Re: [Phys-l] global temperatures



No..there was a thread--maybe it was of PhysSoc about how the ice was being measured--from photos, which don't show thickness. I forget all the details now, just that there was controversy over how the amount of ice was being determined. Someone had offered that the ice was 'gone' but that certainly is not yet the case. Again, the 'controversy' that was being discussed (and I offered this just as an aside anyway) was over the data collection--basically how reliable IS the data. My point only being that even the 'data' in the complex issue is sometimes in question. I see that John Sohl has just offered a partial solution to the data question, but a solution still awaiting a launch window. Does this mission require the Shuttle--if so, it is probably dead. If not, what's the hang up?

Rick,

The only news I've heard recently is that the melting appears to be
occurring much faster than any of the models had predicted, but that
wouldn't seem to constitute a "controversy" in the context of this
discussion. Is that what you are referring to?

Controversy? There's also controversy about evolution, and
controversy
about whether astronauts landed on the moon, and controversy about
whether Elvis is dead. Controversy is not evidence. Please let's
stick to the evidence.


The Controversy is exactly over the evidence--just how much of the
polar
ice has melted.

But if what one gets on this list are flippant and derogatory
responses......................
