Major Climate Change 5,200 Years Ago Could Repeat

An anonymous reader writes "The climate was altered suddenly some 5,200 years ago with severe impacts. Famouse glaciologist professor Lonnie Thompson have found clues that show history repeating itself. Thompson has spent his career trekking to the far corners of the world to find remote ice fields and then bring back cores drilled from their centers. Within those cores are the records of ancient climate from across the globe. He outlined his fears today at the annual meeting of the American Geophysical Union in San Francisco. 'The evidence clearly points back to this point in history and to some event that occurred. It also points to similar changes occurring in today's climate as well,' he said."

    What do you think "global warming" is if not "climate change?"

    It's semantics. The present administration refuses to call it "global warming," that's all. Not saying they have a plan or anything - but they do talk about it from time to time. They just don't want to use that "warming" word because it pisses off george's oil buddies.

    And the reason you think this, in spite of the evidence gathered by thousands of scientists and decades of research published in reputable peer-reviewed journals is... what, exactly?

    This is completely incorrect. It's just > WRONG. Human CO2 emissions are many, many times larger than the largest volcanic eruptions. I don't know where you think you're getting your information from...

    You're so badly misinformed it hurts. Go get yourself a hot steaming cup of clue:

    and there are thousands of scientists who have signed a petition stating that the evidence for global warming is not convincing. More research and less "oh my gosh! we are bad bad bad people who will kill everything! Hug trees! Hug trees! Love mother earth" crap needs to be done. Yes we are dumping a lot of CO2 and other crap into the atmosphere, water, land and while I would expect it to have some kind of consequence that doesn't mean it is nearly as bad as some scientists are claiming it will be.

    BLASPHEMER! How dare you pervert the WORD OF GOD with your "close enough" apotheosis! These dirty mundane "scientists" are obviously plagarizing the HOLY BIBLE's story of THE FLOOD, and you are helping them DESTROY CHILDRENS' SOULS by supporting their lies. We will use you as kindling when we burn them at the stake. We'll pick you up after church Sunday - be ready, and wear something flammable.

    Bush agrees that climate change is underway. He believes that this study proves the biblical flood, and he is bringing around the prophecied Apocalpse. It justifies everything he's doing. He's the false messiah: the antichrist.

  6. DDT by datacaliber · · Score: 0, Flamebait

    In regions plagued with malaria, there is an inverse relationship between the amount of DDT used and the number of deaths attributed to malaria. So this basically leaves you two options:

    1) Unban DDT and save countless lives.
    2) Keep preasuring developing nations into banning DDT and bear the burden of thousands of lives.

    I'm not saying that DDT is a perfectly harmless substance, however, I am saying that it's hypocritical and asinine to believe that it should be banned at the cost of human life. There is nothing that we as human do that does not adversely impact the enviroment. Every enviromentalist that I've known drives a car, walks on sidewalks, uses air conditioning, enjoys public lighting, has a house, etc. Am I saying you should give up those luxuries? No! But I am saying that you are a complete ass to think that others should give up things like DDT, which are essential to LIFE, just to ease your "green conscience". There's a reason that no one really takes enviromentalists serious anymore. They get so wrapped up in their "issues" that they are blind to their own hypocricy and the cost of human life.
