As an antidote to global climate change, scientists are discussing geoengineering: “Major technological steps would be taken to alter the atmosphere to cool off Earth faster. … ‘Geoengineering is in fact untested and dangerous,’ says James Fleming
of Colby College in Maine. ‘We don’t understand it, we can’t test it on
smaller than planetary scales, and we don’t have the political capital,
wisdom, or will to govern it.'”
