'Self-reinforce' is a very strong verb  

Most anthropogenic Q released to the atmosphere does not go to melt ice. Hot combustion gasses are normally Φ under-saturated. Warm dry air often becomes hotter and dryer when combustion gasses are released into them. Automobile radiators heat air without wetting it. Hot, dry air parches the land. Forest fires break out more easily, and release much new Q, Φ, and CO₂ into the atmosphere. Warm dry air also absorbs Φ and CO₂ off oceans. Some of the Φ added to the atmosphere rises up in it and increases its permanent LQ store because moist air is lighter than dry air.

Some of the Φ added to the atmosphere rains back down. Rain falling on burnt, deforested lands usually does little to restore life there. Dry rock and bare soil have very small thermal inertia (specific heat). The ground cools rapidly when a little rain falls on it, and this cooling increases rainfall. Instead of falling in a gentle drizzle, rain thus comes in downpours that cause flash floods, mud slides and river silting. The earth is left deader and drier after the floods and fires than it was before. About 8 tons of topsoil erode off normal farmland per acre and year. Deforestation accelerates erosion and accentuates drought. Countries become less capable of supporting their populations while their armed forces are sent off to remote regions to fight terrorism. So-called terrorists are most easily turned into friends by helping them to restore their lands' fertility and to irrigate them.

As CO₂ and Φ accumulate in the atmosphere, their greenhouse effects become self-reinforcing. More Q, Φ and CO₂ released into the air from land and ocean surfaces increase their combined greenhouse effect, hence the amount of Φ and CO₂ released from the ocean, and the amounts of Q, Φ and CO₂ stored in the atmosphere- and so on. When threshold greenhouse warming effects have been attained, the process will continue to be self-reinforcing even if all anthropogenic atmospheric heating is stopped. Polar ice caps will melt away more rapidly if it is not. That is when real global warming will begin.
