Not an expert in this... at 103 metric tons of CO2 per acre per year, how many acres of this do we need to plan to make an impact? Look like according to this random Medium blog, we should aim to remove 10B metrics tons every year? So that's 970MM acres? https://medium.com/@friedmann2/going-negative-time-to-suck-it-up-339c5f8a5608 https://medium.com/@friedmann2/going-negative-time-to-suck-i...

That's like 6x the size of Texas. Can probably pull that off if everyone in the world pitches in. Not sure what other effects like invasiveness of the species factor in.

  > The Empress Splendor tree belongs to the genus Paulownia. There are many different species of Paulownia and only one is classified as invasive, the Paulownia tomentosa (http://www.invasivespeciesinfo.gov/plants/printree.shtml http://www.invasivespeciesinfo.gov/plants/printree.shtml). We do not use this variety, choosing instead non-invasive species such as the Paulownia fortuneii.

So like 2% of the worlds acreage...

For people like me who don't have a good mental image of the size of 970 million acres, I did the math and that is just over half of the land in the continental United States.

Carbon and CO2 "emissions" numbers are different "Carbon" is 10B "CO2" is 40B This article says Carbon in the headline but CO2 in the body From the body of the article: > While each acre of most tree species can capture and store 1.1 to 9.5 metric tons of carbon dioxide a year, an acre of empress trees can absorb 103. 40 billion / 103 = 388 Million acres of Empress Trees China is around 2 billion acres in size 22% of China is covered by forests 22% of 2 billion is 440M In theory China alone can solve this problem by replacing the indigenous trees with these trees. Bad idea though for obvious reasons. In practice if every compatible country just got rid of some sub-optimal tree and replaced it with this tree, it could probably work. If we gathered up the annual amount of money spent on "solving" Climate Change - one example that comes to mind is the recent Google summit where all the B-tier Celebrities went to in Yachts and Private Jets. What if we took all the money that these kinds of events cost and devote it to this single exercise. I'm pretty sure it could be done. All it would take is some governments to say OK. They can get paid for it by the other countries too as a one-off payment.
