A reminder of global temperature trends through geologic time

Puts where we are now in perspective. I found myself looking for paleoclimate data from Australia – failing to find any charts going back through the Tertiary. So I thought it worthwhile reminding ourselves of the long term global trends.
Climate change during the last 65 million years – thanks to Robert A. Rohde for the chart below.

There is also a chart going back to the Cambrian – the first common ocurrence of fossil life forms – 540million years – chart by Glen Fergus. Note the timescale on these charts varies greatly.
