    Co2 Hemisphere
Click For Summary
The Arctic ice cap is melting at an accelerated rate, with rising air temperatures over the North Pole contributing to this phenomenon. Concerns were raised about CO2 concentrations, particularly whether they are higher in the northern hemisphere due to industrial activity. While some believe CO2 is evenly distributed globally, discussions indicate that seasonal variations exist, with higher concentrations observed in winter at high latitudes, potentially linked to biomass decomposition in the Arctic. The melting of polar ice could lead to a feedback loop where reduced albedo results in increased solar absorption and further warming. The debate continues over whether current CO2 increases are primarily anthropogenic or part of natural cycles, with historical data showing fluctuations in CO2 levels. Recent reports highlight significant declines in Arctic sea ice, emphasizing ongoing climate change impacts. The complexity of climate interactions, including oceanic CO2 absorption and regional temperature variations, complicates the understanding of global warming dynamics.

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!
