Discussion Overview

The discussion revolves around CO2 concentrations by hemisphere, particularly in the context of climate change and global warming. Participants explore whether CO2 levels are equally distributed globally or if they vary between the northern and southern hemispheres, considering the industrial activities predominantly located in the north.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants question whether CO2 concentrations can be greater in the northern hemisphere due to industrialization, while others assert that CO2 is equally distributed globally.
  • One participant expresses skepticism about the scientific basis for human-induced global warming, suggesting it may be exaggerated by media.
  • Another participant points out that CO2 levels have risen from approximately 340 ppm in 1955 to 370 ppm in 2005, raising questions about whether this change is natural or man-made.
  • There is mention of other greenhouse gases and natural cycles affecting climate, indicating that the discussion is not solely about CO2.
  • Some participants challenge the validity of historical CO2 data from the 1850s, questioning the accuracy of measurements from that time.
  • Emotional responses and personal disagreements emerge, with participants expressing frustration over perceived biases and the quality of arguments presented.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the distribution of CO2 concentrations or the validity of claims regarding human impact on climate change. Multiple competing views remain, with ongoing debate about the interpretation of data and the implications of CO2 levels.

Contextual Notes

Some claims about historical CO2 levels and measurement techniques are not substantiated with references, leading to uncertainty about the accuracy of the data discussed. The conversation also reflects a mix of technical reasoning and personal opinions, which may affect the clarity of the arguments presented.

Relax Mk, it's all just an exercise in critical unbiased thinking but much more importantly, about communicating the results of that process. I'm sure we all can have a good glas of whatever sometimes :smile: reflecting on this AGW dispute.

Pattylou, I see the figures about the minimum Arctic sea ice. However I have also found this somewhere:

http://arctic.atmos.uiuc.edu/cryosphere/IMAGES/current.area.jpg

which seems to show that there have been more low records. 1999 for instance or 1993, also allegedly composed with NASA data, which makes one wonder who is fooling who.
Andre, look at the peaks in each of those years. 2005 is the lowest, and 2 million sq km less ice than the years near the beginning of the graph.

Funny, I would have used this same graph to support that the ice is thinning.

How would you characterize the trend in ice? Is it generally going up, or down?

If the answer is unimportant, then why do you bring up the summer measurements in the first place?

But errm :rolleyes: your link said:

On Sept. 21, 2005, sea ice extent dropped to 2.05 million sq. miles, the lowest extent yet recorded in the satellite record

and my link doesn't seem to confirm that. Just an observation, nothing more.

That series of refs was easy, I copy - pasted it from an article that I have submitted somewhere, which shows that the modern methods and proxies produce a more robust reconstruction of paleo temperatures and CO2 levels. So I simply correlated the proxies for the period 1000AD - 1500AD. The results would be rather disappointing for the anthropogenic global warming hypothesis. I hear that the contents are sound (not surprisingly since the calculation is done by Excel and the sources are open and available) but there were *language glitches*. :blushing: It's that very little brain thinghy. I have to have patience.

Perhaps we should continue in Dutch. German is fine too. :-p

Ummm... Ja. Deutsch. Das mache ich I am Schlaf. (Nein, nein, nicht I am Schlaf. :smile: )

(Ich erinne mir sich nur ein bischen.)

Your buddy,

?? Uh, OK? I don't undersatnd your point.
Well, you were saying how Andre has no life and must neglect family and friends to do so much posting...

Great! A reference would be good too. And, you snipped the first part of
my quote. This is a major no-no as it changes the intent of the statement. The full sentence read: "CO2, in my limited understanding, does appear dispersed over the planet."
I meant the polar ice is not dispersed, I was just cracking a joke.

Great. Are you referring to Deckart, (no references provided, ) or Andre (English-as-second-language glitches)? Your characterization doesn't describe either one of them. Note this is not casting aspersions on their characters, I am sure both are more intelligent than myself and may well have an excellent grasp of the climate arguments.
I was referring to Deckart, you were saying about his credentials and things.

How many of the links do you follow, that Andre posts? Can you put an estimate on it for me? How would you assess those links?
I follow as many as possible, if not all. And I did not notice how his links were not so scientific as they could be. However, scientific journal articles are much more difficult to find that back you up or otherwise, than CNN and New York Times type. However (again), he is obviously well-read, knows what he is talking about, and I hope no one here would knowingly lie to us. We are all (or very interested) academicly oriented, and learned people.

Thanks for giving this thought, MK.
You are welcome to thank me. :biggrin: :wink:

And is patty a female or male?
 
  • #36
Großartig, Patty wunderbar

Relax Mk I think the discussions will go to significantly higher levels.
 
  • #37
Wunderbar either means bear or man?

Patty is marvelously behaved?

Huh?

I'm not Swiss!
