The report explains that researchers analysed a long continental drill core that coveres the period of the Pleistocene ice age.
Analyses of the longest continental sediment core ever collected in the Arctic, recently completed by an international team led by Julie Brigham-Grette of the University of Massachusetts Amherst, provide “absolutely new knowledge” of Arctic climate from 2.2 to 3.6 million years ago.
As soon as they quote dates of this magnitude it confirms that they are looking at the evidence through the lens of uniformitarianism—they are extrapolating present processes into the past. It’s this assumption that leads to age-interpretations of hundreds of millions of years. This philosophy ignores biblical history and the global Flood of Noah’s time, some 4,500 years ago. Biblical geologists interpret the period covered by their drill core as early post-Flood. (The Pliocene they mention may be very late Flood—the closing weeks of it.) The post-Flood Ice Age lasted for a period of some 700 years. It was driven by warmer oceans that were heated by the volcanic activity that occurred during the Flood.
And not surprisingly Brigham-Grette et al. discover exactly what creationist geologists have been talking about for decades: the climate in the Arctic was warmer in the past.
“One of our major findings is that the Arctic was very warm in the middle Pliocene and Early Pleistocene [~ 3.6 to 2.2 million years ago] when others have suggested atmospheric CO2 was not much higher than levels we see today.
In other words, CO2 was not a factor in the higher ocean temperature.
The problem is that because uniformitarians deny that the biblical Flood happened and ignore its consequences, they cannot expalin the Pleistocene Ice Age, for which the geologic evidence is very clear. So, even though their research shows that the warm oceans were not correlated with CO2 levels, that is not what they concluded. Rather, the authors still maintained that CO2 was factor because they already believed it was.
“In other words, the Earth system response to small changes in carbon dioxide is bigger than suggested by earlier climate models,”
This conclusion is almost unbelievable.
The quality of scientific research into past climates and the factors that drive them would be greatly improved if researchers were better read on biblical geology. As it is, researchers do not seem to be able to see that their models do not work (see Noah’s Flood and global warming).
Creationist models of the post-Flood Ice Age have been discussed in creationist literature for decades, and are the only models that provide a plausible mechanism for the cause of the Ice Age. (For more information go to Creation.com and search for Ice Age.) According to these models, earth’s past climate was not driven by CO2. Rather it was a consequence of the enormous global thermal disturbance of the Flood. In the centuries after the Flood the earth’s heat balance returned to equilibrium, and its climate stablilsed.
Update 15 May 2013:
Originally the text said the researchers found “the oceans were warmer” but it now says they found “the climate in the Arctic was warmer in the past.” Thanks to Ashely Haworth-Roberts for pointing this out. Creation scientists have been talking about warmer climates in this area for a long time. See for example: The extinction of the Woolly Mammoths. And creationist scientists have long considered warm oceans as the cause of the warm climate. See for example Rapid changes in oxygen isotope content of ice cores which presents oxygen-isotope evidence from ice cores suggesting the oceans were warmer immediately after the Flood.
