new york is small on the map but imagine all the material we have blown and will blow into our atmosphere. a lot of the organic material from carbon and other ages.

for example the current estimations say that there still are 800 billion tons of coal available. according to my rough calculation this would be about 3 times the area of germany if you made a 1m thick layer. i could imagine that burning this has some global effect?

i haven't looked up how much coal we already have burned since the beginning of industrialization or how the amount of oil compares to that.
