What is the big deal about glaciers? They have waxed and waned for ever.
What is their ideal length? who determined that?
In the little ice age, they were much longer than now. Yes its warmed since then. 5000 years ago, they were shorter than now.
In 100 years time they will be longer! So what?
They wont ever stay the same length, so why try to force them to do that?
History shows that the human race does flourish in warmer climates and does poorly in colder climates. Be more concerned about a cooling cycle than any warming cycle.
