West Antarctica Warming Faster Than Thought
New submitter dgrobinson writes "NY Times reports that West Antarctica has warmed more over the last half century than was first thought. A paper released Sunday by the journal Nature Geoscience (abstract) found that the temperature at a research station in the middle of West Antarctica has warmed by 4.4 degrees Fahrenheit since 1958. That is roughly twice as much as scientists previously thought and three times the overall rate of global warming, making central West Antarctica one of the fastest-warming regions on earth."
Water almost up to my keyboard.
Their they're doing there hair.
Which way is west in antarctica?
Face north, then turn left.

You cannot tell with a single coin flip whether the coin is fair (50% probability of heads) or not. You cannot predict any particular flip of the coin. But if you flip a coin 1000 times and it comes up heads 659 times, you can say with a high degree of confidence that the coin is not fair. You still cannot predict any particular flip, but we can predict that we would see about 66 heads if we flipped the coin 100 times. If tomorrow we flip the coin 1000 times and it comes up head 831 times you have a high degree of confidence that the distribution of heads and tails changed since yesterday.
Weather is like a single coin flip. You cannot tell in advance easily whether it will rain or not or exactly what temperature it will be. But we can make statements about the average temperature in January or the average number of rainy days in April. If we see those values change over time, as we have all over the Earth, you can say that the climate is changing. With enough measurements over a long enough period of time, you can see the climate change at only one weather station. If we also see the same thing happen at thousands of other weather stations over decades, and we observe the ice sheets melting and the humidity increasing, then that's clear evidence of the climate changing.
That's the difference between weather and climate. Weather determines what you wear on a particular day. Climate determines what clothes you have in your closet.

...is an interesting place. It "stick out" more than the rest of the continent and hence is surrounded by more water, and it's home to at least 6 surface volcanoes (http://icecap.us/images/uploads/AntarcticVolcanoes2.jpg).
A few years back scientists discovered at least a bunch of sub-oceanic volcanoes with at least one merrily bubbling away. They remarked on how warm the waters were and how this had caused unique "oases" of lifeforms all along the extent. (http://www.antarctica.ac.uk/press/press_releases/press_release.php?id=1541}
These and the unusual "surrounded by water" nature of this area are more likely contributors to localized melting.

Unlike Earth, whose temperature varies as one moves closer to or farther from the equator, Jupiter's temperature depends more on height above the surface. This is because heat is driven not by the sun but by the interior of the planet. Nice try, though!

It will be hard calling you six years ago.

We would expect to see some record lows even during warming. The important point is that there are many more record highs being hit in recent years than record lows, which is exactly what you'd expect if the climate is warming. You can't tell whether the Earth as a whole is warming or cooling based on cherry-picking data.

Well, if we manage to melt Antartica, we are in hot waters!
Here is the sea rise interactive map. You can choose how much sea level rise and see if you still live on land. I recall melting the whole Antartica would cause a sea rise of 70 meters. I do not know if it includes water thermal dilatation, but I hope it does.
Yes. No need to retract your PhD, your whole domain is a sham.
Yes. That's why we produce the same structural data as the X-ray crystallography guys do with a completely different method.
Oh, I forgot to mention, the above was only the digital processing. Before the raw data - i.e. the signal of the receiver coils - get digitized, they run through a preamp, a couple of analog filters, the main amp and the a/d-converter, each component, even the cables in between, adding artifacts and distortions to the signal.
In summary, every non-trivial measurement yields heavily processed data. You just need to be aware how exactly you processed them. Science, it works, bitches.
