I have fairly high confidence that by 2100 we will have not only the technological capability to reduce the CO2 level in the atmosphere to anything we want, but we'll be able to geo-engineer most species populations and re-freeze the glaciers etc etc.  Essentially we'll have the means to do mostly what we want with the environment, including a global temperate drop.

This is like people in 1919 worried we're eventually all going to die of polio, or people in 1819 worried we're going to eventually run out of wood to heat our homes.  The entire problem will be irrelevant due to unthinkable technology changes.

You can grow trees simply by putting seeds in the ground. Growing ice, not so easy.
