White House Easter Egg Roll tickets go to kids of military

March 20, 2013

Not big news — they do this almost every year — but I want to put down the anchor on this story.

"EASTER EGG ROLLING, WHITE HOUSE" &q...

Why do I want to anchor it?  In about three days, if tradition holds, I’ll get an e-mail from some vet madder than hell that Obama shut out the kids of military veterans from the Easter Egg Roll; the story he sends will probably claim Obama changed it to a Ramadan Relleno Roll, or something.

I post it here so I can find it quickly, then.  Obama H8ers will distort every piece of good news.  You can see the drumbeat start in the “More” section below.  A Continuing Resolution passed the Senate today, and is expected to win approval in the House tomorrow, providing funds to continue the Easter Egg roll on April 13, as well as the rest of the government through the end of the Fiscal Year.

Update:  Turns out that Fox News had already slammed Obama, falsely, for keeping the Egg Roll on the calendar.  As Mediaite reported, Fox News’s Megyn Kelly charged it was all politics, prompting White House press guy Jay Carney to explain the event is paid for out of donations, not out of the budget.


Annals of global warming: No, polar bears are not “fine” — suffer from loss of sea ice

Press release from The Journal of Animal Ecology (links added here):

For polar bears, it’s survival of the fattest

One of the most southerly populations of polar bears in the world – and the best studied – is struggling to cope with climate-induced changes to sea ice, new research reveals. Based on over 10 years’ data the study, published in the British Ecological Society‘s Journal of Animal Ecology, sheds new light on how sea ice conditions drive polar bears’ annual migration on and off the ice.

Led by Dr. Seth Cherry of the University of Alberta, the team studied polar bears in western Hudson Bay, where sea ice melts completely each summer and typically re-freezes from late November to early December. “This poses an interesting challenge for a species that has evolved as a highly efficient predator of ice-associated seals,” he explains. “Because although polar bears are excellent swimmers compared with other bear species, they use the sea ice to travel, hunt, mate and rest.”

Polar bears have adapted to the annual loss of sea ice by migrating onto land each summer. While there, they cannot hunt seals and must rely on fat reserves to see them through until the ice returns.

Dr. Cherry and colleagues wanted to discover how earlier thawing and later freezing of sea ice affects the bears’ migration. “At first glance, sea ice may look like a barren, uniform environment, but in reality, it’s remarkably complex and polar bears manage to cope, and even thrive, in a habitat that moves beneath their feet and even disappears for part of the year. This is an extraordinary biological feat and biologist still don’t fully understand it,” he says.

From 1991-97 and 2004-09, they monitored movements of 109 female polar bears fitted with satellite tracking collars. They tagged only females because males’ necks are wider than their heads, so they cannot wear a collar. During the same period, the team also monitored the position and concentration of sea ice using satellite images.

“Defining precisely what aspects of sea ice break-up and freeze-up affect polar bear migration, and when these conditions occur, is a vital part of monitoring how potential climate-induced changes to sea ice freeze-thaw cycles may affect the bears,” he says.

The results reveal the timing of polar bears’ migration can be predicted by how fast the sea ice melts and freezes, and by when specific sea ice concentrations occur within a given area of Hudson Bay.

According to Dr. Cherry: “The data suggest that in recent years, polar bears are arriving on shore earlier in the summer and leaving later in the autumn. These are precisely the kind of changes one would expect to see as a result of a warming climate and may help explain some other studies that are showing declines in body condition and cub production.”

Recent estimates put the western Hudson Bay polar bear population at around 900 individuals. The population has declined since the 1990s, as has the bears’ body condition and the number of cubs surviving to adulthood.

Because polar bears’ main food source is seals, and these are hunted almost exclusively on sea ice, the longer bears spend on land, the longer they must go without energy-rich seals. “Climate-induced changes that cause sea ice to melt earlier, form later, or both, likely affect the overall health of polar bears in the area. Ultimately, for polar bears, it’s survival of the fattest,” says Dr. Cherry.

He hopes the results will enable other scientists and wildlife managers to predict how potential climate-induced changes to sea ice freeze-thaw cycles will affect the ecology, particularly the migration patterns, of this iconic species.
