Global Warming Alert

More proof that maybe we do not know as much as we thought and that we don't have as much control as we thought over the atmosphere.


Hundreds of dead penguins dot Brazil's beaches

SAO PAULO – Hundreds of penguins that apparently starved to death are washing up on the beaches of Brazil, worrying scientists who are still investigating what's causing them to die.
About 500 of the black-and-white birds have been found just in the last 10 days on Peruibe, Praia Grande and Itanhaem beaches in Sao Paulo state, said Thiago do Nascimento, a biologist at the Peruibe Aquarium.
Most were Magellan penguins migrating north from Argentina, Chile and the Falkland Islands in search of food in warmer waters.
Many are not finding it: Autopsies done on several birds revealed their stomachs were entirely empty — indicating they likely starved to death, Nascimento said.
Scientists are investigating whether strong currents and colder-than-normal waters have hurt populations of the species that make up the penguins' diet, or whether human activity may be playing a role.
"Overfishing may have made the fish and squid scarcer," Nascimento said.
Nascimento said it's common for penguins to swim north this time of year. Inevitably, some get lost along the way or die from hunger or exhaustion, and end up on the Brazilian coast far from home.
But not in such numbers — Nascimento said about 100 to 150 live penguins show up on the beach in an average year, and only 10 or so are dead.
"What worries us this year," he said, "is the absurdly high number of penguins that have appeared dead in a short period of time."
You read that correctly folks.  Colder than normal waters may have played a role in the Penguins starving to death.  So I guess the polar ice caps are not in danger of coming to a boil any time in the next 20 minutes so maybe we will survive as a species for a little while longer.
The headline here could have just as easily said, Hundreds of penguins wash up on shore, Scientists have no clue why.

Comments:
And I just read more in Montana about the glaciers disappearing with photographs of how extreme it is up there in Glacier National Park for the difference. We also must always keep in mind what global warming is supposed to mean is more extremes and a possible mini ice age some places while hotter than usual other places.

The other possibility for the penguins is what Happy Feet was talking about-- over fishing their waters. Trawlers from some countries are gigantic and scoop up everything that is in the water as they go.

Life on earth is about change is the one for sure in all this and humans (as well as most species of animals living here today) haven't been through very many of the biggest changes.
 
I realize there is a lot of real science to whatever is going on with our climate and world. I just cannot stand the hysteria that I should stop driving my car because I am personally melting the polar icecaps when the global system is far more complex than that.
I was talking to a commercial pilot last month who said there was more snow in more places in the US, such as Utah, Colorado and California in June than he had ever seen in is career.
There is still snow on a small peak near here that still has snow on it right now. I have seen snow on it on July 4th before, but never at the end of July. And on Mt. Shasta they say the glaciers are growing. Everything on earth is a cycle and keeps pretty much in balance. There are huge algae blooms in the western Pacific that are sucking up carbon and the ice caps in parts of Antarctica are growing to offset the losses in the Arctic. The earth is a wondrous and magical place that has survived for billions of years. A few years of burning fossil fuels is not going to destroy that. Eventually the fossil fuels will run out and then we will have to protest against the hydrogen power stations because there will be a shortage of that or some such nonsense.

I agree with you that over fishing is a problem in many places. Here in the US we have regulated our fishermen out of business in some places but the Vietnamese ships come in and catch everything they can without regard to our rules.
 
Well if there is to be a mini-ice age some places, then we might want to hope were not in the 'some'
