Anomalies off Antarctica?[edit]

Is there any explanation for the rather dramatic paired temperature anomalies in the area of the Weddell Sea? Something doesn't seem 'right' about it - two regions adjacent to each other, with diametrically opposed temperature anomalies - and strong anomalies at that, the cooler anomalies are the largest on the map.

I am not aware of any specific commentary addressed to that issue, but I wouldn't be surprised if there are data quality issues in that area. Dragons flight 20:52, 21 January 2006 (UTC)[reply]

Featured?[edit]

Hey, why isn't ths image featured? It looks like a great image, except for those areas in Antarctica. A stroHur ricane 00 1^{(Talk+Contribs+Ubx)} 22:16, 8 February 2007 (UTC)[reply]

world average[edit]

it'd be good to put a world average on that slider (I assume it's somwhere around 0.6-7?) --naught101 00:06, 14 May 2007 (UTC)[reply]

Question on the data[edit]

I seriously question this image - Basically, using the NASA site to plot the same years shows North America *cooler* than average, not hotter as shown in this image. Also, using 1200 km smoothing gives a false indication of data quality. Using 250 km indicates how much real data is missing.

1200 km - 0.39 °C above base
250 km - 0.36 °C above base

Note that the 0.42 °C warming stated in the text does not agree with the NASA values given above. In addition, the data link provided in the text *does not work*.

For search values, I used a *mean period* of October (the default) - this makes a difference, but the article did not state what value it used.

My links use *&mean_gen=10*, the link in the text uses *&mean_gen=0112* - I was not able to determine what the difference is, and there does not appear to be a way to set that via the form, but it does make a difference between North America warming or cooling.

250 km - &mean_gen=0112, 0.40 °C above base

It says annual (Jan-Dec) averages, not October averages, that's the difference. The average is still 0.42, but NASA appears to have changed their form so the link stopped working. That's fixed now. Dragons flight 00:18, 12 November 2007 (UTC)[reply]

Observation[edit]

If you'll notice the warming is primarily occurring on land at areas that have seen large urbanization over the past 30 years. --J intela (talk) 03:42, 11 June 2009 (UTC)--[reply]
