After yesterdays post on the gibberish proof of global warming due to increased Antarctic Circulation, Andrew drew attention to Jones, J. M. and M. Widmann, 2004, Early peak in Antarctic oscillation index claiming that the Antarctic Oscillation has changed in the last thirty to forty years, but is only where it was in the late fifties to early sixties.
Tas Van Ommen claims to have found that snowfall has increased in East Antarctica. Looking into his previous publications, one of the first I pulled up was Insignificant Change in Antarctic Snowfall Since the International Geophysical Year Abstract:
There has been no statistically significant change in snowfall since the 1950s, indicating that Antarctic precipitation is not mitigating global sea level rise as expected, despite recent winter warming of the overlying atmosphere.
OK, so if snowfall increases it is proof of global warming, but if snowfall decreases it is not mitigating global sea level rise.
Researching the links between drought in WA and increased snowfall in East Antarctica via a change in the Antarctic Circulation seems worthwhile. But the effects of snow accumulation on sea level would be relatively trivial.
This sort of discourse, and “proof of global warming” talk, sounds fabricated to embiggen the research.
