Lately we are used to reading and listening to different environmental ideas of tackling the effects of global warming by reversing the effects of climate change. Geo-engineering measures are now being considered more seriously and getting more and more support.
Recently the IPCC has released a special report on renewable energy and climate change. And now it is launching a special meeting on this particular issue of geo-engineering which is taking place in Lima (Peru) next week where scientists and experts will debate this issue.
Ideas such as blasting sulphate aerosols into the stratosphere to reflect sunlight into space, depositing massive quantities of iron filings into the oceans and bio-engineering crops to be a lighter colour to reflect sunlight to suppressing cirrus clouds will be some of the topics discussed.
The future of geo-engineering solutions and its applications, risks, regulation, and its consequences require more detailed research.
But, are technical solutions the only way?
