Seed Trait Responses of a Prairie Grassland to Warming and Elevated CO2 (20 March 2019)
Based on seed fill, viability, mass and germination data, it appears that there will be little, if any, alteration in the composition of natural prairie Wyoming grasslands in response to rising atmospheric CO2 and temperatures in the future...

Plant Growth Database (19 March 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Crested Wheatgrass (McGranahan and Yurkonis, 2018). To access the entire database, click here.

Minimal Effects of Ocean Acidification on a Marine Barnacle (18 March 2019)
Even at reduced seawater pH levels of 7.5, Amphibalanus amphitrite is resistant to ocean acidification, exhibiting no change in mortality, tissue mass, egg production, adhesion strength, adhesive plaque gross morphology, which shell mass and base plate area were enhanced...

A Holocene Summer Temperature Proxy for Central Quebec (15 March 2019)
Over the past 8,000 years summer temperatures have fluctuated above and below the present mean, revealing the well-known climate anomalies of the Holocene Thermal Maximum, the Medieval Warm Period and the Little Ice Age...

Plant Growth Database (15 March 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for European Aspen (Randriamanana et al., 2018). To access the entire database, click here.

Declining Drought in the USA Over the Past Half-century (14 March 2019)
Climate model projections of more frequent and more severe drought events are not holding true for the conterminous United States, where data reveal a decline in these two parameters over the course of the past half-century...

Combined Impacts of Ocean Acidification and Warming on Yellowfin Bream (13 March 2019)
This important marine fish species is unaffected by ocean acidification, yet its growth is enhanced by elevated temperature...

Plant Growth Database (12 March 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Lemon Tree (Paudel et al., 2018). To access the entire database, click here.

Four Decades of Species Range Change of Sinai's High-Mountain Flora (11 March 2019)
Instead of predicted range contractions and species extinctions, none of the species examined went extinct and the majority expanded their ranges in response to increasing temperatures in this region over the past four decades...

Cycad Growth Enhanced Under Elevated CO2 (8 March 2019)
In the words of the authors of this paper, "the growth and physiological performance of cycads have been severely compromised by declining [CO2] during the Cenozoic Era, possibly contributing to the current rare and endangered status of this functional type." Thankfully for cycads, atmospheric CO2 is on the rise once again...

Plant Growth Database (8 March 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Mongolian Oak (Sun et al., 2018). To access the entire database, click here.

The Non-effects of Ocean Acidification on a Marine Microalgae (7 March 2019)
This study is another in a long line of studies (see the many reviews we have posted on our website under the headings Ocean Acidification and Ocean Acidification and Warming in our Subject Index) showing ocean acidification to be a non-problem...

Temperature-related Human Mortality in Southern New England (6 March 2019)
Deaths attributable to cold weather are over two orders of magnitude larger than deaths attributable to warm weather. What is more, projections of future temperature increase due to global warming will bring a net savings in human lives...

Plant Growth Database (5 March 2019)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rice (Wang et al., 2018). To access the entire database, click here.

The Growth Response of Two Macroalgal Species to Ocean Acidification and Nutrient Supply (4 March 2019)
One species shows no change in response to ocean acidification while the other shows a stimulation of its growth rates, both of which findings run counter to the alarmist narrative that ocean acidification impacts are strongly negative...
