Great mass extinction caused by ice age, not climate change

During the Permian-Triassic boundary 250 million years ago, the Earth was enjoying some of its warmest temperatures when it was interrupted by a catastrophic cooling event.

The new discovery shows how an Ice Age forced a massive die-off of most marine life, and not from global warming as once thought.

It also shows the role geological events have played on our climate, specifically volcanic eruptions.

While the Earth has gone through a number of extinction level events, the one that happened at the Permian-Triassic boundary was one of the deadliest.

Over 95 percent of marine life vanished from the face of the planet.

Scientists previously believed it was from a rise in temperatures that preceded Climate Change, but researchers from the University of Geneva and University of Zurich discovered the die-off arose from a mini ice age.

Dating the past

The researchers worked on layers found at the Nanpanjiang basin in southern China. Bjorn Baresel, a University of Zurich scientist, said they made several cross sections of the basin sediments to determine the exact positions of ash beds in the marine sediments.

Then they dated the sediments using the natural radioactive decay of uranium from the mineral zircon. Because it decays at a specific speed, they can be accurate to within 35,000 years.

    THE EXCITING NEWS FOR CLIMATE CHANGE SCIENTISTS.”

    A new renewable energy discovery on global hydroelectric! For the production of electricity from water, We had methods of (Dams, lagoons power plant and water wave) before. Now we have a new renewable energy discovery on global hydroelectric! It can change the world and start a new industrial revolution in the world.

    THE WORLD’S TOUGHEST SCIENTIFIC QUESTION ON HYDROELECTRIC AND FLUID MECHANICS WERE ANSWERED!
    The KURDESTAN ELECTRICITY is a new renewable energy on hydroelectric with its new formula (Ee>Ep+E1at) = (E>P+1at). Now this new formula added to all renewable energy of hydroelectric in the world.
    DO WE SEE THE GLOBAL ENERGY CHANGE SOON?
    WHAT IS THE REACTION OF THE WORLD TO THIS NEW SCIENTIFIC FORMULA ON HYDROELECTRIC?
    WHAT IS THE REACTION OF THE WORLD TO THIS NEW SCIENTIFIC FORMULA ON HYDROELECTRIC?
    A NEW SCIENTIFIC FORMULA DISCOVERY TO SOLVE THE GLOBAL ENERGY PROBLEM!

    (Ee>Ep+E1at) = (E>P+1at)
    What is the most difficult scientific question of global hydroelectric that no one scientists could the answer to it?
    Now the hard global question!
    How can we produce clean energy in a best way by the potential of water Static head in dams & seas that this water pressure can push to the center of planet?
    Answer:
    This is by getting benefit of joint scientific formula (E>P+1at) with immersion turbines method inside the water of dams & seas (Immersion turbines of series and parallel in zero point of opposite forces).
    Ee= High pressure clean energy that is produced by the water power plants in the depth of water via released fixed potential energy of water natural pressure (More than ten meters of water) with new method (Immersion turbines of series and parallel in zero point of opposite forces).
    Ep= Released fixed potential energy of water natural pressure in water depth (More than ten meters of water).
    E1at= Amount of energy that is consumed at a small pump of one atmosphere power is the ability (In the same place of the water power plant in water depth).
    Many scientists believe that the discovery of the formula is unparalleled. Although many still in shock! How this formula has not be discovered by scientists in the world. Answer to a hard question that scientists are searching for hundreds of years and they can control of climate change and stop global warming soon.
    My new formula and new method can change the world and start a new industrial revolution soon. Note: This new solution and this new formula invention in Iraq and Turkey to formally accepted.
    This invention is patented in Department of Justice in Kurdistan of Iraq No. 952/6 on 12/6/2013.

      Kambiz, how much water by- passes the generators at Niagara Falls and why?

    Hmmmm Kambis… That was really…… interesting…?

    Now for something completely different, and regarding the original post…

    My property in north central Wisconsin is filled with rocks and boulders. I cannot dig a post hole without hitting something t least the size of a grapefruit. Why? These are the remains of a terminal glacial moraine left behind only 11,000 years ago. That is barely a blink of an eye in geologic time. So why is it that this incredible example of recent NATURAL climate change is completely ignored by the eco-left?

    Talk among yourselves…

    Same kind of “field stones” I decorate my yard with here in Ontario. Remnants of an Ice Age created by an asteroid. Do we have the capability to stop an incoming rock? No. What we do have is lots of politicians and Ph.D’s.
