Adding to the climate’s problems

If geoengineering becomes a reality (Greg Foyster, “Particles of faith”, March 18-24) and indeed works to cool the planet, what incentive would there be then to reduce our carbon emissions? It could be seen as business as usual, to keep ramping up our sulphate spraying in the upper atmosphere in an escalating cycle of eventual destruction. The answer to humaninduced climate change can never be to increase our environmental footprint, only to decrease it.
