They will never have enough information - but will that stop them? This is just the public side to get everyone used to what they are already doing and is starting to come out.
The unknown risks of “geoengineering” – in this case, tweaking Earth’s climate by dimming the skies – left many uneasy.
"If we could experiment with the atmosphere and literally play God, it’s very tempting to a scientist," said Kenyan earth scientist Richard Odingo. "But I worry."
Arrayed against that worry is the worry that global warming – in 20 years? 50 years? – may abruptly upend the world we know, by melting much of Greenland into the sea, by shifting India’s life-giving monsoon, by killing off marine life.
If climate engineering research isn’t done now, climatologists say, the world will face grim choices in an emergency. “If we don’t understand the implications and we reach a crisis point and deploy geoengineering with only a modicum of information, we really will be playing Russian roulette,” said Steven Hamburg, a U.S. Environmental Defense Fund scientist.
