[edit] Temperature Data

CRUTEMP3 is land only. I would suggest using HadCRU3 instead which is land and ocean. Dragons flight 01:12, 11 March 2007 (UTC)

Thanks for the suggestion. I've updated it. -- Leland McInnes 02:11, 11 March 2007 (UTC)

Also, you seem to be using the January data rather than the annual average (which is the last column). Dragons flight 02:16, 11 March 2007 (UTC)

Excellent spotting, I was indeed picking the wrong column (I should be more careful when subbing in new data to an existing script). Thanks. -- Leland McInnes 02:49, 11 March 2007 (UTC)

Could you please label the thick red line and thick orange line? They appear to be some sort of running mean but of what duration? It is rather unscientific to add lines to a graph without indicating what they represent. Especially when the unlabled line is given such heavy wieghting.

In comparison to the Hadley plots linked in the POV comment below your plots dampen out important cyclic behaviour in temperature which does relate to sunspot activity. The long time constant also means your plot stops before the current leveling off. Both of these points could be misleading.

It would also be great if you could attach the gnuplot script that generated these excellent plots.

Thanks.

[edit] POV

Obviously created to support the viewpoint that sunspots have nothing to do with terrestial air temperature and that CO2 does.

How about creating a pretty graph to illustrate the opposite view, too? Baliunas and others have some interesting correlations. --Uncle Ed 15:29, 23 March 2007 (UTC)

I think "nothing to with terrestrial air temperature" is a little strong, as there are some correlations visible. If you have something else in mind then by all means point me toward some appropriate data and I'll plot it. -- Leland McInnes 21:29, 23 March 2007 (UTC)

What are you talking about? The correlation is pretty clear up until 1960, which is when CO2 emissions started to shoot up rapidly. The graph shows that sunspots do indeed affect temperature ( in fact the two graphs are fairly in synch up until 1960 ). It also shows that CO2 concentration has an even greater effect. 137.205.236.52 20:03, 11 April 2007 (UTC)

When you look at the graph for temperature it points upward, as if indicating a further rise in temperature. If you look at the same graph on the original homepage, [1], it shows a stable temperature for the last years?--ElThyge 06:50, 25 July 2007 (UTC)
