Carbon dioxide, nitrogen and climate change are greening the Earth

Carbon Dioxide (“CO2”), also known as “nature’s fertilizer,” has steadily been enriching Earth’s atmosphere, from 320 parts per million in 1970 to 365 parts in 2000, to more than 412 parts today. The evidence of a flourishing planet is plain to see, thanks to satellite imagery that has been monitoring the amount of greenery on the planet since 1979.

As noted in a 2016 Nature study that tracked the changes from 1982 to 2016, although Earth lost some tree cover where forests became farmlands, those losses were far exceeded by new forests. Overall, since 1982, Earth’s tree cover increased by 2.24 million square kilometres, an addition to nature’s bounty of 7.1 per cent.

CO2 fertilisation is only one, albeit a predominant, reason why the Earth is greening. The study also identified climate change, nitrogen fertilisation and land management as other important reasons.

he abstract of the study noted:

Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982–2009.

We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning).

Factorial simulations with multiple global ecosystem models suggest that CO2 fertilisation effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (LCC) (4%).

CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. LCC contributed most to the regional greening observed in southeast China and the eastern United States.

The following was originally published by the United States civil space and aeronautics agency (“NASA”) on 26 April 2016, and updated on 27 March 2019

From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25.
