This heating burns off the flat tops of shallow cumulus clouds for hundreds of miles downwind of pollution sources. With less cloud cover reflecting sunlight back to space, increased solar energy reaches the Earth's surface. It is only the soot component of pollution that causes this newly discovered cloud-burning effect. Solar heating measured during the most recent experiment in the tropics is not considered to be unique or specific to a given time and place, according to researchers. So there you have it.
Aerosols can heat as well as cool.
This makes it ludicrous for the IPCC to claim agreement between observations and models. They have known for a long time that soot aerosol leads to warming rather than cooling. Even worse for their case, removal of clouds leads to a lot more warming .
