However, other atmospheric scientists argue that the complexity of the climate system means that it is impossible to draw any firm conclusions about the consequences of such a radical intervention in the Earth system. They point out, for example, that the chemistry of the atmosphere is complicated, so turning down the amount of sunlight reaching…
Space mirrors & painted roofs Geoengineering may be defined as deliberate, large-scale intervention in the climate system designed to counter global warming or offset some of its effects. More than 40 schemes have been put forward, with some the subject of intensive research. They are usually divided into two types: methods to remove carbon dioxide…
‘The Ultimate Technofix’: Playing God with the Climate – By Clive Hamilton / CAPPE March 7, 2013: Climate scientists have watched with mounting alarm as carbon dioxide concentrations have increased relentlessly. The anxiety has deepened each year as it has become clearer that the range of emissions paths mapped out by experts in the 1990s…
