How Dangerous (or uncommon) is a Temperature Rise of 2°C above Preindustrial Values? (12 October 2020) 
A new temperature proxy from the Mediterranean reveals times when temperatures eclipsed the so-called dangerous zone, reaching historic values that were more than 2°°C greater than that observed during recent preindustrial times. Is it any surprise that, rather than harming or destroying humanity, the warmer temperatures actually helped human society to flourish? Such observations indicate it is the height of stupidity to think that humanity could not collectively experience temperatures within the so-called dangerous zone today and not come out on top, especially considering all of the technological advancements that have occurred over the past century...

Exploring African Vegetation Change Since 1982 (9 October 2020) 
Despite increasing in population by 850 million persons and being subjected to the many ecosystem pressures a population increase of that size can cause, and notwithstanding numerous ominous climate-related projections of ecosystem demise from global warming, across large regions of Africa vegetative productivity today has reached the highest values ever observed in the satellite record. And this great greening of Africa has largely been brought about by the very factor alarmists say should be causing a demise -- rising atmospheric CO2!...

Eurasian Snowfall Trends of the Past Two Decades (7 October 2020) 
If global warming is getting worse like alarmists contend, then signs of its predicted effects should be evident all across the globe, including data on snow cover. However, real world data presented in the study examined here reveal nothing of the sort is presently underway...

The Response of the Chilean Oyster to Ocean Acidification and Warming (2 October 2020) 
A decline in seawater pH of 0.3 units, in conjunction with seawater warming of up to 10°C, had no negative physiological impact on this key ecological and economic marine species. In fact, the highest scope for growth value (a measure of the energy available for growth and reproduction) measured in the various treatments was observed under the highest temperature and lowest seawater pH conditions, which observation is just the opposite of what ocean acidification alarmists claim should happen...

Elevated CO2 Diminishes the Growth-retarding Influence of Salinity Stress on Tomato Plants (25 September 2020) 
In light of the positive findings presented in this review, it is likely that crop yields in marginal salt-stressed locations will rise in the future thanks to increasing concentrations of atmospheric CO2, which help to mitigate the growth-retarding effects of this abiotic stress...
