I appreciate that science fiction can be fun to read. But, given the sobering reality of abrupt climate change happening today, should we not draw people’s attention to the importance of reducing our CO2 emissions quickly? Should we not focus on the only technologies that have a realistic chance of cooling the planet today (solar radiation management and carbon sequestration technology)?
