I find it very annoying when people assume that an unusually warm day in the middle of January, for instance, is evidence of global warming. And on the flip side, while it’s delicious when the latest event to lament global warming is called off because of a blizzard, I know that doesn’t actually disprove the global warming thesis.

Yet it is interesting to see drips of evidence making their way into the public dialogue about climate change that contradict the global warming narrative. Here’s the latest on the recent big drop in global temperatures:

All four major global temperature tracking outlets (Hadley, NASA’s GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.

A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C — a value large enough to wipe out nearly all the warming recorded over the past 100 years. All in one year’s time. For all four sources, it’s the single fastest temperature change ever recorded, either up or down.

What’s going on here? Turns out, it isn’t just greenhouse gases that determine the temperature, the sun has a little something to do with it:

Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn’t itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.

The article goes on to warn that a cooling trend will have far worse effects on mankind than warming. Perhaps another reason not to embrace economy crushing policies to combat the global warming specter? It’s just a thought…
