A rational and logical look at what is reported.... I wish the nature article were not paywalled.

What kind of pollution do you want to feed your plants? The carbon kind. Yet again, a satellite study of leaf area shows that the world is greener than it was in 1982. There are more plants mostly thanks to CO2 aerial fertilization. The biggest benefits from CO2 are in the warm tropics. The extra greenery in colder areas was due to that other disaster called “global warming”. About a tenth of the greening had nothing to do with either carbon pollution or extra warmth and was apparently thanks to nitrogen from man-made fertilizers.

Obviously we need a $10 billion dollar program to stop this immediately.




Humans are Greening planet Earth — ABC

The most comprehensive modelling of remote sensing data so far shows the area on Earth covered by plants in this time has increased by 18 million square kilometres — about 2.5 times the size of the Australian continent — largely due to the fertilising effect of carbon dioxide (CO2).

“[The greening] has the ability to fundamentally change the cycling of water and carbon in the climate system,” said Dr Zaichun Zhu, from Peking University in China and lead author of the new study, which appears today in the journal Nature Climate Change.

Drs Zhu, Canadell and colleagues found that the 46 parts per million increase in atmospheric CO2 between 1982 and 2009 was responsible for 50 to 70 per cent of the observed greening.

“Carbon fertilisation is the dominant process for greening across the globe, particularly in the tropics because there’s so much leaf area there,” Dr Canadell said.

The new study found other causes of the greening, including nitrogen from agricultural fertilisers.

As I keep saying: burn fossil fuels and feed the world.

Plants are so dependent on CO2 that they suck out half the CO2 out of the air before lunchtime each day.
