Just Block Out The Sun, What Could Go Wrong?
Tell Gates to fix Microsoft first
On a more serious note having a conversation about climate engineering seems like a good idea to me. It's when you get around to the implementation phase that we may want to be really cautious.
I have long maintained that the most immediate "climate" threat to humans is short term cooling from volcanic activity. It's my opinion that the reason that warming gets all the attention is political. Powerful people like to control things. It was true thousands of years ago and it's true today. All the ideologies are just excuses for being authoritarian. Does it really matter if it is a Genghis Khan or a Mao? Ford, Carnegie, Kellogg, Rockefeller all had their social engineering experiments.
Seeding the atmosphere? I thought climate change was all about atmospheric pollution, specifically greenhouse gases, that caused the greenhouse effect, not allowing heat to escape thus warming the planet. How soon we forget. We need real science. Not political BS.
