Quote: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
1.Over 800 years, Antarctic ice changes all the time, but current rates of change are not unusual. The surface mass balance (SMB) “changes over most of Antarctica are statistically negligible.” The “current SMB is not exceptionally high compared to the last 800 yr.”
2.The times with highest accumulation (1370s and 1610s) match records of solar radiation.
3.Since 1960 the ice and snow accumulation has increased by 10% in high SMB coastal regions and over the highest part of the East Antarctic divide.
Quote:Eight hundred years of stacked records of the SMB mimic the total solar irradiance during the 13th and 18th centuries. The link between those two variables is probably indirect and linked to a teleconnection in atmospheric circulation that forces complex feedback between the tropical Pacific and Antarctica via the generation and propagation of a large-scale atmospheric wave train.
Quote:“The SMB of the grounded AIS is approximately 2100 Gt yr−1, with a large interannual variability. Those changes can be as large as 300 Gt yr−1 and represent approximately 6% of the 1989–2009 average (Van den Broeke et al., 2011).”
