I like Bjorn, people just write him off calling him a 'warmist' because he understands the science.
There 'particulate pollution' Smog, and there's CO2 pollution GHG...
The processes that would remove GHGs, would also remove Smog. However the processes that remove Smog don't necessarily remove GHGs pollution.
I'm not surprised that a journo was confused, there not experts in anything.
