Curing climate change

One of the proposed technical solutions to climate change is to induce 'cooling' of the Earth by blocking the sun's rays. This idea builds on the volcanic eruption, especially that of Mt. Pinatubo during in 1991. The ozone layer may thin though if this option is pursued. Given this reactionary attempt to delay climate change is feasible, which would you prefer? A cool climate with an ozone hole that is at risk? Read more about it in BBC.
