The front-page article in The Tribune on March 10, Ideas gaining steam to slow climate change, points out a number of geo-engineering schemes currently being talked about to mitigate the effects of global warming. Proposed technologies read like science fiction: reverse power plants, cloud whitening, etc.
Many of these geo-engineering ideas are gaining traction due to the efforts of Bill Gates and the National Academy of Sciences. Considering the lack of political will on the part of many governments to take bold action on reducing greenhouse gasses, it shouldnt be surprising that many untested (and potentially dangerous) climate control technologies are being considered.
While it may prove necessary to utilize some of these technologies in the future, there are a range of good strategies such as a revenue neutral carbon tax, renewables and conservation available for seriously reducing the carbon dioxide emissions in the present. It is imperative that we put pressure on our elected officials to take leadership in implementing these common sense and less costly alternatives for reducing greenhouse emissions. Public impatience with inaction on climate change is growing. The time for action is now.
