Earth is growing greener thanks to the increase of one third of emissions of carbon dioxide, indispensable and irreplaceable nutriment of vegetation by photosynthesis. The benefit for crops is emphasized in the context of fighting hunger and increase of world population by ten per cent per decade. The tiny warming related to the airborne fraction of CO2 emissions by each country extrapolated by 2050, the year declared target of “net zero”, remains below the measurability threshold of Earth’s temperature even for the largest emitter. World climate sentinels, Earth’s temperature records, cryosphere, sea level, ocean heat content, oceanic alkalinity, do not discern any catastrophic tendency. Meteorological fluctuations are related to chaotic mechanisms, what implies no predictability on the long term and, therefore, no convincing attribution. The energetic emergency is questioned, in particular a premature transition towards all-electric, found not as “clean” as claimed.
