The Only Technology That Works at Scale

Everyone wants to talk about carbon capture. Startups raising hundreds of millions of dollars to build machines that suck CO2 out of the air. Direct air capture. It sounds like the future.

According to Oxford’s Stranded Assets Research Group, the only technology currently available that can remove carbon from the atmosphere at scale is planting trees.

That’s it. Forests. The technology we’ve had for millions of years.

What We Already Know How to Do

I’m not saying we shouldn’t develop new carbon capture technologies. We should. But while we’re waiting for those to mature, we have a working solution sitting right in front of us, and we’re not using it nearly enough.

Natural climate solutions include reforestation, sustainable land management, wetland restoration, and agricultural practices that increase soil carbon. These aren’t sexy. They don’t involve venture capital or breakthrough technologies. They’re just… doing things we already know how to do, better and at larger scale.

Six Generations of Knowledge

I met a family of foresters who have been managing forests for six generations. Six generations. They understand things about forest health that scientists are only now documenting. The knowledge is there. The workforce exists. The question is whether we’re going to fund it properly.

Forestry for climate is complicated, though. You can’t just plant trees anywhere. The intersection between forest expansion and community fire risk is real and tense. People who live near forests don’t want more fuel for fires. People who want to sequester carbon want more trees. These groups end up fighting each other when they should be finding common ground.

I’ve met advocates who work specifically on this intersection. Bringing together foresters, fire departments, community groups, and climate organizations. The work is slow and frustrating and necessary.

Beyond Trees

Sequestration also includes less obvious approaches. Materials scientists working on cement that stores carbon instead of releasing it. Microbiologists studying how soil captures and holds CO2. Agricultural researchers testing grazing practices that increase soil carbon. Methane capture from landfills and farms.

The common thread is that we’re not creating new carbon. We’re dealing with carbon that already exists, either by preventing it from being released or by pulling it back out of the atmosphere.

The Unglamorous Side

This is the unglamorous side of climate work. Nobody makes the cover of magazines for improved grazing practices. Wetland restoration doesn’t trend on social media. Foresters don’t get invited to give TED talks.

But the work matters. Natural climate solutions buy us time. They provide breathing room while we construct the clean energy infrastructure we need. Every ton of carbon stored in a forest or in soil is a ton we don’t have to worry about capturing with expensive machines later.

The People We Need

And this work requires people. Foresters, obviously. But also nonprofit workers who secure funding. Policy analysts who design programs. Researchers who measure and verify that carbon is actually being stored. Community organizers who build coalitions. Scientists who study soil microbiology and forest ecology.

If you care about climate and you like working outdoors, sequestration might be your field. If you care about climate and you like the idea of six-generation family businesses, forestry might be your path. If you care about climate and you want to work on solutions that actually exist today, not ten years from now, natural climate solutions are waiting for you.

The technology that works at scale is already here. We just need more people to work on it.
