Looking at the Earth’s Historic Temperature

Global Mean Temperature

Here’s an interesting graphic I ran across recently. It puts some historical perspective on the whole Global Warming (sic) debate.

The conversions from Celsius to Fahrenheit: 12 C = 53.6 F, 17 C = 62.6 F, 17 C = 71.6 F

Time spans (in years) for Geological Times on chart above:
Precambrian: 4 Billion | Cambrian: 54 million | Ordovician: 44 million | Silurian: 27 million | Devonian: 57 million | Carboniferous: 60 million | Permian: 48 million | Triassic: 51 million | Jurassic: 54 million | Cretaceous: 80 million | Tertiary: 64 million | Pleistocene: 1.8 million | Today (Holocene): 13.4 Thousand

As you can see the last time the Earth was this cold was some 250 million years ago. What’s the the Global Warming Panic all about anyway?

Money? Power? Just asking…
