Why might geoengineering proposals pose complex political, financial, and technological challenges??
What will be the ideal response?
ANSWER: Answers may vary, but should address the following:
Geoengineering proposals may have unforeseen or unwanted consequences. Injecting the stratosphere with sulfate particles, for example, might alter the temperature of the upper atmosphere and affect the fragile ozone layer. Carrying out large-scale geoengineering would be quite expensive, and it would also call for global agreement on techniques and procedures, since the results could affect the entire planet. As we have seen with the Kyoto Protocol, such global agreement can be very difficult to obtain. In short, the science of geoengineering is intriguing, but it poses complex political, financial, and technological challenges.
