    World is at its hottest since prehistory, say scientists
    By Geoffrey Lean, Environment Editor
    Published: 18 December 2005
    The world is now hotter than at any stage since prehistoric times, a top climatologist announced last week. His startling conclusion comes as Nasa reported that 2005 has been the hottest year ever recorded.

    Dr Michael Coughlan, head of the National Climate Centre at the Australian Government's Bureau of Meteorology, said: "One probably has to go back into prehistoric times - and way back in them - to be seeing these sorts of temperatures."

    Top British climatologists agree privately but are cautious of saying so in public because, naturally, no measurements were taken of temperatures then.

    Dr Coughlan is supported by research that shows carbon dioxide levels in the air - the main cause of global warming - are higher now than at any time in the past hundreds of thousands of years.

    Scientists in Bern, Switzerland, and Oregon in the United States analysed levels of the gas in tiny air bubbles trapped in Antarctic ice during the past 650,000 years. They found current levels were 27 per cent greater than the highest level over that period.

    Professor Sir David King, the Government's Chief Scientist, has said the last time levels of the gas were that high was 60 million years ago. And that was during a period of rapid warming in the Palaeocene epoch, which caused a massive reduction in life on Earth.

    Meanwhile, top climatological bodies around the world report that 2005 is vying with 1998 as the warmest year on record. Nasa says it just beats it, while the Met Office says it is just behind it, and the US government's National Climatic Data Centre says the two years are statistically indistinguishable.

    Whichever is right, 2005 has been a remarkable year, for 1998 was made much hotter by a strong El Niño, the warm Pacific current that strongly affects weather around the globe.

    Last June, September and October were all logged as the warmest ever, world-wide. The past 10 years are all in the warmest 10 ever recorded, apart from 1996 whose place is taken by 1990.

    This year Arctic sea ice dropped to its smallest ever extent, the Atlantic suffered a record hurricane season and an unprecedented drought reduced the flow of the Amazon to its lowest ever level. Canada and Australia had their hottest ever weather this year, while India, Pakistan, Bangladesh and Algeria suffered heatwaves touching 50C.

    Yep, it;s just a normal climatic cycle.

      These studies are just so accurate, too

          Sure looks cyclical

          Be thankful we're on the upslope of the warming cycle and not the downslope after a peak.

            Berz shows is lack of knowledge on the subject by trying to use the glacial-interglacial cycles.

            We HAVE been cooling from the peak of the current interglacial for the past 6000 years. And where do you think that extra CO2 in the air came from in the past 200 years? More CO2 = warmer temperatures, it's right in the graph in your link. Anyone who disagrees with that fact is a MORON.

              And what's so bad about higher temps? Extinction? bah! We get what's coming to us.

              Animals and mammals will adapt, the earth moves on. yadda yadda. Those that cannot adapt will die off. This may or may not include humans.

              I fail to see how global warming is a bad thing. Yes there is the possibility scientists say of runaway greenhouse effect (like Venus). Basically once it starts, temps really go way out of control. As the problem compounds itself. So we destroy an entire planet. Big Deal. It's our planet to destroy.

              But you know what. We live on this planet too. And humans have a right to use it as they may. You don't see animals getting on each other for taking a dump in the woods. But us humans are supposed to bury it. Yeah, yeah that makes us no better than animals. But then people should know this. Humans are animals. Only the religious freaks who think god created us think otherwise.

              to think we can go back to the stone age is ridculous. It's completely ignoring human nature. The genie is out of the bottle. There is no going back to the the pre-industrial age.

                  you like that.

                  Most of that is serious. Not a troll.

                  The liberals want us to reduce our economy to unreasonable levels. Which I think coincides with my guilt theory about liberals. And that they feel guilty being white and having lots of money.

                  To think contries in Africa and China are going to reduce emissions is fallacy. It's a dog eat dog world. And we have to compete, or die off. We just have to deal with nature. It's survival of the fittest. If we let up just a little bit, we're gone just like that.

                      Are these ice core samples from 650,000 years ago or so being retrieved from a single location, or from spots across the planet? If the latter, how can scientists be sure the ice layers are identical (i.e. I'm sure it wasn't deposited evenly, which means you can't drill 60 feet into the ice at each location and expect it to reach the 650,000-year-old layer).

                        Absolute rubbish, these scientists DO NOT KNOW world history. There was a major warm period around 1000AD which allowed the Vikings to thrive as a people and explore right across to and settle in North America. A later cooling resulted in the extinction of those settlements. There is nothing to suggest that todays warming even approaches the warming of those days.
                        Furthermore scientists have shown that the earth warms in the period between major volcanic eruptions and then cools during the eruption. The earth is now overdue for another major eruption and therefore this factor as well as human activity has contributed to the current warming trend.
                        Let the major eruption begin and cool the earth.

                          Nearly all the really deep cores are from the interior of Antarctica. this 650,000 year one is a single ice core, the deepest ever extracted, that last one, going back 400,000 years, was from the same place, IIRC.

                            The Medieval Warm Period and the Litle Ice Age are small compared to the current warming, and affected the North Atlantic region more than the rest of the world. Only massive volcanic eruptions, like Mt. Pinatubo, affect the climate, and then only for a year or two.

                              It's sort of too bad scientists haven't been able to corroborate the core readings from other locations on the planet. Heh. Ice isn't exactly the same as the KT boundary, though. Insofar as I know, there isn't any 65-million-year-old ice in existence.
