This first chart is from The big picture: 65 million years of temperature swings. It clearly depicts the extent of the current global warming catastrophe within the context of the past 10,000 years:
Note the infamous “hockey stick” shape at the end of the chart which clearly shows the unprecedented extent of today’s post-little-ice-age warming.
But maybe 10,000 years are not enough to establish a pattern: The next chart is from Climate4You.com, using reconstructed global temperature over the past 420,000 years based on the Vostok ice core from the Antarctica:
Half a million years not floating your boat? How about a reconstruction of temperature over 65 million years:
All in all, I think we can safely conclude that global warming is unprecedented, impending, man-made, and catastrophic. The science is settled, and if you have the slightest shred of a doubt you are an annoying, ignorant, bigoted, Republican, anti-scientific big business oil/coal/whatever lobbyist who clubs baby seals and eats their hearts for breakfast!
