How are weather and climate affected by changes in the environment?

The entirety of the scientific community accepts that CO2 traps heat; this is science established over a century ago, and to do so would deny that a greenhouse effect even exists.

The earth stopped coming out of the last ice age thousands of years ago. Within the last century, however, natural variability cannot explain the warming that has occurred; the radiative forcing of the solar variability is an order of magnitude below what has been observed.
