Here's a real 'climate clock', albeit one which only looks back:

Notice how the last interglacial was markedly warmer than the Holocene (the current interglacial which began ~11.700 years ago). The question to ask, and this is a serious question, is how the planet ever survived this climate crisis. If the records can be believed this interglacial is markedly cooler than the previous 3 at least, the peak temperature of the previous interglacial lies above the most pessimistic prognoses for the current era yet, still, earth abided and life did not end.

Even the current interglacial shows some marked ups and downs with a clear trend toward lower temperatures. The "climatic optimum" - the period with the highest average temperature - lies some 8000 years in the past, since then the trend has been towards lower temperatures with the eventual drop into the next cycle of glaciation somewhere in the future. If those dire predictions hold truth, how can it be that human civilisations actually came to thrive in the stone age?
To put it bluntly, this type of scaremongering only serves to discredit the concept of anthropogenic climate change, it is the climatic equivalent of 'there are 5G transponders in vaccines'. The more this type of apocalyptic messaging is pushed, the more the messengers will start to resemble religious zealots instead of objective agents.

- hagbard_c 5y agoHumans survived glaciation and started to thrive at the climatic optimum so they'll survive this blip on the temperature graph as well. Some species could not adapt to the warming climate and the resulting changes in vegetation - from the cold open plains of the mammoth steppe [1,2] to a largely forested Eurasian continent, partly due to the disappearance of large herbivores which kept the trees at bay - and/or the increased predation by other species (humans being an important example of those) and died out, e.g. there is not much left of the Pleistocene megafauna [3,4].
