Polar vortex the Sky is falling

Thanks for the clarification ...

The abundance of paving certainly doesn't help the temperature, but we could go on there are just many factors involved.

Im not sure if Tunguska would be classified as a climatic or weather event, though like volcanos it likely had a long-lasting effect on the weather

Actually I think paving helps: the lime in concrete sucks CO2 out of the air. I think it is something like calcium hydroxide sucks in carbon dioxide and calcium carbonate is formed, a solid on the ground, no longer part of the atmosphere. But I’m not a chemist so don’t quote me on that exact chemical reaction.

However a coal seam fire would appear to suck less weight in O2 out of the air than the weight it adds in CO2.

The Tunguska blast is not sufficiently explained by any prestigious scientific publication. But I am quite convinced it was due to the serious climate risk of excessive coal burning, from the massive Tunguska coal mining operation, going on directly underneath the blast. That is no spurious correlation.
