>There are major costs associated with cutting carbon emmissions before we have better technology.
But the technology has been rapidly getting more economical, and in some ways is now actually cheaper than fossil fuels (which also has many negative externalities of its own). And this has been happening only because there has been an enormous investment in renewable energy. The idea that the scientists all on their own will work for decades and come up with fully-ready technologies that then will be put into full production is just not how these things actually work.
