: its debris lit all the world's forests on fire at once"
the means ?
"a global infrared pulse."
" an intense pulse, estimates are that there were as much as 10kg of debris that fell back through
the Earth's atmosphere for every square meter of the Earth's surface"
". Preliminary calculations suggested that the resulting infrared pulse
would be enough to set every piece of vegetation on the planet ablaze"
. "No non-aquatic vertebrate much larger than a squirrel survived
All the survivors could have plausibly burrowed underground to survive the conflagration."
think of the soot that fire produced eh
black out the sky ?
"To a certain extent, this calculation zooms right past a rather important point: regardless of what, precisely, put the soot there, there was a whole lot of it in the atmosphere"
". So much, in fact, that modern climate models aren't even built with the capacity to model it. "
"However, one attempt has been made to load a model atmosphere with 0.2 percent of the soot expected to have been put into the atmosphere. "
"Even at that level, the global temperatures were predicted to have dropped to ice-age conditions quickly and stayed low for over a decade afterwards."
" Attempts to calculate the impact of the full atmospheric load suggest, at least initially, that no sunlight would have reached the surface of the Earth at all."
