Idiotic Iceberg Theory and Penguins

It seems an Adele penguin colony is experiencing a serious reduction in numbers due to the running aground of an enormous iceberg in antarctica, lengthening their feeding trips by 120 km. (H/T Wattsupwiththat)

The presser: 

According to new research co-authored by the University of NSW’s Climate Change Research Centre and published in the journal Antarctic Science, the colony could be wiped out within 20 years unless the sea ice breaks up or the iceberg, with an area of about 2900 square kilometres, moves. 

“Iceberg doesn’t really do it justice,” Professor Turney said. “It’s like a small country, it’s enormous.

“As the planet warms you’re going to get more ice melting. The reality is, more icebergs will be released from Antarctica and just embed themselves along the coastline, and make the travelling distances for some of these colonies even further than they have been.”

The scientist in question is our friend, Chris Turney, from a couple of years back who ended up marooned with his team in the Antarctic ice, with some embarrassment one gathers from reading the various commentaries of the time. And he does not understand ice cap physics judging his explanation for the massive iceberg affecting the penguins,

Melting icecaps do not produce more icebergs: they don’t produce icebergs period but simply retreat back into the Antarctic continent.

On the contrary iceberg production is the result of excessive ice production at the Antarctic.

Little wonder the good professor got into difficulties last time, when he can’t understand that iceberg production is the result of massive ice production at the poles. So much ice is produced that it spills outwards away from the poles forming icebergs.

About Louis Hissink

Retired diamond exploration geologist. I spent my professional life looking for mineral deposits, found some, and also located a number of kimberlites in NSW and Western Australia. Exploration geology is the closest one can get to practicing the scientific method, mineral exploration always being concerned with finding anomalous geophysical or geochemical data, framing a model and explanation for the anomaly and then testing it with drilling or excavation. All scientific theories are ultimately false since they invariably involved explaining something with incomplete extant knowledge. Since no one is omniscient or knows everything, so too scientific theories which are solely limited to existing knowledge. Because the future always yields new data, scientific theories must change to be compatible with the new data. Thus a true scientist is never in love with any particular theory, always knowing that when the facts change, so too must he/she change their minds.
