I have had an email question about ice core data – so I thought this new long proxy record is worth posting showing Earth cooling from the Cretaceous (time of the Dinosaurs) For larger chart. For local readers the Miocene warmth is shown in perspective – fossil coconuts from Mangonui in Northland NZ. The holocene climatic optimum warmth (4 to 7 thousand years ago) can also be seen and much more if you look carefully such as modern IPCC temperature series riddled with urban warming. Then the range of modelling results to justify decarbonizing our economies.
