The Holocene is the geological epoch that started approximately 11,650 years ago. The demarcation point between the Holocene and the preceding Pleistocene is the end of the last Glacial Period, in line with variations in the Earth’s orbit. 

Instead of going down as would be in line with changes in the Earth’s orbit, temperatures and greenhouse gas levels over the past few thousands of years have kept going up as a result of activities by people. 

It makes sense to name an epoch after the dominant force shaping its climate. An earlier analysis concludes that, from the year 3480 BC, emissions by people have been higher than the amount to negate the natural trend for the temperature to fall. From 3480 BC, forcing due to activities by people was stronger than the natural fall in temperature that would have eventuated in the absence of such activities. This makes the year 3480 BC most significant as a climate marker, and it makes sense to regard this both as the base for the temperature rise from pre-industrial and as the start of the Anthropocene. 

As we keep appointing omnicidal maniacs who act in conflict with best-available scientific analysis, we are now facing a temperature rise that looks set to drive humans into extinction. Humans are now functionally extinct, and another name change is in order. Indeed, we are now in the Suicene. 

In conclusion, we have left the Anthropocene. We are now functionally extinct and we look set to drag most, if not all life on Earth into extinction with us, as we keep appointing omnicidal maniacs who act in conflict with best-available scientific analysis. We are now in the Suicene.
