SA: The excerpt below is from a paper in Science that unfortunately shows how unlikely it is that the world will meet the Paris Agreement temperatures (2C or less, ideally 1.5C). The conclusion is that we cannot rely on carbon dioxide removal technology during the meaningful time when it would be most needed.
“Carbon dioxide removal (CDR) cannot be relied on to contribute substantially to limiting global warming over the next several decades, which is the timescale relevant for achieving the Paris Agreement temperature goals. Some scenarios compensate for longer timescales until net negative emissions become possible by allowing for an “overshoot” of CO2 and associated global mean temperature that is later compensated by even greater amounts of mitigation and CDR. However, such overshoot scenarios present a substantial additional climate risk, and it is not clear at all why a continued lack of progress in the present should be followed by much greater progress in the future. Taken together, these considerations make the Paris temperature goals increasingly implausible.”
