No one was alive 3 million years ago. Science has provided us with the knowledge of what our climate has been through time.
Science, also, tells us that humans are affecting climate change. Science, also, provides the information on how to mitigate the human factor. Either you buy into the science or you don't. Don't cherry pick climate data, review all of the climate data that science provides.
Read your own data. Please explain the unusal increase in CO2.
To provide more relevant data, for today's climate, you need to get more granular in your analysis. A graph of millions and millions of years does not provide the information of predicting the next 100 and 200 years. We need to get through that before we start looking at millions of years in the future.
