Cooling down the planet




Engineers start testing methods to cool down the planet. Among those methods is the one published by David Mitchell and others in 2009 to inject Bismuth(III) iodide into cirrus clouds. This will yield larger ice crystals in the clouds and thus thinner clouds which at the end will increase the amount of energy reflected back from the planets surface into space.

160 tons of that powder would have to be deployed per year to achieve a decline of average world wide temperature of 1.4 degree Celsius.

Hopefully the engineers are also working on solutions for drought. Like there are acute water shortages that have become chronic now and predictions are it may even get worse than it is.

It's neat that engineers are working towards fixing the effects of climate change, but unless we work towards fixing the root they efforts will be vain.
