Maclean’s has featured an article last week on geoengineering – http://www2.macleans.ca/2009/04/22/plan-b-for-global-warming/
The article focused on work of David Keith from UofC. His main article on geoengineering – “Geoengineering the climate: History and prospect” can be found here (in full text PDF for UBC folks)
A quick search in Web of Science database shows that every year there are twice as many article on this topic than a previous year…
Here are some folks in UBC Applied Sciences that work in this area
