A Concept in Geoengineering: Stop Burning the Amazon Rainforest
| November 7, 2010 | Posted by Craig Shields under Renewables - Science |
We’re starting to hear more about geoengineering, i.e., manipulating the planet’s climate as to undo the effects of greenhouse gases. No major actions have been taken to date, and the subject is so intensely debated that it is extremely unlikely that anything will happen soon; there are profound questions that need to be resolved in many different disciplines in politics, science, and ethics, for instance:
What agencies would be responsible? Who should control the Earth’s thermostat?
What exactly are the goals?
What is the best combination of methods to accomplish the goals?
Who will pay the costs?
How can we ensure that the cure’s not worse than the disease, i.e., that the risk of unintended consequences is justified? Read More
Geoengineering 101

Some of the recent conversations here have touched on the idea of geoengineering, i.e., taking pro-active steps to mitigate the greenhouse gas problem more aggressively than simply cutting emissions. This is a hot topic, if I may use the pun, in many of the current conferences on sustainability – albeit a fiercely controversial one.
Rightfully, the concept of shooting particles into the mesosphere (the layer above the stratosphere) to shield the Earth from incident sunlight that is melting the polar icecaps is quite contentious, yet I personally recommend that everyone have at least a surface level of understanding of the topic. To that end, here’s one of the magnificent “Ted Talks” by scientist David Keith, who, in 16 minutes, presents the basics of the subject in a quite accessible way.
