NZ Herald (02 May 2009): NZ glacier findings upset climate theory
I found this when I was searching for information on NZ glacier recession rates after seeing this article on BBC NEWS. I found this link which is most interesting.
"New Zealand’s main glaciers – the Franz Josef and Fox glaciers have been advancing since the mid-1980s."
"Some valley glaciers have advanced, some have thickened in the upper trunk, and the larger ones and those with proglacial lakes continue to recede. The shift to advance is driven by an average lowering of snowlines of 67 m, equivalent to a cooling of 0.47°C if other factors are held constant.”
So what's the story? Are we getting warmer or colder down here?
The consortium of every scientist in the world has been surprised that history supports current divergence between northern hemisphere and southern hemisphere climate change. Wow, these guys must be smart, hope they are smart enough to work out how it effects the settled science.
I'm picking another great ski season coming our way this year.
"The paper published in Science magazine yesterday showed the Mt Cook glaciers advanced to their maximum length 6500 years ago, and have been smaller ever since.
But glaciers in the Swiss Alps advanced to their maximum only in the past 700 years - during the Northern Hemisphere's "Little Ice Age", which ended about 1860.
During some warm periods in Europe, glaciers were advancing in New Zealand. At other times, glaciers were well advanced in both areas.
In a commentary which accompanied the research, Greg Balco, from the Berkeley Geochronology Centre in California, said the conclusion that glacier advances in the Northern and Southern Hemispheres were not synchronised was "unexpected"."
