Roy Spencer, the climate scientist with connections to big oil, like Exxon-Mobile, who's scientists knew about anthropogenic climate change in the '70s, then buried that knowledge and began a misinformation campaign?  Roy Spencer the climate scientist who has a history of " making serial mistakes that other scientists have been forced to uncover."

Sorry, that's no good.

Sure, I believe NASA.  Industrial soot no doubt has an impact on glacial melting.  But, it doesn't account for all of the melting.  Only a combination of increases in global temperature and the impact of soot can explain the world-wide retreat of glaciers.

"Scientists are also finding that glaciers reveal clues about global warming. How much does our atmosphere naturally warm up between Ice Ages? How does human activity affect climate? Because glaciers are so sensitive to temperature fluctuations accompanying climate change, direct glacier observation may help answer these questions. Since the early twentieth century, with few exceptions, glaciers around the world have been retreating at unprecedented rates. Some scientists attribute this massive glacial retreat to the Industrial Revolution, which began around 1760. In fact, several ice caps, glaciers and ice shelves have disappeared altogether in this century. Many more are retreating so rapidly that they may vanish within a matter of decades.

Scientists are discovering that production of electricity using coal and petroleum, and other uses of fossil fuels in transportation and industry, affects our environment in ways we did not understand before. Within the past 200 years or so, human activity has increased the amount of carbon dioxide in the atmosphere by 40 percent, and other gases, such as methane (natural gas) by a factor of 2 to 3 or more. These gases absorb heat being radiated from the surface of the earth, and by absorbing this heat the atmosphere slowly warms up. Heat-trapping gases, sometimes called “greenhouse gases,” are the cause of most of the climate warming and glacier retreat in the past 50 years. However, related causes, such as increased dust and soot from grazing, farming, and burning of fossil fuels and forests, are also causing glacier retreat. In fact, it is likely that the earliest parts of the recent glacier retreats in Europe were caused by soot from coal burning in the late 1800s."

And, since it's my topic, I can take it anywhere related to the original post, thank you very much.

So, YOU don't believe NASA?

Ah, if NASA is to believed, then Dr.s Christy and Spencer should be believed because it's their tabulated data! Christy did err in forgetting to factor in orbital decay a couple of decades ago (corrected), but then again Dr. Hanson has been correcting his computer models as well attempting to yet produce a predictive model. Mebbe I should pull up a hit piece on him!

As to accepting the notion that the computer model a true believer accepts as proof, it might be a good idea to first come up with a model that can predict actual correct temperatures.
