Regular readers of the Daily Sceptic will be aware of the massive greening of the planet that has occurred over the last 40 years. Alas, this astonishing success story is inexplicably missing from most mainstream Net Zero-focused discourse. This latest paper is written by a group of scientists and published by the U.S.-based educational foundation CO2 Coalition. It is highly technical but it seeks to explain why the nutritional value of the world’s more abundant crops “can and will remain high as atmospheric CO2 concentrations increase towards values more representative of those existing throughout most of Earth’s history”. With CO2 levels considerably higher over most geological history, the current level of 425 parts per million (ppm) is much less than optimum for most plants, the experts observe.
For too long, note the scientists, atmospheric CO2 has been the nutrient in shortest supply holding back plant growth. “Rising atmospheric concentrations of CO2 have clearly been beneficial for the biosphere, agriculture, humanity and particularly for global food security at very low additional cost. Still higher concentrations will bring additional benefits,” they note. The CO2 Coalition, supported by the work of atmospheric scientists like Emeritus Professor William Happer of Princeton, has long argued that CO2 becomes ‘saturated’ at certain levels in the atmosphere. At higher levels its warming properties diminish rapidly. Due to this ‘saturation’, which helps explain why atmospheric CO2 concentrations been up to 20 times higher in the past without the planet turning into a fireball, “man-made CO2 emissions are not capable of triggering dangerous future warming”....<<<Read More>>>...
