    Co2 Hemisphere
Click For Summary
SUMMARY

The forum discussion centers on the concentration of CO2 in the atmosphere, particularly comparing levels between the Northern and Southern Hemispheres. Participants express skepticism about the notion that CO2 concentrations are equally distributed globally, with some suggesting that industrial activities in the Northern Hemisphere could lead to higher concentrations there. The conversation also touches on the implications of melting polar ice caps and the potential for increased warming due to reduced albedo effects. Key references include scholarly articles and a climate report from the Bush administration acknowledging human contributions to global warming.

PREREQUISITES
  • Understanding of CO2 concentration measurement techniques
  • Familiarity with climate science terminology, including "albedo" and "anthropogenic emissions"
  • Knowledge of the greenhouse effect and its implications
  • Awareness of historical climate data and trends
NEXT STEPS
  • Research "CO2 concentration measurement methods" to understand how atmospheric CO2 is quantified
  • Explore "albedo effect" and its role in climate change
  • Investigate "anthropogenic climate change" and its scientific consensus
  • Examine historical climate data from "ice core samples" to assess past CO2 levels
USEFUL FOR

Climate scientists, environmental researchers, policymakers, and anyone interested in understanding the dynamics of CO2 concentrations and their impact on global warming.

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.)

?? 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?

Großartig, Patty wunderbar

Relax Mk I think the discussions will go to significantly higher levels.

Wunderbar either means bear or man?

Patty is marvelously behaved?

Huh?

I'm not Swiss!
