What is the main environmental concern when black carbon (soot) from kerosene is released into the stratosphere?

It acts as a heat absorber, causing localized atmospheric warming

Soot particles, or black carbon, released into the stratosphere efficiently absorb incoming solar radiation, leading to localized atmospheric warming at that altitude.
