Planting 0.9 Billion hectare of trees could avert AGW

That's about 15% of usable arable land.

But its cheaper than technological solutions to sequester carbon.

Massive Forest Restoration Could Greatly Slow Global Warming
The right trees, planted in the right locations, could store 205 gigatons of carbon dioxide

We have heard for years that planting trees can help save the world from global warming. That mantra was mostly a statement of faith, however. Now the data finally exist to show that if the right species of trees are planted in the right soil types across the planet, the emerging forests could capture 205 gigatons of carbon dioxide in the next 40 to 100 years. That's two thirds of all the CO2 humans have generated since the industrial revolution. "Forest restoration is by far our most powerful planetary solution today," says Tom Crowther, a professor of global ecosystem ecology at the Swiss Federal Institute of Technology in Zurich, and an author of a study published Thursday in Science that generated the eye-opening number.

The study team analyzed almost 80,000 satellite photo measurements of tree cover worldwide and combined them with enormous global databases about soil and climate conditions, evaluating one hectare at a time. The exercise generated a detailed map of how many trees the earth could naturally support—where forests grow now and where they could grow, outside of areas such as deserts and savannahs that support very few or no trees. The team then subtracted existing forests and also urban areas and land used for agriculture. That left 0.9 billion hectares that could be forested but have not been. If those spaces were filled with trees that already flourish nearby, the new growth could store 205 gigatons of carbon by the time the forests mature.

After 40 to 100 years, of course, the storage rate would flatten as forest growth levels off—but the researchers say the 205 gigatons would be maintained as old trees die and new ones grow. There would be "a bank of excess carbon that is no longer in the atmosphere," Crowther says.

Bamboo is faster growing. However, need to plant enough to keep pace with deforestation in the Amazon before actually reducing atmospheric/ocean CO2.

In principle I am all for it but think it is rather a bigger task than you might think.

The trees should be plantation timber harvested regularly—mature forests have a methane plume above them.

Can we stop farmers clearing land? The Amazon?

Trees planted on ridges, esp native trees, can increase rainfall.

One would think that together with this , all clearing in Sth American, and Australian, and SE Asian Rainforests must cease , immediately.
If it means the rich world pays the poor of these nations to stop, surely that is a better thing, than to keep on with this destruction. it's all for profits, no other eason,, so WE should offer them money to STOP.

Of course it is hard for Australians to suggest such things, when we just approved ADANI.!!!!!!

Yes, but there are more interpretations of that kind of stuff: such as, we are already on 'the' so called path... and that's just one! :jump

A more than interesting complication to a complex equation I dare say: IS THIS COMMON KNOWLEDGE?

(I dare say not, although I'm just ignorant of said fact: thanks for enlightening me Mr Beerest Guy!)

:bike :bike :beer

((Never heard the planting trees on ridges one either, lol... cool: we need to start teaching the kids this stuff like pronto!))

we..?
people and governments who want to stop wholesale destruction of irreplaceable environments, like the Amazon, or the Sumatran jungle. Or the Daintree. !! For just a few examples.

people like me who want to maintain and protect local bio-diversity.

As long as it is someone else's problem, we'll do nothing much.

Lol, I'm talking about the curious use of the word 'we' in fake news and you turn around and attack 'me' for an ever more curious reason!

Don't you like other people taking part in a conversation? :roll :roll :roll :roll :roll :roll
