Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.

Rules:

-- PLEASE KEEP POST TITLES INFORMATIVE --

-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --

-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --

-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today . Twitter screenshots still need to be sourced or they will be removed --

-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--

-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--

-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --

-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

Hi! Not a climatologist, but plant scientist/ecologist. Can you elaborate more about why tree planting isn’t enough? A mature forest is carbon neutral, yes. Young saplings will fix atmospheric carbon as they grow, though. I have no idea how many you’d have to plant to make a dent in the runaway atmospheric carbon levels - is that the issue? It would also have to be a careful species choice depending on location, with (I’d imagine) a preference for longer-lived species with persistent wood.

I’m not saying afforestation is the solution, but surely it’s one facet of a comprehensive solution?

Think of it like this:

Let’s pretend the natural, completely free of human influence planet has 10 carbon units in the carbon cycle. If something were to burn down trees it does upset the natural balance of atmospheric carbon, but you are simply changing where the carbon is, not the total amount. This might upset the climate temporarily, but the total number of carbon units in circulation is still 10.

Now let’s add human activity to the equation. We are taking carbon that was in long term storage (oil, coal, natural gas) and adding it to the 10 carbon units we had before. So now instead of a total of 10 carbon units either in trees, the atmosphere, etc, we have a total of 13. Ignoring the fact that we can’t just plant or expect lush forests everywhere, the maximum impact they could potentially have us not actually all that great.

If we wanted to biologically sequester carbon, we would have better luck using fertilizers directly into the oceans to force algal blooms which then die and sink. Of course, this has other consequences unfortunately
