We have had 4 Ice Ages in the last 2 million years, with big warm-ups in between. Could somebody explain why the wild cycles, and why the current period is different?

The current period is different because of anthropogenic global warming. The current period is different because humans are putting billions of tons of carbon into the atmosphere every year.
The present is often different from the past. Change happens. There has been non-anthropogenic climate change in the past. It does not follow that there is no anthropogenic climate change now.
I had the flu once. It does not follow that I can't get cancer. Yesterday was Saturday. It does not follow that today can't be Sunday.
