The legendary broadcaster and naturalist Sir David Attenborough was long unsure about the causes of the observed climate warming. In his documentary, The Truth About Climate Change, he sheds doubt and explains what convinced him.
Climate models based on purely natural processes such as solar activity and volcanic eruptions fail to explain the observed change in Earth's climate in the latter part of the 20th century. Models factoring in the human impact, that is, the increase of carbon dioxide in the athmosphere, depict the transpired warming accurately.
This graph does not show global temperature (warming) only temperature anomalies. It's also, deceptively, cut off at 1860 & 2000. Certainly because "global warming" has demonstrably ENDED despite continued rise in CO2. I can only conjecture that it's cut off at 1860 because the producer is unable to address the incontrovertible evidence that even within recorded history, global temp has been higher (and risen faster) than today, without any increase in atmospheric CO2.
