Resumen de A Hacker's Guide to Planet Cooling.

• The article looks at potential geoengineering-based solutions to the problem of global warming caused by the accumulation of greenhouse gases in Earth's atmosphere, expressing support for experiments with such approaches despite criticism from some environmentalists and scientists. It describes geoengineering solutions that attempt to either reduce atmospheric carbon dioxide or block sunlight. Marine biologist Victor Smetacek's experiments with iron fertilization of phytoplankton are cited.
