Western Antarctica Ice Sheet warming faster than thought
BBC: The Western Antarctic Ice Sheet is warming nearly twice as fast as previously thought, according to a new analysis of temperature records. US researchers say they found the first evidence of warming during the southern hemisphere’s summer months. They’re worried the increased melting of ice could contribute to sea-level rise.
The study has been released by the journal “Nature Geoscience.”

For those who might be keeping score, we just passed the 333rd consecutive month of global temperatures above the 20th-century average.
November 2012 was the fifth-warmest November since records began in 1880, the National Oceanic and Atmospheric Administration said in its monthly climate report. The agency calculated that the 10 warmest Novembers on record have all occurred within the past 12 years.
the apocalypse begins…
I was thinking of writing a lengthy post about climate change denial being completely unscientific nonsense, but then geochemist and National Science Board member James Lawrence Powell wrote a post that is basically a slam-dunk of debunking. His premise was simple: If global warming isn’t real and there’s an actual scientific debate about it, that should be reflected in the scientific journals.
He looked up how many peer-reviewed scientific papers were published in professional journals about global warming, and compared the ones supporting the idea that we’re heating up compared to those that don’t.
What did he find? Check out the pie chart above. That pretty much sums it up….

Some quotes about climate change from a growing collection I keep.
If we don’t listen to the scientists, at least we can listen to the animals?!?
“Just how much is 200 million tons of ice? Roughly, it’s the amount needed to fill enough railroad coal cars to encircle the Earth.”
that analogy does not make things any clearer…
With the average temperature on Earth in October becoming the 332nd consecutive month at a higher-than-normal mark, we’re defining the new normal for a whole generation.
And that’s not a “new normal” that we should be okay with. Because a warming Earth with frequent droughts and supercharged storms could make Hurricane Sandy look like an afternoon sprinkle.
