If you planted a tree every second, it would take you 31 thousand ish years to plant them all. That said, if you had 100k people planting them itd take under a year. Can a machine plant 1 tree per second? Id be interested to learn that

We could do a lot better than planting 1 per second. How about planting 900,000 trees per day via aerial bombardment?

So the count of how many trees there are now was off by an order of magnitude. And we are supposed to give credence to an estimate of how many there were 10,000 years ago? What makes you think that's any more accurate? This kind of sloppy science is ruining people's confidence in science. I know it's supposed to be an iterative process, always getting better, but there should be some self awareness built in that earl…

I'm not able to read the actual research paper, but the article refers to the "United Nations estimates of global forests." I'd assume they used the model they developed for forests and applied it to this estimate to get a number of trees.

Interestingly, planting 1 trillion trees all at once would decrease the albedo of the earth ( https://en.wikipedia.org/wiki/Albedo ), increasing warming in the short term. I wonder how long the trees would have to exist before the scrubbing effect on carbon dioxide would outweigh the albedo change?

Geez, albedo is a topic I didn't know existed until just now, but which is clearly a complex enough topic for hundreds of people to spend their entire lives studying it. Super cool.

In Southern India Project Green Hands ( https://en.m.wikipedia.org/wiki/Project_GreenHands ) has focused on planting trees by hand. On 17th October 2007 they started a tree planting marathon that resulted in 852,587 saplings being planted in 6284 locations across 27 districts in Tamil Nadu by over 256,289 volunteers in just three days - fairly modest average per person but still enough to set a world record.

Planting 1 trillion trees by 2020 would take each of us 7.3 billion planting around 140 trees over the next 4 years.

Look here: https://www.google.com.au/maps/@-33.0362291,118.4896355,5465... Can you figure out where there used to be trees ? That's now wheat farms mostly. Due to the tree removal salination has ruined 2 million hectares of what is now essential wasteland. https://en.wikipedia.org/wiki/Salinity_in_Australia

Wow, the way the farms are perfectly cut around the protected regions... I thought that was just tiling in GMaps. That's horrifying.

Earlier quoted context omitted.

You're describing one form of carbon offsets. A cap & trade system is pretty much what you're suggesting, depending on the specific implementation of a cap&trade system. https://en.wikipedia.org/wiki/Carbon_offset#Land_use.2C_land...

I did not realize cap and trade systems were backed by actual carbon storage. That makes more sense then. Thanks for the link.

they don't have to be.. but most cap and trade proposals include carbon offsets... so a polluter can complete an offset project OR purchase credits to pollute more.

Depends on what the trees are shading? They couldn't be much worse than concrete I imagine...

https://en.wikipedia.org/wiki/Albedo#Terrestrial_albedo Albedo of a conifer forest is 0.08 to 0.15, albedo of new concrete is 0.55. The climate change effects of reforestation are addressed later on in the same article: https://en.wikipedia.org/wiki/Albedo#Trees

Of Asphalt it's only 0.4 - 0.12 though (from your link)

That's an interesting thought. It immediately made me think of some fast moving contraption that buried seeds into the ground. Obvious difficulties would be navigating, and being small while being able to force something into the ground.

I can't tell if you're joking or not. The answer is a f'n bird.

Not quite 1/second, but imagine having a bunch of these running around in your neighbourhood.
