It is much more informative if the graph goes back enough to see that CO2 levels have been significantly higher than they are today in the earths history. There is clearly a desire to create alarm rather than present the facts as they are, and that in turn creates mistrust.
I concur. But would add that the temperatures and ecological environment in previous times were very different from current ones. Neither we nor our foodstuffs would have flourished in some previous epochs. Maybe the emphasis on the current period is merited.
