Quote:

Planting billions of acres of trees in an area the size of the US could be the “most effective climate change solution to date”, researchers say.

A study found there is the potential for an extra 900 million hectares (2.2 billion acres) of tree cover in areas that would naturally support woodland and forests.

As they grow and mature, the trees could absorb and store 205 billion tonnes of carbon, the analysis published in the journal Science suggests.

Seems like one of the most sensible solutions.

We can all agree on this initiative

Yes, it would likely be helpful, esp. in temperate zone where ecosysems regenerate very quickly and many countries are wealthy enough to afford losing arable grounds.

More trees. I approve.

Also important to plant autochthonous trees native to the area to allow regeneration of the ecosystems

I heard this on the radio and thought, WOW, I can support more trees. Like cyberdad says, the trees need to be ones that fit the ecological bandwidth of each area. Some trees can be invasive and disrupt ecosystems in an area to which they are not native.

Generally yes but there are exceptions http://www.bbc.com/future/story/2019050 ... ate-change

Good point Magz.

So the purpose of weeds or hardy fast growing species is to allow primary colonisation of wasteland to allow stabilisation of topsoil. This is useful where you have land cleared for mining, farming or forestry and it turns into a wasteland because the topsoil has been blown away.

Once the weeds are established you can then plant local tree species.

If they turn Australia into one big forest that should take care of things.

I understand that could be hard because it seems warmer times correlate with aridity in Australia. However, maybe skilled management of vegetation could help.
We can probably use the global warming to let new forests grow in subpolar regions, allowing a bit of self-regulation for the process.

Trees are an excellent source of oxygen, since they excrete it.

Planting more trees would certainly enhance the entire world ecosystem.

Yes!I try to plant a few every year to replace the trees I use for firewood.Native species are great, they are usually more pest resistant and don’t need supplemental water once established.Many provide flowers for pollinators and food for wildlife.And they are beautiful.Its a win win for all involved.
One of the most beautiful is the American Fringe tree.It is small enough for yards,the most amazing blooms that smell sweet, lovely fall color and if several are planted there will be berries for the birds.Its also know as Grancy Greybeard.
I think we need more trees in parking lots,they are so hot and barren looking.

slightly off-topic, but somewhat related: I found this thing the other day:

...and now I really want one!

It's possible, even in the city - 46% of Berlin (total 220,400 acres) is green space/forrest and water.
