Please allow me to revise my response to:
"The Ice Age question was a potential concern for an indefinite future of unknown timing. Again this uncertainty was a driver for initial funding on major climate science."
-- Yes, the climate cycles that lead to ice ages in the past and would have normally caused their return was being studied, But the timescales were in the tens of thousands of years, and once the impact of humanity in greenhouse gases, deforestation, etc, was taken into account it completely swamped the natural cycles.
Whether the next ice age would have come in five or ten thousand years without human intervention is an interesting but purely academic question. Global warming is a problem for our children, not the next millennium.
