‘Global Warming’ alarmists are always going on about the criticality of the rise of .6 degree Celsius we saw in the last century (before it all but disappeared last year). The flawed assertions that usually follow always talk about how this is an unprecedented and abnormal rise in climatic temperature.
My question has always been “An unprecedented warming compared to what temperature standard?” The average person usually responds with something completely uninformed like “oh, you know, temperature averages of the last decade, or century.” Given that the planet’s age is around 5 billion years old and climate trends can last thousands of years, these are absolutely uneducated statements.
I recently came across the Heartland Institute that is an excellent and articulate source of common sense environmental facts. In one of their articles, “Facts Contradict Alarmist Global Warming Assertions,” they make a great point about the flaws in making recent temperatures the ‘galactic temperature standard’ that must never change:
“…Yet the fact is that global temperatures are unusually cool. For most of the past 10,000 years temperatures have been 1.0 to 3.0 degrees Celsius warmer than they are today. The 0.6 degree rise in temperatures during the twentieth century occurred from the baseline of the Little Ice Age, which saw the coldest global temperatures during the past 10,000 years.”
