Tropical Turtle Fossil Found in Arctic

My 50 cents on the subject. (devaluation and all)

Two things about the article. First, it seems that the world will not come to a devastating end where all life is extinct as some want the citizenry to believe. Yes in a warmer climate some species will become extinct. However, if the planet cools some species will become extinct. I bet most animals and plants will adapt like they always do. Seems to be, for the most part, beyond our control.

Second, volcanoes are thought to be the culprit. Some eruptions have from Yellowstone for instance covered a large portion of the US. That is a lot of material not letting sun through, but also sending tons of carbon dioxide into the air. Again, forces such as volcanoes are beyond our control. What are we going to do with all that carbon dioxide? Therefore I suggest we move to pass legislation to ban volcanoes. Just pass a law and everything will be fixed no matter how unintelligent, misguided and unenforceable it is. Further, we must invade other countries to force them to ban volcanoes, because of course climate change is in the US's interest. Hell, lets invade even if they did pass a ban on them. If we can't, volcanoes should be part of the carbon cap and trade system. Trade that carbon away, that will completely get rid of it. The planet will instantaneously be rid of carbon. Of course if we go to far oxygen will disappear. So if you want oxygen your unpatriotic and a terrorist.

The last place scientists expected to find the fossil of a freshwater, tropical turtle was in the Arctic. But they did.

The discovery, detailed today in the journal Geology, suggests animals migrated from Asia to North America not around Alaska, as once thought, but directly across a freshwater sea floating atop the warm, salty Arctic Ocean. It also provides additional evidence that a rapid influx of carbon dioxide some 90 million years ago was the likely cause of a super-greenhouse effect that created extraordinary heat in the polar region.

"We've known there's been an interchange of animals between Asia and North America in the late Cretaceous period, but this is the first example we have of a fossil in the High Arctic region showing how this migration may have taken place," said John Tarduno, professor of geophysics at the University of Rochester. "We're talking about extremely warm, ice-free conditions in the Arctic region, allowing migrations across the pole."

Turtles may be slow, but they're known to migrate long distances. Recent satellite tracking found a leatherback turtle traveled 12,774 miles (20,558 kilometers) from Indonesia to Oregon, one of the longest recorded migrations of any vertebrate animal.

Tarduno led an expedition into the Canadian Arctic in 2006 to study an ancient aspects of Earth's magnetic field. Knowing the barren location was rich in fossils, they kept an eye out.

The team found the fossil of a tropical, freshwater, Asian turtle. Tarduno's knowledge of Earth's crust allowed him to determine the fossil did not get moved there by shifts in the crust known as tectonic activity. The turtle died and remained where it was found. It has been named the aurora turtle.

That raised a question: How could a freshwater turtle navigate a salty ocean, which existed at the region back then?

Tarduno and colleagues think the Arctic Ocean was more separated from the rest of the world's oceans at that time, reducing circulation. Numerous rivers from the adjacent continents would have poured freshwater into the sea. Since freshwater is lighter than saltwater, Tarduno thinks it may have rested on top, allowing a freshwater animal such as the aurora turtle to migrate with relative ease.

Similar changes may be occuring in parts of the oceans today. A study in 2005 found that since the late 1960s, much of the North Atlantic Ocean has become less salty, in part due to increases in freshwater runoff induced by global warming, scientists say.

The fossil was found atop basalt, a rock associated with lava flows. That offers a clue as to what might have warmed the climate 90 million years ago.

"We found this turtle right on top of the last flood basalts — a large stretch of lava from a series of giant volcanic eruptions," says Tarduno. "That leads us to believe that the warming may have been caused by volcanoes pumping tremendous amounts of carbon dioxide into the Earth's atmosphere. There's evidence that this volcanic activity happened all around the planet — not just the Arctic. If it all happened on a short enough timescale, it could cause a super-greenhouse effect."
