We should welcome the fact that CO2 has risen to “levels not seen on Earth for millions of years,” even if the “fact” is less certain than you might believe. Plants have been trying to cope with a CO2 famine for millions of years, a famine that is finally ending. With self-assurance worthy of Dr. Pangloss, the article implies that pre-industrial CO2 levels, around 280 ppm, were the “best of all possible worlds.” But 280 ppm is much closer to (sea-level) starvation levels of about 150 ppm, when many plants die, than to the optimum levels for plant growth, which greenhouse operators already know are greater than 1000 ppm. There is fossil evidence of CO2 starvation at the end of the last ice age, when CO2 levels dropped to below 200 ppm. Even today’s 400 ppm is far too low for optimum plant growth.
Hulme: "January 12021, a new World Meteorological Organisation (WMO) climatological standard normal came into effect. The ‘present-day’ climate will now formally be represented by the meteorological statistics of the period 1991-2020, replacing those from 1961-1990. National Meteorological Agencies in member states are instructed to issue new standard normals for observing stations and for associated climatological products. Climate will ‘change’, one might say, in an instant; today, the world’s climate has ‘suddenly’ become nearly 0.5°C warmer. It is somewhat equivalent to re-setting Universal Time or adjusting the exact definition of a metre." ...
"So, what is the significance of the move to a new 1991-2020 WMO normal in January 2021? On the one hand, it is a pragmatic move to redefine ‘present-day’ climate for operational applications to that of the most recent 30-year period. On the other hand, it puts into play a third climatic baseline. Already existing is the ‘pre-industrial’ climate of the late nineteenth century and the ‘historic’ climate’ of 1961-1990, the latter about 0.3°C warmer than the former. And now there is the new ‘present-day’ climate of 1991-2020, in turn about 0.5°C warmer than the ‘historic climate’ of 1961-1990." ...
"Combining a climatic tolerance of 2°C—or indeed 1.5°C—with a pre-industrial baseline yields a very different climate target than, say, using a 1986-2005 baseline, the period widely adopted by IPCC AR5 Working Group I as their analytical baseline. The choices of both baseline and tolerance are politically charged. They carry significant implications for historic liability for emissions (La Rovere et al., 2002), for policy design (Millar et al., 2017) and for possible reparations (Roberts & Huq, 2015)."
Christopher Monckton: "At long last, following the warming effect of the El Niño of 2016, there are signs of a reasonably significant La Niña, which may well usher in another Pause in global temperature, which may even prove similar to the Great Pause that endured for 224 months from January 1997 to August 2015, during which a third of our entire industrial-era influence on global temperature drove a zero trend in global warming. ... As we come close to entering the la Niña, the trend in global mean surface temperature has already been zero for 5 years 4 months.
However, the new Pause is at a surface-temperature plateau 0.3 C° above the old Pause."
Scientists continued defying the “unprecedented” global warming narrative by publishing nearly 150 papers in 2020 that show large regions of the Earth (a) haven’t warmed in recent decades, (b) were as-warm or warmer within the last several centuries, and/or (c) were 1-7°C warmer than today just a few millennia ago.
Greanpeace co-founder Dr. Patrick Moore: "What a farce the IPCC Paris Accord and all previous 'agreements' to reduce CO2 emissions have been. If only the collective billionaire-class would recognize that CO2 is entirely beneficial we could get on with making the world a better place."
