The basic principle is that the hydrologic cycle accelerates — warming enhances evaporation, increases atmospheric water content, and subsequently enhances precipitation as well

Meanwhile, here on earth, we still have the same remaining problem of our trapped thermal atmospheric content that can not escape away from Earth's self contained system that is maintained by the greenhouse gases that surrounds the earth that is said to be increasing in content, and because it increasing in content, the thermal kinetic capacity (global warming potential of certain said gases will rise with it.)

If sustained, the recently reported accelerating rate of increase in atmospheric CO2 indicates we are likely to acheive that projected 3 degree C warming earlier than once thought.

All the models I've seen rely on the assumption that an increase in atmospheric greenhouse gases will necessarily increase the long - term average temperature of the globe and that all the other mechanisms that cause or counteract warming are understood and modeled fairly accurately.
