A wave of startups say seaweed is a multi-pronged solution to climate change: It can absorb carbon, curb the effects of cattle's methane burps, and feed biofuels—not to mention the world.

Spreading crushed stone across farm fields could inexpensively pull CO2 from the air while also increasing yields. But it would require a mountain of mining

Carbon-removal technology is still in its nascent stages, but it could be crucial to avoiding the worst effects of climate change.

Two centuries of burning fossil fuels has put more carbon dioxide, a powerful greenhouse gas, into the atmosphere than nature can remove. As that CO2 builds up, it traps excess heat ...

From "MooLoos" to painting mountains, these silly scientific suggestions could actually help with climate change.

Tech firms, oil companies and the U.S. government are investing billions of dollars in carbon capture technology to suck greenhouse gases out of the atmosphere. Can it save the warming world?

Berkeley chemists have created a reusable material that pulls carbon dioxide from the air and holds onto it until it can be stored.

The U.S. government is planning to crack down on power plants' greenhouse gas emissions, and, as a result, a lot of money is about to pour into technology that can capture carbon dioxide from smokestacks and lock it away.

From using mechanical trees to dimming the sun, researchers are getting creative to fight climate change.

A Harvard-affiliated Canadian company is making a liquid fuel that is carbon neutral, and they hope the economics will be in their favor.

The direct air capture industry is still in early stages, but government and corporate interests are pushing it as part of a solution to the climate crisis, despite cost and criticism.
