This is way over my head, but it sounds promising. Apparently one of the biggest pollutants that has some of the most impact on rising temperatures is… not carbon dioxide… but soot. Not only that, but the technology already exists, and isn’t terribly expensive, to filter most soot from power plants, cars and whatnot.
Not only that, but doing these things would have a fairly quick effect on things, since soot stays in the atmosphere much less longer than carbon dioxide, which stays up there for years and years.
“Soot has such a strong climate effect, but it has a lifetime in the atmosphere of just a few weeks. Carbon dioxide has a lifetime of 30 to 50 years. If you totally stop CO2 emissions today, the Arctic will still be totally melted,” said Stanford University climate scientist Mark Jacobson. If soot pollution is immediately curtailed, “the reductions start to occur pretty much right away. Within months, you’ll start seeing temperature differences.”
Now to get them to put some more work into the science of this, and getting congress on board to work on getting the right filtering technology into cars, power plants and other pollution sources. Hopefully they’ll work faster than the ten years it usually takes to get something like this done.
