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.” Furthermore, the paper notes, “Global climate models suggest that Antarctic snowfall should increase in a warming climate and mitigate rises in the sea level.”

Top graph shows the entire Antarctic continent has been gaining surface ice mass over the past 150 years. According to the paper, Antarctic surface ice mass is presently growing by 2100 gigatons per year.
Even the allegedly “vulnerable” West Antarctic Ice Sheet [WAIS] surface mass balance has not changed in 150+ years.
