Engineering Our Planet

Engineering Our Planet

  While the international community focuses on emissions and alternative energy, another option has attracted attention. Some experts believe that with geo-engineering, humans can solve environmental challenges by physically modifying the planet. Corporations, engineers, and scientists have started to implement technical solutions, but many are dubious of the inherent risk in manipulating the natural environment.
EARTH MEANDERS - It is being widely suggested that humanity can "geo-engineer" a global solution to climate change; that is, modify the Earth's biosphere at a planetary scale. Many methods are proposed. Most include either reflecting additional solar radiation away from the Earth, or using the ocean to store more carbon. Reactionary geo-engineering proposals emerge largely from a sense of desperation as the world fails to rein in greenhouse gas emissions, and an unwillingness to make necessary societal and personal changes in response to deadly climate change. To some the extreme action of taking the Earth's... See More
THE HARD LOOK - I testified that the oceans will not rise and flood the bay because before that can happen, before the Greenland Ice Sheet can melt, someone is going to employ "geo-engineering" to turn down the global temperature. They will do that by replicating what volcanos do. They will put small reflective particles into the troposphere that will create a sunscreen that will stabilize the global temperature at a level that will prevent melting of the glaciers and thus prevent a rise in ocean level. They will do this because it will be one one-thousandth less expensive than trying to control emission of... See More
BIOPACT - Wednesday, August 15, 2007 Climate change and geoengineering: emulating volcanic eruption too risky Global warming occurs when greenhouse gases, such as carbon dioxide from burning fossil fuels, build up in the atmosphere and alter outgoing longwave radiation. Scientists have proposed different 'geoengineering' options to tackle the problem, in case governments, industry and citizens do not succeed in reducing their greenhouse gas emissions. Some of the proposals include: seeding the oceans with iron to ensure that algae sequester carbon dioxide which would then drop to the bottom of... See More
