Global floating ice in "constant retreat"

New research has revealed that global floating ice is in "constant retreat" leading to fears of rising sea levels.
Its a story that we've heard a lot over the last few years and while some believe global warming may be overhyped it doesn't change the fact that the ice is indeed disappearing and that the North Pole could be ice-free as early as 2050.
The world's floating ice is in "constant retreat", showing an instability which will increase global sea levels, according to a report published in Geophysical Research Letters on Wednesday.

I think you will find that the predictions covers the troposphere as well and is equally important if not more so, so leaving it out was meant to mislead. Br Cornelius No it was excluded to prevent confusion, and to prevent you coming back and saying exactly what you're saying "Oh but it's increasing." Global warming activists don't include that altitude layer in their models of predicting future temperatures, nor does it have an effect. From a global warming perspective, I included all pertinent layers that are used in modeling.

Not true. http://www-eaps.mit.edu/faculty/lindzen/trwavaclsn.pdf Br Cornelius Apparently you have made quite the habit of citing pages that do nothing but support my argument and refute your own. Perhaps you should consider reading more than just the title of the articles that you google before submitting them. Here's an excerpt from your own source, the second paragraph: The contribution of water vapor in layers of equal mass to the climate sensitivity varies by about a factor of2 with height, with the largest contribution coming from layers between 450 and 750 mb, and the smallest from layer...

Apparently you have made quite the habit of citing pages that do nothing but support my argument and refute your own. Perhaps you should consider reading more than just the title of the articles that you google before submitting them. Here's an excerpt from your own source, the second paragraph: The range of graphs I provided for you covers the entire area discussed here--and more in fact. As I said, the reason I limited my bounds to what I did was to not confuse anyone. My graphs cover 850mb (5000 feet) to 300mb (30,000 feet). The one error that I will admit on my part is the referencing of t... [More]

The Stratosphere starts at 10Km so your wrong again. The lower troposphere is not insignificant, just not dominant. You made a valid point but thought that showing contrary data would diminish your thrust so you omitted it. It would have been better to include it and let let the data speak for itself. Cherry picking makes you look bad and it was totally uncalled for. Let the reader by the judge rather than doctoring the data. Br Cornelius Ah you're right, the diagram I was looking at when I was comparing the graphs I presented did seem a bit funny. I did indeed read the numbers wrong. So I was... [More]

As for your leaky bathtub example, it's a nice try, but you're forgetting to include saturation levels in the atmosphere. The majority of water vapor added from humans (through agricultural uses or the creation of man-made lakes), gets nearly instantly turned back into liquid H20. The remaining effect is less than .001% on the natural occurrence of water vapor. We're doing nothing to add to it. However, guess what does add to it all the time!? Volcanoes! Also, you may need to refresh yourself on the issue of which I speak--Snowball Earth. At that period, there already was negligible life due t... [More]

Wow, the whole liberal fanatic statement shows me just how much stock I should put in your opinions. And your logic of pulling out one rash statement and claiming it falsifies my arguments/evidence shows me just how much stock should be put in anything that you say.

Have 2 Gravity gen. More pic. on the way. 1 with fishing weights & 1 with water pic coming soon. It takes 2 to prove that i'm right. more info at indsloan myspace.

Cut out the sniping, you two. Besides, the AGW crowd hasn't added anything new to the Green vs. Corporate argument. I used to think they had set a timelimit, but I realized. . . everything the green movement has talked about already has a timelimit.
