Elevated CO2 Reduces the Survival Rate of the Confused Sap Beetle
(27 January 2021)
Beetle survival rate was reduced 57% under elevated CO2 rearing conditions in the first generation and by a whopping 98% in the second generation!...

Plant Growth Database (26 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Tomato (Zhou et al., 2020). To access the entire database, click here.
Rapid Adaptation of a Coral Symbiont Algae to Temperature Stress (25 January 2021)
Within the relatively short timeframe of 80 generations (~2.5 years) a coral symbiont algae was able to regulate key genes that enabled it to withstand and adapt to bleaching-relevant temperatures...
1,000 Years of Treeline Change in Northwest Finnish Lapland (22 January 2021)
Since 1930 the modern rise in temperatures during the Current Warm Period has led to a Pinus sylvestris treeline advance that is similar to that observed in the two prior pulses of the past millennium, putting "the recent changes in a long-term context." And that context reveals there is nothing unusual, unnatural or unprecedented about the current level of warmth in northwest Finnish Lapland...

Plant Growth Database (21 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Sorghum (Keramat et al., 2020). To access the entire database, click here.

Recent Trends in Snow Cover Area in the Chitral River Basin of Pakistan
(20 January 2021)
Among the seemingly endless predictions of climate alarmism is the concern that rising temperatures are reducing planetary snow cover. But is this correct?...

Plant Growth Database (19 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Coffee (Avila et al., 2020). To access the entire database, click here.
The Impact of Ocean Acidification on the Behavioral Lateralization of Fish (15 January 2021)
A key study examining the repeatability of studies employing the detour test to discern the effects of exogenous stressors on fish lateralization finds it "does not provide accurate, precise or repeatable estimates," calling into question the results of prior ocean acidification studies utilizing this method...

Plant Growth Database (14 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Potato (Yubi et al., 2020). To access the entire database, click here.

CO2 Fertilization Effects on Global Leaf Area Index
(13 January 2021)
Between 2001 and 2017, nearly 70% of the terrestrial biosphere experienced significant increases in leaf area index values that were caused by rising atmospheric CO2. Such an increase bodes well for the health and well-being of the planet...

Plant Growth Database (12 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Rice (Mao et al., 2020). To access the entire database, click here.

Cold-related Mortality Dwarfs Heat-related Mortality in Portugal
(11 January 2021)
Two decades of temperature and mortality data reveal the attributable fraction of human deaths due to cold weather is 145 times greater than that due to heat...

The Combined Impact of CO2 and Nutrient Supply on Orchid Flowering Quality
(8 January 2021)
A CO2-induced increase in photosynthesis, water use efficiency, the number of lateral branches, flower buds and flower spike length translates into an improvement in flowering quality for the two Phalaenopsis cultivars examined in this study...

Plant Growth Database (7 January 2021)
Our latest result of plant growth responses to atmospheric CO2 enrichment obtained from experiments described in the peer-reviewed scientific literature is for Grapevine (Wohlfahrt et al., 2020). To access the entire database, click here.

The Photosynthetic Response of Eggplant to CO2 Enrichment
(4 January 2021)
Gene sequencing identified a number of biological processes, cellular components and molecular functions that were responsible for CO2-induced increases in plant photosynthesis and growth...
A CO2-induced Mechanism for Alleviating Growth Restrictions in Phosphorus-limited Ecosystems (30 December 2020)
A new study suggests global net primary productivity (NPP) may well never be limited by soil phosphorus in a world of increasing CO2 concentrations...
