So much for ice ages

Greenhouse gas rise will delay next ice age by as much as 100,000 years, scientists say

Ill informed climate change denialists will sometimes try on an argument along the lines of "well, warming is better than an ice age, and as one of those may be just around the corner, we shouldn't worry about pre-empting it by warming the planet now." 

They conveniently forget Hansen's long standing rebuttal that  "..a single chlorofluorocarbon factory would be more than sufficient to overcome any natural tendency toward an ice age. Ice sheets will not descend over North America and Europe as long as we are around to stop them."

And in any event, latest estimates of an ice age were for the next being millennia away, as this article explains.
