Study: Rate of warming over the past century highly unusual but not unprecedented in context of natural climate variability

The researchers analysed a 364-metre long ice core drilled from James Ross Island, off the northern tip of the Antarctic Peninsula, near where the massive Larsen B ice shelf disintegrated in early 2002.

  1. Media reports point out the last 600 years of warming, but ignore the first 400 years of the record. Wonder why?

  2. In case you haven’t noticed there are no more great forests and grass lands that used to cover this world.
    They would have been here to help to balance the effects of our rise in CO2 which we, with out any doubt have been spewing into the atmosphere.
    Only an idiot that makings believe he’s a scientist would forget that we have scaped the lands clean and poisoned the environment like we have.
    Do you work for Exxon/Mobil or BP or Big Coal? Only they would try to pass this off as science…
    It was once said that, “A squirrel could go from tree to tree from the Atlantic Ocean to the Mississippi River without touching the ground”.
    80% of the tree’s mass comes from CO2.
    You are no scientist just scill for the energy conglomerates…
    You are a junk scientist don’cha know…

  3. and it was once said that you should remain silent and let folks think you are a fool rather than to speak up and prove it.

  4. So climate is variable, warmth is variable, and the rate of change in warmth is variable. Who’d a thunk that about a muti-variant coupled non-linear system?
    zagozana, plant cover changes over time with or without human intervention. Humans have replaced areas of vegation with cities and we’ve changed vegetation in some areas. We’ve also nurtured forests and wild areas. There’s no good way to evaluate how those changes may have affected local weather or CO2 exchange.
    Humans have indeed put dangerous items in the environment. And wealthy societies, not poor ones, have worked to remove them.

  5. So, when did all these forests disappear? here’s a clue: well before evil mankind happened upon the scene. Desertification is largely a result of plate techtonics, and unless those big bad oil “scills” are moving the continents around your point is pure idiocy.

    Here’s an idea: make a big sign and stand in the middle of the freeway to get folk’s attention.

  6. Explain how the great forest disappeared, please! Was it the mammoths? The bison? The bark beetles? No, it was and is us…
    By nurturing forest do you mean clear cutting, because that’s what is going on now all over the world.
    GOOGLE… Image search…
    “CLEAR CUTTING”.
    “DESERTIFICATION”
    “ARCTIC ICE CAP MELTING”
    “WHAT STUPID PEOPLE LOOK LIKE”
    THE EARTH IS MORE THAN 6,000 yrs. old….
    DROPPED OUT OF HOME SCHOOL, HUH? You failed obviously.
    Use the internet to find out what scientists say not what Rush “the magic” lint ball says. He’s payed to toe the line, not tell the truth.
    Go look up images of the plastic that covers large areas of the Pacific.

  7. “A squirrel could go from tree to tree from the Atlantic Ocean to the Mississippi River without touching the ground.”

    What a terrible loss we have suffered.

  8. What a tragic loss we are continuing to suffer.
    Having and continuing to promote ignorance of our effects on the world is the most dangerous thing we do.

  9. Listen Sting, if you are going to insult someone’s intelligence please learn to spell, write in complete sentences, post html links, and lay off the caps lock.

  10. so, back on track, what do ANY of these links have to do with the subject of the thread? (Hint: Nothing) Deforestation by clear cutting is a different matter and was not caused by AGW.

    Humans, yes; AGW, no.

    Serious, yes; the subject of this thread, no.

    All you’ve done is hijack a thread and attempted to turn it into a diatribe against clear cutting. For us to pay attention to you you will need to learn to play well with others and stick to the subject of the thread. Otherwise folks will tend to just dismiss you as some sort of foaming ecoflake. And you might want to expand your research, 12 (?) references to the same exact publication is hardly compelling…..
