If greenhouse gases were held constant at today's levels, it is estimated that it would take decades for the full impact of the forcing that is already in place to be felt. The delay that's built into the system is fortunate in the sense that it enables us, with the help of climate models, to foresee what is coming. It's disastrous too, because the delay allows us to keep adding CO2 to the atmosphere.
It seems that future generations are being shortchanged.
