OT: Catastrophic breeding season for Adelie penguins in Antarctica

All but two chicks starved to death, out of many thousands. Dwindling fish stocks? Another disastrous consequence of global warming? No, too much ice!

So much for shrinking ice sheets down there. But that was something of a fabrication anyway, apparently.

Don't confuse them with facts, their mind is made up.

Quite. As this article states it is still

"a reminder of the horrifying effects of the changing climate."

As is absolutely every freak of nature.

Standard breed to excess, live to the resource limit stuff..

Dwindling

What I learnt briefly when I did a little bit of ornithology was the MASSIVE *natural* fluctuations in populations. E.g. a hard winter will take out 90%+ of the entire wren population.

Which may take years to recover. Natural species live on the limit of the resources - there are more urban foxes than rural ones because there is more to eat in town trash.

Acually a hard winter is weather, not climate.

Forgive me asking a stupid question, but: Suppose lots of ice is falling off the Antarctic shelf because of global warming. Where does that go? It's not going to melt immediate, is it? So, maybe that creates large ice sheets.

I don't know anything about all this. But I am just pointing out that formation of large ice sheets doesn't mean that there's no global warming.

Into the sea where it floats off and eventually melts.

Icebergs is what they are then called, even if the lump of ice is bigger than Belgium. Note that such ice falling into the sea does not alter the sea level, because that part of the ice shelf off which it fell or cracked off is already floating.

Exactly. I believe the dramatic decline in house sparrows in London since the 1950's is still a mystery.

On the other hand, Parakeets are thriving in London.

Well there is a cycle. Ice forms , spreads out over the seas where its melted by warmer waters or smashed up by weather.

More sea ice might mean more snowfall, or colder waters or both.

Not really. Sealed soffits apperently. Plus less gardens and less horse feed to peck at.

Colder waters - perhaps because more ice has split off the Antarctic shelf and melted in the sea, for example?

I'm just pointing out that it isn't as simple as: More ice => No global warming.

No indeed. Except that as far as the arctic was concerned it was always trumpeted as less ice=> more global warming.

We've been to Antarctica. On the first trip there was a colony of Gentoos on Cuverville Island that had bred later than usual in the season due to the weather. The chicks, hundreds, probably into the thousands, were not going to survive the winter. This kind of event is not unusual.

On a later trip a colony of Adelies in the Fish Islands were trying to raise chicks that were in poor condition. Survival was going to be difficult. This is not unusual.

It's not climate, it's weather, but the BBC don't get it. They don't report that the ice in Antarctica now extends as far as it did in the days of Shackleton, Amundsen and Scott as evidenced by their maps.

The BBC don't even know the difference between Adelie and Gentoo penguins. The news programme reports about the deaths of the Adelies originally showed video of Adelies and Gentoos. They're now showing videos only of Gentoos!

I think the idea was less ice on the land, due to global warming, leads to a rise in sea levels.

NASA shows a rise of 85mm in the last 20-odd years, and around 250mm over the last 150 years, or so. That's not significant if you live half-way up a mountain, but more worrying if you live only a few feet above sea level.

Something has caused that sea level rise, and I assume it's generally accepted to be global warming. What's less generally accepted is the cause of the global warming.

Colder waters do expand from the most dense temperature of 4degsC. At 0C its density is approx 0.1% less than at 4C

Otherwise I agree that floating ice displaces nominally the same mass of water.

What matters most is the depth of ice on Antarctica.

In some instances, like the east coast of America, what is described as sea level rising is actual land sinking.

Sealed soffits maybe a bit but ISTR they used to nest in hedges and shrubs round our way. Not all that much horsefeed around in the 60's when they were still plentiful.

Eh? I thought it was down to the lack of horses, and the spilled grain from their feed, not to mention the proportion that goes straight through. Horses have crap ... err... inefficient digestion compared with cows.
