Massive Forest Restoration Could Greatly Slow Global Warming
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.
- Time to start using https://www.ecosia.o… ?Nairn
- stop deforestation, for onedrgs
- I think in the future, every adult human should be obligated, by law, to plant at least one tree in their lives. Like some grand social conditioning.Nairn
- Agreed. Or one for the death of each family member. Like part of a funeral service to plant a tree over the grave.monospaced
- "A man must build a house, plant a tree and father a son" Talmuddrgs
- make every day arbor dayimbecile
- that's what became the 'save the rainforests' initiative.uan
- but if we plant too many trees and we see a decrease in carbon co2 we could get cold. But our perceptions of co2 data which is on a decent scaledeathboy
- of what like 650,000 years... is a reasonable entry point, but considering we also calculate the age of the earth at 4.5 billion yrs. we have to always questiondeathboy
- wether are data is broad enough, 650K (pretty broad but at what scale?) and even at that scale we see natural co2 level outside humans rise and fall.deathboy
- Which makes absolute sense. What causes our seasonal changes from plants growing and dying and winter coming?deathboy
- Tilt. Something we cant change. Now how about orbit + tilt? Plus source of energy and output? Can we even calculate it?deathboy
- basically i wouldn't try to go on a china beat back the desert by planting trees kick. but net gain as trying to equal it out inst a bad ideadeathboy
- but all at what cost?deathboy
- There’s no conceivable environmental or any other problem with planting more trees. At all.monospaced
- there is if you look at cost and effect mono. like suggesting no amount of money washed down the drain is wasted...deathboy
- but please if you want to fake you know what im talking about explain the benefits of such labordeathboy
- what has chinas cost been, the social effects of such programs, waste, or even increased carbon footprint?deathboy
- those are real effects outside a larger seasonal unchangeable reality that effects life as we know it.deathboy
- If there's a problem, what is it (looking at the cost and effect)? Planting trees decreases carbon footprints. social effects are only positive.monospaced
- Planting a tree is almost free, and weather does most of the work from there. The only cost would be watering it, at most.monospaced
- At the rate of deforestation, planting trees is a way to curb the negative effects that has on the planet.monospaced
- So I conclude — AGAIN — there is no conceivable negative impact of planting more trees. Unless you're a dick and don't like clean air or shade.monospaced
- There is literally NO SUCH THING as planting too many trees, as you have implied. No waste of money, no waste of labor.monospaced
- haha planting a tree has more cost than watering... jeezus lol... guessing someone hasn't even landscaped a backyarddeathboy
- as far as the "too many" trees that is a natural cycle outside our lifetime. Has nothing to do with us planting trees. a joke that you misseddeathboy
- china has spent well over 100 billion in forestation efforts that are not practical and have resulted in a huge waste of funds. im not about central planningdeathboy
- but imagine if you were a planner how you could use those funds in better way. really just a prime example of poor central planning though since that moneydeathboy
- would have a much better chance of helping society in free hands.deathboy
- as far as planting trees outside the china example. i think lumber trade should do it for future investment. but how about ppl in vegas? running non nativedeathboy
- water heavy plants in drought type climates? is that good? Whats the larger costs to agriculture and food. The central planned argument is always funny in howdeathboy
- such small thoughts never worked out. They check out after the dopamine rush of a "good deed" and never look backdeathboy
- "china has spent well over 100 billion in forestation efforts that are not practical and have resulted in a huge waste of funds."
Citation, please?Nairn - imho one of China's next big exports will be 'environmental rejuvenation tech'. Thye've made huge strides reclaiming deserts and aforestation.Nairn
- They've had to, because historical national policies destroyed huge tracts of their environment. Fixing this, no matter how costly, will always be profitable.Nairn
- As for your assertions about water waste, that's bullshit too. Rain over land interiors mostly comes from natural particulate emissions from trees.Nairn
- Global warming means more water in the atmosphere. More trees means more water over land. It's an entirely virtuous cycle.Nairn
- nairn https://royalsociety…deathboy
- think i read it in the economist though. more about the waste and effects of money spent down the soclal pipeline has largely been a waste with no good resultsdeathboy
- "Global warming means more water in the atmosphere. More trees means more water over land. It's an entirely virtuous cycle." huh?deathboy
- by this you are asserting global warming is good and the more we have the better? as far as water usage mention it is focused on man usage not natural particuladeathboy
- the trees china are planting don;t get natural water. nor vegas landscapes (why a lot art artificial turf) but the focus was more directed at mans controldeathboy
- and waste in thinking it can control or know better. especially politcians with little no background chasing votesdeathboy
- "because historical national policies destroyed huge tracts of their environment. Fixing this, no matter how costly, will always be profitable"deathboy
- how so? example? profitable on politician public dime or by peer free trade?deathboy
- planting a tree isn't a big cost beyond water, not at all ... and yes, not only have I landscaped a yard, I do so in the one I fucking OWN and plant trees inmonospaced
- once again, there is NO CONCIEVABLE negative impact to [planting more trees, not economically, environmentally ,socially, or any other way imaginable.monospaced
- Private citizens planting trees puts NO COST AT ALL on a society, the government or regulatory bodies. And your argument about a dry desert is irrelevantmonospaced
- because nobody said or even implied it would work in all climatesmonospaced
- If people planted more trees, those would add to the planet's ecosystem in a positive way, offsetting rapid deforestation ... so it's only a good thingmonospaced
- so yeah, man CAN and SHOULD plant more trees, FOR the benefit of the environment itself, because it is real and measurablemonospaced
- well mono I'm totally fine with private enterprise planting trees and absorbing costs associated with them. However private vs public is quite a differencedeathboy
- i never said that was a bad thing. Just stating how public policy following such thinking creates waste. and pointing out cycles. https://phys.org/new…deathboy
- Outside man popular theory is warming periods produce more vegetation but peak in pulling out too much co2 causing coolingdeathboy
