Could geo-engineering be the solution to global warming or are some ideas closer to science fiction?

Scientists say current measures like reducing carbon emissions might not be enough to fight global warming, so they are looking at radical new solutions from weather balloons to giant fans that can suck carbon out of the air, geo-technical methods like releasing particles to dim the rays of the sun, and dumping iron into the ocean to grow algae that suck up carbon dioxide - all in the name of reducing climate change.

Professor Miriam Diamond of the Department of Earth Sciences and School of the Environment, says "[fighting] global warming is not about saving the environment. It's about saving us."

Diamond uses examples of extreme weather events related to climate change to illustrate its effects on people. The forest fires in British Columbia displace thousands of people and cause widespread air pollution, which in turn causes adverse health effects. The devastating heatwave in southern Europe has caused a 15% increase in emergency hospital admissions in Italy. "Climate change is about us," she adds.

Professor Diamond says some of the new measures being considered to remove carbon dioxide, a gas that contributes to global warming and extreme weather events, from the environment might prove to be more science fiction than reality.
