In this article for Nature, climate scientist David Ho re-iterates his long-standing argument that while there is no denying “the need to develop CDR (carbon dioxide removal) methods over the longer term”, urgently cutting down emissions is important because currently available CDR methods will not remove enough carbon dioxide to be able to compensate for the levels of emissions.
Ho argues: “We must stop talking about deploying CDR as a solution today, when emissions remain high — as if it somehow replaces radical, immediate emission cuts.”
This is necessary because:
“Developing methods to verify that CDR works is a major challenge. It will be many years before we have the science to tell us which methods work and whether they harm or benefit the environment.”
