Try cueing the geologists and solar scientists. We're IN an Ice Age, and have been for the last ~2.58 million years. We're currently in between continental glaciations, and the next is due Real Soon Now. . . in geological terms (which is anytime from right now until 10,000 AD or so. . .)
And you might want to talk to solar scientists, as we're in a solar minimum, and they are extensively correlated with lower global temperatures. Hint: google "Solar Minimum", "Maunder Minimum", and "Dalton Minimum".
I'll also note that the warming trend that reportedly ended in 1998, still did not reach the average temperatures of the Medieval Optimum Period. . .
