There is frequently discussion of whether or not Antarctica is warming or cooling (and if so, by how much). The image below is a useful addition to the conversation. Click the source link for the full text.
20yr of data does not a climate make.
Do you think this may have occurred before in the history of the earth?
IOW, the entire range on the graphic is within the band of uncertainty.
Over time, global temperature averages out, subject to slow tends caused by variation in solar output, volcanic output and interaction between sinks and sources of natural greenhouse gases.
Call me when they've got a few thousand years of records....
We could use some of that warming in Boston today. It’s a balmy 21 degrees right now.
Are they saying there is prime real estate coming in the next few hundred years?
Wow, what a stretch of refinement of disparate and unreliable data; I like this little nub buried in the middle of the text:
“The scientists estimate the level of uncertainty in the measurements is between 2-3 degrees Celsius.”
When the graph’s scale is only 2C at total extremes and the + or - is 2-3, the uncertainty is off the scale itself.
The really sick thing is that I have been going there for 13 years as well as to Greenland. Nothing about what your being senstionally told is outside of normal. That big hot thingy called the sun is nearly totally at fault. With all the explainations being banted about we never hear of the fact that solar flares have been higher in number in the past decade than ever noticed beofre...and yes, much like the ice ebbing and flowing we have simply not been around noticng it. But, back to the sun, if I had you stand next to a cap fire and I thre on some gasoline there would be a flare up, you would feel te heat signature. Earth gets the same thing from the sun on a massive scale and yet has barely warmed.
This is why Mars is experiencing the same warming trend and there are no evile SUV’s there and neither will you see Haliburton or Dick Cheney.
“The temperature increases were greater and more widespread in West Antarctica than in East Antarctica, where some areas showed little change or even a cooling trend. This variability in temperature patterns across Antarctica complicates the work of scientists who are trying to understand the relative influence of natural cycles and human-caused climate change in Antarctica.”
I would think this variability in temperature patterns also complicates the work of environmentalists trying to make a case for man made global warming.

Disregard the following in post #14
“(Do you have the page of text that goes with your picture?)”
Your screen name is intriguing, what does it mean, since you make frequent trips to the pole, does it involve an “extreme sport?”
Yeah, they changed it from “Global Warming” to “Climate Change” so they could fleece people year round. In New England we call it “the Seasons”.
The real cause of global warming: global warmers!
"Across most of the continent and the surrounding Southern Ocean, temperatures climbed. In some places the rate of warming approached a tenth of a degree Celsius each year, which would translate to more than two degrees over the entire period."
And then this:
"the team checked the satellite records against ground-based weather station data to inter-calibrate them and make the 26-year satellite record. The scientists estimate the level of uncertainty in the measurements is between 2-3 degrees Celsius."
