I was very interested in Mike's suggestions about soot deposition and albedo
amplification. There is also a direct albedo change on the charred ground.
I am unable to quantify this effect and wonder if anyone on the list can do
the sums?
I am keen to exclude this as a major feedback. However, it
A key impact of the fires can also be the soot deposited onto snow and sea
ice.
I also wonder whether emissions of the CO2 into, perhaps, an inversion
layer, might increase concentrations enough to augment downward IR as the
flux will be coming from a lower and warmer layer, at least for a few
It's all kicking off now
Any ideas for geoengineering tundra to prevent wildfires? Ditches? Ploughed
breaks? Ecology changes? Controlled flooding? Fire fighting?
