Weighing Solar Radiation Management Options

Weighing Solar Radiation Management Options // Published on Jan 29, 2017

To have a fighting chance of arresting abrupt climate change we must deploy Solar Radiation Management Tech to cool our planet and buy us time to remove carbon dioxide from the atmosphere and oceans and slash human emissions. We have no choice. These technologies are not risk-free, but risks must be weighed against the near-certainty of collapse of global food supplies and geopolitical chaos.

    Re the concept of mirrors at the sun-earth lagrange point, solar sails out of micrometer-thin mylar have recently been demonstrated in flight, and the cost of launch is coming down rapidly.

    In the shuttle era it was around $30,000 per kg, the Falcon Heavy partly reusable launcher is at about $3000 per kg, and the proposed Spacex ITS fully reusable launcher would put up 300 tonnes per flight, at as low as $100 per kg.

    I think u better look up once in a while buddy. They have been spraying here in n. Wisconsin for over 20 years. We see 40 +planes daily on same course mostly. U must really be in the dark. What does that do to your climate models??
    How much more nano aluminum can they possably spray??
    Look up pal!! RJ
    Better put the arctic on hold and go educate yourselves on geoengineering already going
    Strong. Deadly, all my forest trees dying

    Guy mcpherson also when asked after his presentation durring question and answer DO YOU THINK GEOENGINEERING WILL HELP? HIS ANSWER WAS NO THEY DONT AND WILL NOT!!
    Be so ignorant on this. It serriously brings your credibility into question.

    I see my comment on Geoengineering isn’t posted. U have my email if u wish to explain.

    I hope all of you psychopaths are brought up on charges for crimes against humanity.
