Interactive Effects of CO2 and High Temperature on Nine Wheat Genotypes (30 November 2020)
In a worse-case climatic scenario treatment of elevated CO2 (800 ppm) and high temperature stress (+2.5 °C above ambient), none of the nine cultivars experienced declining grain yields while four experienced significant increases...
Investigating the Major Factors of Wheat Production in India over the Past Four Decades (25 November 2020)Since 1980, annual wheat production in India has increased by 43 Mt, the vast majority of which increase likely came from three factors: rising atmospheric CO2, the application of nitrogen fertilizer and irrigation...

The Growth Response of Maize to CO2 across Two Generations (16 November 2020)
Many positive growth-related enhancements from elevated CO2 increased from one generation to the next, signaling that the benefits of CO2 might be much larger than that reported in thousands of first generation experiments...

Further Evidence the CO2 Fertilization Effect is Presently Enhancing Global Vegetative Productivity (9 November 2020)
Not only has the planet's vegetative productivity increased since the year 2000, its increase has occurred under no additional expense of water, evidenced by a reduction in transpiration and improvement in plant water use efficiency over the corresponding period. What makes these findings even more astounding is the fact that they have ensued despite climate alarmists projections (and claims) to the contrary of widespread global vegetative decline, which they ironically assert should be happening in consequence of rising atmospheric CO2. They could not have got it more backwards!...
A Two-and-a-half Century Winter Temperature Reconstruction from Northern China (6 November 2020)
According to climate alarmist theory, CO2-induced global warming (if it is occurring) should be most evident in high latitude regions during winter months. So, how clear is the signal in this 249-year reconstruction of winter temperatures from northern China?...

The Combined Impact of Warming and CO2 on Peatland Fine-root Growth (2 November 2020)
Rising temperatures led to a strong negative feedback in the carbon cycle where fine-root production increased at a rate of 130% for every degree increase in temperature. Such observations indicate the long-held contention of climate alarmists that warming of peatlands is likely to amplify global temperature by releasing vast amounts of carbon stored in their soils is incorrect...
