Creating a 'sulphur screen' (BBC) {HOLY CRAP -- DUMPING sulfur into air}

[eppur_se_muova]

Launching rockets to create a sulphur screen high in the stratosphere is one way to counter global warming explored in a new BBC documentary, Five Ways To Save The World.

In 1995, Professor Paul Crutzen won the Nobel Prize for helping to explain how the ozone layer is formed and depleted.

Partly as a result of his work, world governments took action and banned the chlorofluorocarbons (CFCs) - chemicals used in fridges and aerosols - that were thinning the ozone's presence over Antarctica.

Now the chemistry professor has a solution to mitigate global warming.

He believes that sulphur particles similar to those erupting from volcanoes could act as a natural cooling device for the planet, by creating a "blanket" that would stop the Sun's rays from reaching the Earth.

OK, I don't really like this idea -- but if we're going to talk about putting something reflective in the air, let's make it something benign. See http://www.democraticunderground.com/discuss/duboard.php?az=show_mesg&forum=115&topic_id=83309&mesg_id=83309

1. I keep saying

that what we need is a good volcanic eruption to offset the CO2 effects.

2. That professor needs to read this thread.

3. On the up side, lots of sulfuric acid in the air we breathe could

drastically mitigate earth's overpopulation problem.................

4. Did these people never see a dead lake killed by acid rain?

[hatrack]

5. And what would this do to slow ocean acidification?

Oh, that's right, it wouldn't do anything.

6. Actually, it might "upgrade" it to fast ocean acidification! nt
