Water shortages could derail UK’s net zero plans, study finds | Tensions grow after research in England finds there may not be enough water for planned carbon capture and hydrogen projects

Yes, but they don't scale to anything like the amount of CO2 people are adding to the atmosphere by burning fossil fuels. In practice, this means having to phase out fossil fuels faster

Trees aren't carbon capture, no plants are. They rot and decay releasing the carbon they supposedly captured.

Any carbon we capture has to be removed from the carbon cycle some how. I'm not sure you can use the carbon cycle to separate carbon from that cycle. You could grow the trees, then kiln them of all bacteria, then bury that sterilised mass in a sterile hole. But, first prove you didn't just create more carbon than you captured.

I am however, completely uneducated, the above is a carbon capture for infants. Listen to anyone more versed in the subject than I.
