The article discusses how current efforts to reduce global emissions are not enough to meet the Paris Agreement goals, prompting exploration of methods to cool the Earth in the long run. The researchers show that even if temperatures overshoot, lowering global temperatures afterwards is crucial to lessen future climate risks like rising sea levels and melting ice. It's not guaranteed that using carbon removal tech to cool the planet will work, so having a lot of it ready could help prevent major warming feedbacks. Trying to cool the Earth later isn't enough; we still need to cut emissions now to avoid serious climate issues when temperatures peak.
