MANY geologists rather dismiss man-made climate change. On the timescales they work in, they figure nature will absorb anything we throw at it. Not David Archer.

Changing Planet: Black Carbon

When deposited on snow and ice, it changes the albedo of the surface, absorbing sunlight and generating heat.
