[Ed. – Climate alarmists would rather keep this under their hat.]
Global greening is the name given to a gradual, but large, increase in green vegetation on the planet over the past three decades. The climate change lobby is keen to ensure that if you hear about it at all, you hear that it is a minor thing, dwarfed by the dangers of global warming. Actually, it could be the other way round: greening is a bigger effect than warming.
It is a story in which I have been both vilified and vindicated. Four years ago, I came across an online video of a lecture given by Ranga Myneni of Boston University in which he presented an ingenious analysis of data from satellites. This proved that much of the vegetated area of the planet was getting greener, and only a little bit was getting browner. In fact, overall in 30 years, the green vegetation on planet Earth had increased by a rather extraordinary 14 per cent. He said this was occurring in all vegetation types — from tropical rainforests to arctic tundra.
What was responsible for this ecological good news? He credited rising carbon dioxide concentrations in the atmosphere. …
