Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

That's what everybody said about solar / renewables in its infancy. We know we're going to need the technology, far better to start developing it now than when it's too late.
yeh this is a really promising technology and it's not as far as most people seem to think from being widely adoptable, there are some great projects underway
basically you grow a load of plants (generally the excess biomass from crops and maintained spaces) and burn them (in this case through a gasification process that releases hydrogen also) the carbon which is released is then captured for storage or use, this can be especially useful when burning plants that have grown on toxic ground or polluted rivers as a way of absorbing all the bad stuff which is then trapped forever and returned to an old coalmine along with all the carbon that originally came from there.
another interesting project that just got funding is DRIVE;
using the captured carbon to make useful materials like building aggregates makes it far more likely systems will get adopted, especially if they get to a price point where they're creating profitable items This is something a lot of people are working on
Another really cool use of captured carbon has recently passed a loads of tests from the US Air Force who've worked with a company called Twelve on a project to create a viable jet fuel from CO2,
the test facility they're currently building isn't going to produce much but it's a huge first step on the way to industrialisation of the technology,
that's only about 0.00007% of the Jet Fuel used per year, but if they refine the system and make one which can be built at any airport using power from onsite renewables then it's likely we'd see a very rapid adoption.
I don’t think that’s true, can you back up your claim?
I support research and development of the technology, because it’s something which could be useful in the future. But this article is about building carbon capture facilities today, which is a big waste of money.
It's survived till today as a conservative talking point. How solar can't pay off its own manufacturing costs, etc etc. None of it's true, but that's where it started.
R&D does not happen solely in the lab. At some point, you need concrete, full scale examples to work with on ironing out the kinks and figuring out where theory doesn't apply in reality.
We're not building a thousand of these plants. This is the early PoC example that we need to progress the technology.
Sure, I’m happy to support building large scale experimental establishments to test the theories, but that’s not what this is at all. This is a commercial installation in Africa, of all places. Why would the European research teams build a research facility so far away? That doesn’t make sense.
What's the difference between a large scale experimental establishment, and a first of its kind commercial experimental establishment?
As for location, presumably cheap land, power, lack of NIMBYs. Maybe tax incentives.
It’s not the first of its kind though. It’s just the first in Africa. There are already a bunch of these in Europe and America.
If the researchers are in Europe then it doesn’t work for the plant to be in Africa. I don’t know why you’re arguing such an obviously wrong position lol
Yeah scratch the first of its kind, wasn't thinking when I wrote that. Nevertheless, my point stands. For the technology to grow and develop we need PoCs to be constructed. Valuable data can be obtained from operating the PoCs that we wouldn't otherwise get.
In this age where everything is networked and teams can be distributed worldwide, what in the world does it matter if the plant is in Africa? If anything, it would be encouraging knowledge transfer and dissemination.
In most online discussions, that's exactly how the other person feels about you. We generally keep it civil by not saying it out loud, though.
More than 10 years ago solar and wind were talked about very diffrently. They required subsidies to operate and weren't cost effective. We nursed the new technology to commertial viability and everyone forgot about that part
That's my though, do the r&d now and full scale deploy when we have more renewabel energy
