No Impact of Elevated CO2 on Learning Capabilities of Bigfin Reef Squid
(29 January 2021)
Under a worse-case CO2 emission scenario (seawater of 1,084 µatm), learning and the capacity for conditional discrimination are unaffected in bigfin reef squid, indicating complex or higher level learning of this important cephalopod species will not be impaired by projections of future ocean acidification...

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!...

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...

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?...

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...

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...

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...
