Geo engineering

Environmental scientist David Keith proposes a cheap, effective, shocking means to address climate change: What if we injected a huge cloud of ash into the atmosphere to deflect sunlight and heat?



Shocking idea! But it makes definite sense to have global agreement over next steps of tackling climate change.

Geo engineering makes me think.

• Makes me realize that the global climate could change dramatically over a short period of time. I knew that it was possible and it has happened many times in the past, eg the extinction of the dinosaurs, volcanoes, etc; but when someone asks you to make a choice of whether that is the future you want for your own planet ... hmm ... not so sure, difficult one.
• Such research, does however, gives us the ability to influence the climate of planets we might inhabit in the future. In the future, you won't need to buy the "I am rich" app to prove that you are rich, all you would need is a custom built planet ;)
