Any comments on this?

Well, some scientists blame this on the burning of natural gas and oil, but looking closely at the data the picture is far more equivocal.
Blaming the 0.6 - 0.8 deg C rise in global temperatures on a rock that exploded high above the Siberian tundra in 1908 sounds as much junk science as most of the global warming/climate change hysteria. A correlation is not a cause, and a theory needs evidence to be anything but speculation.
It's an interesting idea, but if there is significant dust in the upper atmosphere then we would be seeing very red sunsets.
