Do YOU see a significant trend here, hot or cold?  I don't.  IF there is a GLOBAL trend currently, the Antarctic ice seems immune.

Antarctic region HERE---->


NOTE: When discussing GLOBAL TRENDS, it is customary to include the ENTIRE GLOBAL surface area.  That means, like, adding up the hotter than baseline normal areas and subtracting, in appropriate percentile segments  ;), the cooler than baseline normal areas.

IOW Antarctica is not the globe, as in "Global Trend", get it?  ;)

But since you fine fellows are all fired up about all that ice in the OCEAN around Antarctica, let's talk about ALL of Antarctica.

All the sea ice talk aside, it is quite clear that really when it comes to Antarctic ice and sea levels, sea ice is not the most important thing to measure. In Antarctica, the largest and most important ice mass is the land ice of the West Antarctic and East Antarctic ice sheets.

Therefore, how is Antarctic land ice doing?

Shepherd et al. 2012
Figure 2: Estimates of total Antarctic land ice changes and approximate sea level contributions using a combination of different measurement techniques (Shepherd, 2012). Shaded areas represent the estimate uncertainty (1-sigma).

Estimates of recent changes in Antarctic land ice (Figure 2, bottom panel) show an increasing contribution to sea level with time, although not as fast a rate or acceleration as Greenland.
Between 1992 and 2011, the Antarctic Ice Sheets overall lost 1350 giga-tonnes (Gt) or 1,350,000,000,000 tonnes into the oceans, at an average rate of 70 Gt per year (Gt/yr). Because a reduction in mass of 360 Gt/year represents an annual global-average sea level rise of 1 mm, these estimates equate to an increase in global-average sea levels by 0.19 mm/yr.

There is variation between regions within Antarctica (Figure 2, top panel), with the West Antarctic Ice Sheet and the Antarctic Peninsula Ice Sheet losing ice mass, and with an increasing rate. The East Antarctic Ice Sheet is growing slightly over this period but not enough to offset the other losses.  There are of course uncertainties in the estimation methods but independent data from multiple measurement techniques (explained here) all show the same thing, Antarctica is losing land ice as a whole, and these losses are accelerating quickly.

See images referenced in the quote at the link below along with the full and well referenced article. :emthup:

The image below shows dovetails with images in the article quantifying the rapidly depleting Antarctic LAND ICE. As the article above claims, the CAUSE of the rapidly expanding Antarctic SEA ICE is the rapidly depleting LAND ICE.


Are you going to tell me these scientific facts and observations are "not considered 'CFS' to the lay person"? It doesn't pass the sniff test? Do you smell a global warming agenda rat here?

I don't. Check the reference!




 
Gentlemen Snowleopard and MKing, the specialty of the house, Hot Antarctic Crow, is served. Bon appetit!
