We're currently in the Modern Warm Period (bottom graph's bump on the right) of the Holocene glacial (middle graph's bump on the right, which began maybe 12K years ago), of the Quaternary Glaciation/Ice Age (top graph's far right hook beginning roughly 2.5 million years ago).
Below are the ice age cycles from the past 2.4 billion years.
This graph below are the glacial cycles from the past half million years.
Last but not least are the cycles we've experienced roughly every 1,000 years. (I said "roughly".) Our Modern Warm Period has been going on for the past 2 centuries or so. If it lasts as long as the past 3 warm periods, we've got another 2 to 4 centuries of it before we enter another cooling period.
