A nice chart by NASA of seasonal temperature anomalies, via Climate 411 and Environmental Defense, succinctly makes a point about the cold winter we just experienced, which is that the cold temps of the past couple of months…would have been normal just twenty-five years ago.

It’ not just the winter that was very cold. The past 12 months show as scientific fact that all 4 major global temperature tracking outlets (Hadley, NASA’s GISS, UAH, RSS) that over the past year, global temperatures have dropped and cooling ranges from 0.65C up to 0.75C — a value large enough to wipe out most of the warming recorded over the past 100 years.
China had its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, there’s record levels of Antarctic sea ice, record cold in Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile – the list goes on and on.
So if ‘man’ is responsible for warming does the Enviromental Defence Fund now think ‘man’ is responsuble for the cooling?
Scientists link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. Do you agree?
Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans — and most of the crops and animals we depend on — prefer a temperature closer to 70. Do you agree?
As the above chart shows, last winter was very cold by the standards of recent years…but would have been considered routinew as recently as l981, and warm as recently as l971. Despite the inevitable seasonal ups and downs, there’s little doubt the world is warming steadily.
