Again, simply not true. There was a possibility of human-induced cooling due to SO2 emissions from coal-fired power plants &c, but once pollution controls reduced the emissions, the problem went away.

Anyway, based on past patterns, we are due for a return to a colder climate but the margin for error is in the the thousands of years...
No, we know what drives the Ice Ages. It's the Milankovitch cycles, and that puts the next Ice Age at about 15,000 years from now.
