They're called trees.

If global warming were about reducing carbon dioxide, we would be planting them in every available square inch of open ground.

We could but global warming makes even that pretty difficult. Trees don't fare so well in droughts or extreme heat.

Though I suppose there's still plenty of areas that are viable and some that were previously too cold becoming moderate.

But trees are also not super great for carbon capture. At night they exhale CO2 as we do and they don't absorb a lot. Even if we did cover every practical inch with them it would still take so long to capture it all that the worst of climate change would have long happened.
