IMO, yes. I have a long held theory we're about to enter another Ice Age cycle due to the earth's interior heat build up being released, warming the oceans, increasing atmospheric moisture content, increased snowfall, increased volcanic activity (1,000s below the sea for ever one above), SO2 increases, ash increases, all of which reflect sunlight and lowering the earth's average global temperature.
We'll warm back up in about 100k years, tho. So there's that. ;)
