Capturing carbon is really amazingly simple: plant trees.

Unfortunately planting trees doesn't get venture capitalists interested.

[-] Narrrz@kbin.social 6 points 1 year ago

my understanding is that tree planting isn't considered a magical solution because all that vegetable matter ultimately dies and its sequestered carbon is released by the creatures or microbes that break it down for energy and nutrients.

You can't plant old growth forests.

A huge amount of the carbon sequestration done by trees happens well below the ground and takes hundreds or even thousands of years to get effective. If you cut down an acre of trees, you'll have to plant many acres to get the same effect in any kind of human timescale, and that just won't and likely can't happen. That acre was cleared for a reason and it's unlikely just because an identical acre without trees somewhere else was in the wrong place.

Also worth pointing out that carbon capture and carbon removal/air capture are different things. Carbon capture happens at the smokestack. I know it's confusing terminology, but that's what's being discussed in this article and that is what the term means in industry use.

Thank you. Im not who you were replying to but I was confusing the terminology.

We have to plant trees constantly, and store the logs and leafy material deep underground

Then we use the wood.

Wood for construction locks up the carbon for decades to centuries.

Leaves become animal fodder and from there become fertilizer.

The more we replace disposable plastic with disposable paper the fewer microplastics we add to the environment.

If wood ends up in a landfill, its carbon gets locked underground for centuries. An anoxic landfill, and it could stay down there until it turns into oil. Dump it in the ocean and it sinks down among the shipwrecks and becomes fish habitat. And the worst poison wood leaches into the environment is the stuff black walnut uses to kill other plants.

Compared to everything else we make crap out of, wood is an ecological miracle.

And if all else fails wood for heat and power is literally carbon neutral.

Climate - truthful information about climate, related activism and politics.

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: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
