Actually, looking at it again, that line looks more like an average than a regression... From that same site there this graphic: http://www.nerc-bas.ac.uk/icd/gjma/trends2010.col.pdf, showing that at 8 of the 16 stations there was a significant warming trend, with a significant cooling trend at only 2 stations.

I will agree with you that it is silly to attach a global warming angle to everything. The temperature is what it is, and you can only talk about global warming when you consider the whole planet.

You have an artificial guilt complex like so many that follow religions.

No, I have an understanding of science, the ability to read and analyse for myself, and the capacity to think beyond my own selfish ends - both in the present and extrapolated to mine, and my descendents' futures.

The hard facts

Oh dear, here we go again...

that the arctic summer holes are now closing

Are you talking about ozone? Because that has absolutely nothing to do with climate.

If you're talking about arctic sea ice, you're completely wrong.

the south pole overall has been cooling for over 30 years

Wrong. On average, antarctic monitoring stations on land have seen warming. The ocean temperatures around antarctica are absolutely clear.

You may be confused because antarctic ice is thickening. That's entirely consistent with predictions, though. A warmer planet does not mean everywhere changes in the same way. Warm air causes more evaporation from oceans, and more precipitation in places (in the case of the antarctic, more snow makes thicker ice). However, that gain is nothing compared to losses elsewhere.

You simply cannot extrapolate from individual local phenomena to the global climate, you have to look at the entire picture, which is very clear.

This article explains the science well:

http://www.skepticalscience.com/Why-is-Antarctic-sea-ice-increasing.html

that sea level rise has been going on for thousands of years since the last ice age

That's a logical fallacy. One cause (the end of an ice age) having resulted in sea level rise in the past does not discount another cause (anthropogenic emissions) resulting in sea level rise now.

If you're actually interested in educating yourself (which I'm starting to doubt) the NYT ran an accessible feature that got the science right last November:

https://www.nytimes.com/2010/11/14/science/earth/14ice.html

that more glaciers are growing than retreating

Categorically wrong. There are always localised fluctuations, but globally, we're losing glacier mass at an astonishing rate.

that mount killimanjaro's ice shrinkage is entirely a local phenomenon driven by land use

Remember what I said about local fluctuations? Look at the global picture and open your eyes. Possible localised causes around KMJ do nothing to change the extremely clear pattern of global glacier loss due to temperature rise.

are lost on you because you have a self-destructive and society-destructive false belief, fueled by hucksters with an agenda for money and power, in the "sin" of man using his mind to better his life.

Way to open and close with an ad-hominem.

Here is annual

Now, do you see any temperature trend at all there?

Not very satisfactory, but note the tantalizing abstract:

We confirm earlier findings of dramatic temperature changes in Greenland during the last glacial cycle. Abrupt and strong climatic shifts are also found within the Eem/Sangamon Interglaciation, which is normally recorded as a period of warm and stable climate in lower latitudes.

So I drill down. It's not available on the web apparently. I found it in a scientific database. Here is the full cite:

Abstract: A 3029-m-long deep ice core extending nearly to bedrock has been drilled at the very top of the Greenland ice sheet (Summit) by the Greenland Ice-core Project (GRIP), an international European joint effort organized by the European Science Foundation. The ice core reaches back to 250,000 yr B.P. according to dating based partly on stratigraphic methods and partly on ice-flow modeling. A continuous and detailed stable isotope (delta(18)O) profile along the entire core depicts dramatic temperature changes in Greenland through the last two glacial cycles, including abrupt climatic shifts during the Eem/Sangamon Interglaciation, which is elsewhere recorded as a warm and stable period. The stratigraphic continuity of the Eemian layers has therefore been scrutinized. New ice core studies, comprising cloudy band observations, deconvolution, and frequency analyses, lead to the conclusion that the climate instability suggested during the Eem Interglaciation in Greenland is likely to be real, though no conclusive evidence is available. Whereas latitudinal displacements of the North Atlantic Ocean current are considered the immediate cause of the glacial climate instability, longitudinal displacements may be the immediate cause of the Eemian instability. If so, the Eemian climate changes will be much subdued outside the Arctic region and will probably only be recognizable in sedimentary sequences of high sensitivity and temporal resolution.
