From Chris Dinsdale, Barrie, Ontario, Canada
As the world continues to react at a snail’s pace to the threat of climate change, we need to at least start to experiment with geoengineering. The poles are nearing a runaway feedback loop that will forever change the Arctic and, in turn, world weather patterns. Does anyone truly believe our current governments can cut emissions enough to stop this disaster(18 January, p 32)?
No one wants geoengineering as a permanent solution, but it should at least be considered as a stopgap measure. This world needs our poles to stay frozen.
