The concentration of co2 in the atmosphere rose as the last ice age ended, and then stabilized for thousands of years, until humans became serious about changing the atmosphere with the start of the industrial revolution. suppose that we succeed in raising the co2 concentration in the atmosphere to a level twice as high as occurred for the thousands of years after the ice age and before the industrial revolution, and then we hold the concentration constant at that new, higher level for the next thousand years. what would happen to the average temperature of the planet?

The temperature would drop a couple of degrees and after that balance out, not sufficiently cool to cause another ice age, yet sufficiently chilly to be obnoxious 
Multiplying CO 2 is assessed to warm the Earth by in the vicinity of 1.5 and 4.5 oC, or 2.7 to 8.1oF, with some shot of marginally bigger change and next to no possibility of littler change. The physical premise of warming from CO 2 is very surely knew and cooling or no reaction is far-fetched. You may think about the normal warming from CO 2 to getting up to put another cover on the bed in the night on the off chance that you are chilly. Genuine, you may spill a glass of water into the bed, or your life partner may take alternate covers while you're up, so getting the additional cover may make you colder, however presence of mind says that getting the additional sweeping warms you. Warming from CO 2 is about as sure as warming from the additional cover—possibly countless will detonate sooner rather than later and counterbalance the impacts of the CO2 however don't depend on it.
