Here's a sunspot chart showing the various peaks and dips throughout the past centuries. Note the "Medieval Max". It corresponds to the "Medieval Warm Period". The "Maunder Minimum" corresponds to the "Little Ice Age", and the "Modern Max" to the recent warming trend we had been experiencing, at least until the past several years or so.

"Changes in carbon-14 concentration in the Earth's atmosphere, which serves as a long term proxy of solar activity. Note the present day is on the left-hand side of this figure."

Kewl Chart.
Did anyone besides me notice that every cooling period seems to be more intense than the pervious one?

Beam me to Planet Gore !

For those here not scientifically learned...

There is something called ‘significant figures’ used when you take measeurements. The reason being that you cannot be more precise than your measurement instruments.

If all you have is a yard stick, you can never measure something to millimeter precision.

If you have a thermometer calibrated to degrees, you can never be more precise than a half or quarter of a degree or so.

If all you have is tree rings you CANNOT say the temperature in degrees, EVER.

You can make general assumptions that one year was warmer than the previous by the width of the rings, but you can never know the precise temperature was 57 degrees on any year, if you never had a thermometer to measure the degrees. Especally temperatures 2000 years ago.

This is why global warming and the scientists who promote it are frauds

As you can see at 1100 BC everyone was hot for Helen of Troy and the temperature increased dramatically. It was all those unleaded chariots. Throughout history we fina a major source of the Climate is the Sun and Egyptian worship of the sun god added to the turmoil!

We must sacrifice maiden or at least a Gore to set things right or straitjacket him!

[Uncle Hal]

It was those darn internal combustion engines that caused all that warming in 1100 BC.

Amazing how things work out ... I was just trying to explain this to my cousin. He said he couldn’t abandon his belief in man-made global warming without proof it isn’t real. The chart with this article makes it very plain that the entire global warming cuased by humankind issue is a SCAM! Thanks so much for posting this. I made a large copy of the chart, to help my liberal cousin see the graphic evidence.

[Mrs.Z]

Excellent!

Thanks for the post.

At just a glance at the colored chart, you would never conclude “GLOBAL WARMING ALARM”. I’m impressed by the depth of recent COOLING trends as someone else mentioned.

Thought you all would like to read/see video of Al G being confronted in Chicago with another Inconvenient Truth: Climategate

Hint: It isn't pretty.

Gee, how did they record all those temperatures? Before this; In 1724 Gabriel Fahrenheit invented the first mercury thermometer.
