Paul Broady suggests plans to capture carbon from the air are a distraction, and we should focus on deep cuts in emissions. He is half right. We do urgently need to make deep and permanent emissions cuts and to keep cutting until we get as close to zero as we can. But this won’t be enough(Letters, 11 October).
We are already 1.5°C (2.7°F) above pre-industrial temperatures. The latest science shows that we need to get this down to 1°C (1.8°F), and the only way to do this is to remove carbon dioxide from the air. The limitations of current carbon-capture systems aren’t reasons to ignore this option. In fact, we should see these limitations as reasons to invest more in carbon capture R&D.
