Little Penguins of Antarctica
Adélie Penguins (Pygoscelis adeliae)are doing well but what is happening to Little Penguins (
Eudyptula minor)?
We can always count on the ABC to ramp up climate change alarm and so, in December 2009, we had Mark Colvin telling us
how Little Penguins were threatened by climate change:
"Scientists monitoring Australia's most famous population of Little Penguins have had a scare, after some chicks died of starvation because their parents had to go farther afield than usual to find food."
Predictably, we were told that it's a problem that could become more common as climate change takes hold and trust the media to find an alarmist scientist to add to the drama. Dr. Andre Chiaradia reported:
"There's new evidence that storm activity can affect food supplies and there's concern that could happen more often as the climate changes."
And:
"We are actually concerned in the future because with this story of global change and global warming those days of storms is going to be more often."
To their credit, in July 2013 the
ABC interviewed Research Manager of the Phillip Island Nature Parks Dr. Peter Dann who gave us some good news:
"These chicks are fatter, they've grown faster, the parents have brought back more food. The parents have been heavier than normal right through the breading seasons."
King Penguins
So Adélie Penguins (
Pygoscelis adeliae)and Little Penguins (
Eudyptula minor) are doing well but what about King Penguins (
Aptenodytes patagonicus)?
Firstly, we read in the media how the King Penguin population on Macquarie Island was on the brink of extinction due to hunting to the extent that by 1894 the Isthmus colony was extinct and by 1930 the Lusitania Bay colony had been reduced to 3,400 birds.
More good news!
Dr. Tim Heupink, and colleagues from Queensland's Griffith University, noted that, since the island became a wildlife sanctuary in 1933, a state reserve in 1972 and a World Heritage site in 1997, not only have King Penguin numbers recovered, they have expanded their colonies extending them north from Lusitania Bay on the east coast to Green Gorge, Sandy Bay and the Isthmus.
So Adélie Penguins (
Pygoscelis adeliae), Little Penguins (
Eudyptula minor) and King Penguins (
Aptenodytes patagonicus) are doing well but perhaps Emperor Penguins (Aptenodytes forsteri) are in trouble.
Tim McDonnell (
Mother Jones, June, 2014) breathlessly told us:
"Our Inability to Deal With Climate Change Is Going to Kill the Penguins.
And:
"Many Antarctic Emperor penguin colonies could decline by more than half in less than a century."
And:
"It's time for Emperor penguins to become the new poster children of climate change."
And:
"Thanks to declining concentrations of sea ice, two-thirds of Antarctica's Emperor penguin colonies could lose more than half their population by 2100."
Such alarmism ignored research conducted by Dr. Peter Fretwell of the British Antarctic Survey. Fretwell used satellite imagery to show that Emperor Penguins move between old colonies and establish new colonies.
Dr. Michelle LaRue, from the University of Minnesota agrees:
"This suggests that emperor penguins move among colonies. That means we need to revisit how we interpret population changes and the causes of those changes."
Satellite imagery estimates have now more than doubled the population of known Emperor Penguins with two new colonies having been identified.
LaRue notes that, if we want to accurately conserve the species, we really need to know the basics.
It would appear then that slightly increasing concentrations of atmospheric carbon dioxide and temperature stasis over 20 years have done absolutely nothing to threaten the Penguins.
Returning to Meredith Hooper's book I noted how
"For clear overviews" about global warming threats to Arctic and Antarctic animal life, she recommended Tim Flannery's book,
The Weather Makers (London, 2005) and Al Gore's movie,
An Inconvenient Truth (New York 2006).
Enough said.
