2017b). To access the entire database, click here.

The Declining Gulf of Maine Cod Stock is Not Driven by Global Warming (8 October 2018)
Climate change is not to blame for the observed cod population decline in the Gulf of Maine despite wrongful claims to the contrary...

Elevated CO2 Improves the Growth, Nutritional and Health Benefits of Two Common Herbs (5 October 2018)
Two herbs recognized for their antioxidant, antibacterial, antifungal, anti-inflammatory, antidiabetic and anticancer activities -- parsley and dill -- respond positively to higher levels of atmospheric CO2. So why are you only now likely hearing about this?...

Two Centuries of Drought in Arid Central Asia (4 October 2018)
There is little indication that drought has increased in frequency and/or intensity in this region over the past two centuries; and the fluctuations it has experienced appear to be driven by natural and not anthropogenic (human-caused global warming) forcings...

The Absent Influence of Ocean Acidification on a Coastal Flatfish (3 October 2018)
The behavior of speckled sanddab fish appears to be immune to changes in pCO2 that are projected for the next century and beyond...
