Your “Science” is an alarmist blog? Not very convincing, Dude. For the record, I am degree-qualified in Chemistry and Physics, and agree there was warming between 1975 and 1998, but only 0.4 degrees. Since then the evidence is just as good for flat or at best a much reduced warming trend. If the warming is caused by human CO2 emissions, why isn’t the trend accelerating? The last 20 years has seen the greatest increase in CO2 emissions in Human history. You might also ask whether the computer models predicted the last ice age, or the warming after that ice age, given that there was no human carbon emissions at the time.
The other thing wrong with the Mann graph is that he eliminates both the Medieval Warming Period, and the last interglacial warming. We know it was 3 degrees warmer 100,000 years ago, that the Monsoons came to South Australia every year, and that the Central deserts of Australia were covered in Rain-Forest and swarmed with megafauna. I’ve got problems with that rewriting of history: I’ve seen the fossil evidence for that warmer ecology, and no “Climate Scientist” is going to convince me that “normalising the data” isn’t a fancy name for lying. When you doctor the data to support your theory, you have abandoned the scientific method. The correct response is to adapt the theory to fit the data.
