400,000 Year History of Climate for Dummies

Don't miss this pictorial presentation of global climate history by JStorrsHall For a bit of background on how temperatures are derived from ice cores (using isotopes -- not CO2 in air bubbles) from up to many thousands of years ago, see here.

Briefly: In a warmer year, more sea water evaporates which causes a relative excess of deuterium (and O18) in the atmospheric water vapour. Rain and snowfall deposits this excess deuterium. If that year's precipitation is trapped in ice over many years (as in Greenland or Antarctica), scientists can take ice cores hundreds or thousands of years later, and determine the approximate relative temperatures over time.

The Vostok core is one of the most famous ice cores in climate research.

The record presented by Jouzel et al. (1987), based on data in a 2083-meter ice core from the Russian Vostok station in central east Antarctica, was the first such record to span a full glacial-interglacial cycle. Drilling continued at Vostok until January 1998, reaching a depth of 3623 m, and a corresponding time of ~420 kyr BP. More recently, a 740-kyr deuterium record has been extracted from an ice core taken at Dome C (EPICA Community Members, 2004). Deuterium fractions were determined in meltwater from 55-cm long sections of the ice core the surface down to the bottom of the core. _ORNL

The ice core graphs that J Storrs Hall displays illustrate a panoramic perspective of relative temperatures over time spans from hundreds of years to hundreds of thousands of years. Once you have taken a look at the series of graphs of ice deuterium over time scales from hundreds to hundreds of thousands of years, you will begin to understand the global political climate campaign a bit better.

Other types of isotopic analyses can be used for re-assessing the climate record from tree rings and sediments. Such analyses may bring climate science back from the brink of disaster to scientific respectability.

The ongoing circus that is Copenhagen is a reflection of modern human's tendency to look away from the evidence. Money-grubbing dictators of the third world are salivating at the prospects of wealth redistribution from advanced nations to undeveloped dictatorships -- one of the main pillars of the Copenhagen "agreement."

If you are like most people, you have no idea what is being contemplated for your future. Time to wake up.

Update: Here is another fantastic chart-filled look at real temperature trends -- this time in Australia over the past 130 years or so. Honestly, my friends, for truly curious, intelligent, and open-minded persons, it is becoming almost impossible to believe in the dogma of carbon catastrophe.

Unfortunately it is carbon hysteria that is being drummed into the heads of almost all schoolchildren from pre-school thru university. What should be done to the people responsible for this scandal? Nothing good.
