As the carbon dioxide in the air hits 400 parts per million for the first time in human history, some are arguing that the best way to address climate change is to use the controversial practice of geoengineering — the deliberate altering of the Earth’s ecological and climate systems to counter the effects of global warming. Democracy Now! speaks with Clive Hamilton, professor of public ethics at Charles Sturt University in Canberra Australia, about the pros and cons of geoengineering and some proposed projects in his new book, “Earthmasters: The Dawn of the Age of Climate Engineering.” Hamilton points to an example, cautioning, “There is virtually no regulation of geoengineering. And when it comes to sulfate aerosol spraying there is nothing to prevent a government, any government, or even a corporation, or a billionaire with a messiah complex from launching a program of taking control of the Earth’s weather by installing this kind of solar shield. So the absence of governance, the absence of regulation and the exclusion of people particularly from poor and vulnerable countries is a very serious concern.”
