To get back to healthy levels, we would have to cut our emissions by 98 percent.
“Could you imagine living on 2 percent of your annual income?” says David Battisti, an atmospheric scientist at the University of Washington. “That’s the problem: People can’t envision how you’d actually get this done.”
1. Fake a volcanic eruption.
When particularly explosive volcanoes erupt, they blast ash and sulfuric acid droplets into the atmosphere, which then morph into tiny reflectors that shield Earth from the sun. The result of this natural cycle is a global cooling effect.
2. Make clouds brighter.
Clouds keep things cool by reflecting the sun’s rays away from Earth. The whiter the cloud, the better it is at reflecting the sun. By seeding certain clouds with whitening materials — basically tiny particles of saltwater taken from the ocean below – we can transform them into natural sunshields.
3. Fling a giant sunshield into space.
You know those accordion-like sunshades made for car windows to keep the interior cool during summer? Scientists have proposed using that same principle to cool Earth. This technique would launch an enormous set of particle-based reflectors into space, positioning them between the sun and Earth to act as a giant parasol.
4. Scrub the air of CO2.
The goal here is to separate CO2 molecules from the air by passing it through chemical filters of a sort, which absorb CO2. This technique actually makes a lot of sense if you’re trying to filter carbon dioxide from, say, the smoke stack of a coal plant before it gets released into the atmosphere. If you try grabbing air out of your backyard, however, things get tougher.
5. Enrich the ocean with iron.
Studies have shown that dumping iron dust into the ocean encourages the growth of blooms of phytoplankton — microscopic drifting plant life — that absorb atmospheric CO2 from the ocean.

Julia: YOU ARE AN IDIOT!
I’m just glad that back in the seventies they didn’t spread coal dust over the arctic ice as the “experts” suggested in order to stop global cooling.
First, mankind is responsible for only a small fraction of the CO2 that goes into the atmosphere each year. Even if mankind completely eliminated our CO2 emissions. (both theoretically and practically impossible) we wouldn't make a dent in worldwide CO2 levels.
Second, every time man has tried to "manage" nature we have screwed it up. At least for the first attempt or two, some things we eventually got right, or not completely wrong. Given our track record, do we really want to try something on a global scale? It's one thing to screw up a park, or a lake, or a national forest. It's whole 'nuther ball game to screw up the entire ecosystem.
#1 solution to global warming: stop funding bad science.
It would go away tomorrow.
It’s amazing that someone would write an article like this and not suggest going nuclear for baseload electrical generation and to some mix of fuel cells, biofuels, and electrics for transportation fuels. If one is serious about decarbonizing, the alternatives are there.
“Healthy levels”?
There’s nothing unhealthy at all about CO2 (which I presume is meant) at *any* imaginable atmospheric concentration.
How to get rid of global warming? Blow up the phony computer models that are the source of this fraud.
Or, we could just allow the Sun’s fall-off of magnetic activity continue, which will precipitate an obvious cooling within the next ten years.
We plant trees, and that is “filtering C02 in our back yard”.
I remember the plankton concept, the problem there is being able to reverse it when we realize that global cooling is the real issue, that C02 levels need to be higher, and we start killing off forests because we drained them of their “oxygen”.
