The Competitive Advantage of Crops Over Weeds at Elevated CO2 Concentrations (31 July 2017)
Contrary to alarmist contentions, this study demonstrates that crops will fare better than weeds in a CO2-enriched and warmer world of the future...

The Relationship Between Temperature and Emergency Department Visits in China (28 August 2017)
As with nearly all other temperature/human health studies, we find that the effects of cold weather are far more severe and longer lasting than that due to heat...

Struggling to Model Antarctic Surface Air Temperature Trends (27 July 2017)
As the climate-modeling enterprise continues to provide fresh fodder for climate alarmists, it periodically provides evidence for persistent model temperature biases that suggest that such fodder ought not be too highly touted...

An Arctic Copepod is Unaffected by Ocean Acidification (26 July 2017)
Scientists track the growth and development of Calanus glacialis through half of its life cycle and find that this key Arctic species "is tolerant of pH down to at least 7.5 and pCO2 of 1700 µatm"...

Modelling Periods of Significant Saharan Heat Low: How Goes It? (25 July 2017)
As time progresses, efforts to successfully develop new-and-better models of earth's climate periodically appear in the scientific literature, as depicted in the case study here described...

Plant Growth Database (25 July 2017)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Peanut (Ziska et al., 2016). To access the entire database, click here.

Observed Tolerance of Juvenile Blue Crabs to Ocean Acidification (20 July 2017)
Even at pCO2 values that are ten times above the present, the survival, growth duration of the inter-molt period and food consumption level of this important species remain unaffected...

The Relationship Between Ocean Acidification and Net Calcification in a Hawaiian Reef Coral (20 July 2017)
We find yet another study that does not support the ocean acidification scare stories of corals wasting away in the future because of rising atmospheric CO2...

The Resilience of Coastal Marine Ecosystems to Climatic Change (18 July 2017)
In spite of both human-induced perturbations of coastal seawater properties and periodic climatic instabilities, earth's coastal marine ecosystems appear to be able to survive quite nicely...

The Relationship Between Temperature and Human Health in China (17 July 2017)
Extreme cold is far more dangerous to human health than extreme heat...

Plant Growth Database (17 July 2017)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Tomato (Besford, 1993). To access the entire database, click here.

Nitrogen Source Supply as the Root Cause of Protein Decline in CO2 Enrichment Studies (14 July 2017)
A simple retooling of the way in which Nitrogen (N) is supplied to plants in CO2 enrichment studies can change the concentration of N observed in those plants from a marginal decline to a significant increase. And that is great news for those who have worried about the potential impacts of future protein declines on human nutrition, which they have anticipated will occur in the future due to rising atmospheric CO2...

The Interactive Effects of Elevated CO2 and Phosphorus on Soybean Growth (13 July 2017)
Like a miracle fertilizer, CO2 helps to ameliorate the negative impacts of phosphorus deficiency on this important cereal crop...

Interactive Effects of CO2, Drought and Zinc Supply on Wheat (12 July 2017)
Elevated CO2 improves the growth and yield of wheat, ameliorating the negative impacts of drought and low Zn...

The Relationship Between Childhood Bronchitis and Diurnal Temperature Range (10 July 2017)
If global temperatures continue to rise and the diurnal temperature range continues to decline, there will likely be less cases of acute childhood bronchitis in the future...

On the Validity of NOAA, NASA and Hadley CRU Global Average Surface Temperature Data (5 July 2017)
Read about a new study that finds temperature adjustments account for ‘nearly all of the warming’ in climate data sets. Commentary on this new report can be read here. The full report can be accessed here...

How a Coral Reef Fish Might Adapt to Future Global Warming (5 July 2017)
Read on and catch a glimpse of what a number of researchers have learned in this regard...
