  • To roll it out to the levels needed would be far more difficult and expensive that converting our entire way of life to renewables

    The cost of geoengineering solutions has been estimated to be less than $5b/yr, which includes R&D. In other words, this is something that the government of New York City (annual budget: >$100b) could easily do alone without any international support, even in the face of significant opposition.

    In contrast, ending fossil fuel use requires significant international cooperation and is regularly stymied by opposing interests. NYC obviously cannot do it by itself.

    So from a pragmatic perspective, geoengineering is definitely the easiest solution. In fact IMO the lack of progress on emission reduction makes it inevitable, at some point some country will weigh the risks of climate change and take matters into its own hands.
