Selected graph axis reversal?

Why do most of your graphs go from left-to-right, while some, which you have placed prominently at Greenhouse gas (and Global warming, as corrected there), flow from right-to-left? --James S. 19:25, 28 December 2005 (UTC)

It is convention in geology and long duration paleoclimate to place the present day at the left and have "years ago" increase towards the right. I'll admit to not being entirely consistent about this, but the longer the record, the more likely I am to plot it in paleo style with the present at the left. Also, some of these pictures have been prepared for other reasons, and so reflect the orientation needed at that time, and not necessarily what fits best in Wikipedia.

I'm sorry, but that is just completely new to me. I've never seen a time-series graph in an English language journal or scholarly publication that runs from right to left. Admittedly, I've not read any geology texts lately, so perhaps my suspicion is unfounded. And yes, the inconsistency bothers me a lot. What is your background in the field of paleoclimatology? —James S. 01:29, 29 December 2005 (UTC)

Thank you for preparing the original graphs. I have reversed the time orientation on both images so that they are now consistent with the other images in both articles, and released them under the same conditions as you have. Hu 03:03, 29 December 2005 (UTC)

That's fine by me. Dragons flight 03:51, 29 December 2005 (UTC)

Temperature anomaly?

Is that std error? __earth 01:46, 10 January 2006 (UTC)

Anomaly in this sense just means difference from some reference value, in other words, its the same as "temperature change", "temperature difference", etc. Dragons flight 01:50, 10 January 2006 (UTC)

I'm apologize for asking an elementary question but how do we get the reference value? Moving averages? __earth 03:50, 10 January 2006 (UTC)

Inoted your request for suggestions on realclimate. After working with you on Glacier Retreat I would like to see your map graphic of 1970-2005 mass balance focus on the 1985-2005 period. This is the period of noted negative mass balance and the contrast to the 1970-1985 is notable. Secondly Hurricanes, the changing numberand intensity as noted by the NHC would be cool to see take flight.Peltoms 18:27, 15 March 2006 (UTC)

Graphs

Great job on the global warming-related graphs. It really helped me understand the article. (^'-')^ Covington 06:53, 11 April 2006 (UTC)

Solar Activity

The Dye3 10Be record is not the only one available. In particular, the South Pole data are as good quality (Bard et al 2000). However, SP has a different behaviour to Dye3 - no big trend at the end, and a different number of cycles over the common period. Absent any particular reason to prefer one over the other, basing conclusions on only one of them is not wise.

Zero Point Date

Thanks for the great graphs!

If I may offer a suggestion, it would be helpful to give the date of most current data for charts that have "0" for the current end point.

I think it's fascinating that CO2 levels have already doubled the normal 80-100 ppm rise between glacial periods. Tobyw 11:26, 26 September 2006 (UTC)

Atmospheric Carbon Dioxide Graph

Hey, great work. I'm curious about your Atmospheric Carbon Dioxide: Measured at Mauna Loa, Hawaii graph, as it is now featured on the Wikinews main page. I think the inset Annual Cycle diagram may be a little deceiving to people that don't read the description in the image's credits. They may see it as an average annual cycle, not the average of each month over all years. I hope that made sense :) Thanks again 198.162.158.16 22:01, 23 October 2007 (UTC)

Which Software?

Hey, congrats for the great job! I wast just wondering: which program do you use to make these fantastic graphs? See ya! --81.230.179.24 (talk) 19:57, 10 August 2009 (UTC)
