Antarctica gaining Ice Mass — and is not extraordinary compared to 800 years of data

It’s difficult to say anything for sure about Antarctica because the weather is so variable. Bumper snow one year, not so much the next. (Noise and uncertainty is large). But 800 years of ice cores spread across Antarctica shows the Surface Mass Balance (SMB) is more likely to have been increasing over the last century. (Which fits with what Zwally et al found in 2012 with ICESAT satellite data).

Note the correlation of the smoothed average of the SMB (orange line) with Total Solar Irradiance (green line).

Antarctic Ice has been increasing for the last half century, and over 800 years it correlates with solar radiation. TSI: Total Solar Irradiance (Click to enlarge)  Fig. 5. (A) Mean normalised stacked SMB anomaly time series at the continental scale, calculated as described in the text (black line with positive and negative values filled in with red and blue contours, respectively) and the 40-yr central running average smoothing (orange line). The green line represents the normalised TSI anomalies, and the corresponding ±1 uncertainties are indicated by the green vertical bars.

A paper published today in The Cryosphere finds Antarctica has been gaining surface ice and snow accumulation over the past 150+ years, and finds acceleration in some areas noting, “a clear increase in accumulation of more than 10% has occurred in high Surface Mass Balance coastal regions and over the highest part of the East Antarctic ice divide since the 1960s.” 

They used 67 firn/ice core records to reconstruct the last 800 years.

From this paper we can see:

OMFG, GLOBAL FREEZING!!!!!!!!!!!!!!!!!!!

Quick, outlaw ice cube makers, air conditioning, and 7-11 slushy drinks!

No big deal. They’ve just found all the ice from the Arctic that they though was melting. So my question is, if there’s too much ice in the Antarctic, are we gonna tip over like Guam? Better get congress on this right away. Obviously guns are the least of our worries now.

LOL!

Maybe all of that mass at the bottom of the globe will stop the funny wobble of the earth that gives us our seasons....now that is frightening.

Call Congress and ask them to fund studies so that the wobble doesn't stop.

Kerry is not going be happy when he sees this.. it won’t stop him from lying.. but .. considering he was on thin ice years ago.. he bucks history.. the elite know nothing else.

It’s nice to see when ice core data analysis can be correlated closely with SAT data. Good article.
