The particulate pollution that makes city air unhealthy is a totally different issue from carbon pollution and climate change.

  Not really. Car exhaust contributes to both. Reducing car exhaust will reduce particulate pollution and CO2.

    Depends on how you solve it: if you solve it by replacing all diesel engines with petrol ones, you're reducing particulate pollution but increasing CO2 emissions.

  Burning less, eg in engines and heating stoves, would very much help both.

    Those are things that should happen anyway. But no joke the world is not in a good place with how things are presently regarding climate change. Two parts of carbon pollution are difficult. 1. It's a diffuse source pollution problem. You can look a coal fire plant, and yes these are great contributers but so are cows and just general agriculture. Emissions come from everywhere! 2. dealing with gaseous carbon pollution is also tricky because its up high and CO2 is reasonably stable. If we are going to try and filter air from the atmosphere we are probably going to have to either look at biological sequestration solutions ie. algae etc or energy expensive options to break down the carbon. And conservation of mass being what it is we are going to end up with a lot of waste to store. And that article talks about 8 million pounds....oh well.
