Adaptation is key to any solution, but there is a wide spectrum between "prevention only" and "adaptation only." There's no reason not to have both, and they complement each other. And, if nothing else, adaptation has to be funded somehow, and most modern solutions aimed at prevention generate revenue. Some or all of that revenue can be used to fund adaptation efforts. One issue with adaptation is that the people being asked to adapt aren't the same as the people being asked to prevent. It's all fine and good for the USA to say, it's most economically efficient to adapt, because prevention is expensive! But you don't see the USA dedicating a large portion of that profit stream enabled by their externalities to fund adaptation efforts in Bangladesh.
