With policymakers and political leaders increasingly unable to control global climate change, more scientists are considering the use of other engineering approaches other than control at the source to reduce warming impact. The problem is whatever you do, it will have some impact somewhere and somehow. The impact may be good but it also may be bad. University of Iowa
The U.K.’s Institute of Mechanical Engineers has proposed three geo-engineering schemes officials say could be immediately implemented to slow global warming: building artificial trees that absorb large amounts of carbon dioxide, using algae tubes to pull CO2 from the atmosphere, and painting the roofs of buildings white.
The engineers said that these three ideas, if carried out on a wide scale, could absorb much of the CO2 produced annually in the U.K. and cool temperatures.
The engineers shied away from more ambitious geo-engineering proposals — such as seeding the oceans with iron to encourage the growth of CO2-absorbing plankton — and focused instead on practical solutions that could be carried out soon.
