BBC – CO2 climate sensitivity ‘overestimated’

Global temperatures could be less sensitive to changing atmospheric carbon dioxide (CO2) levels than previously thought, says a new study just published in Science.

“The researchers said people should still expect to see “drastic changes” in climate worldwide, but that the risk was a little less imminent,” says science reporter Jennifer Carpenter, writing about the new study.

“Previous climate models have tended to used meteorological measurements from the past 150 years to estimate the climate’s sensitivity to rising CO2.

Can you believe that we’ve been wasting billions upon billions of dollars based on measurements that go back only 150 years?

“Lead author Andreas Schmittner from Oregon State University, US, explained that by looking at surface temperatures during the most recent ice age – 21,000 years ago – when humans were having no impact on global temperatures, he, and his colleagues show that this period was not as cold as previous estimates suggest.

“This implies that the effect of CO2 on climate is less than previously thought,” he explained.

“To induce large-scale warming of the planet, leading to widespread catastrophic consequences, we would have to increase CO2 more than we are going to do in the near future, explained palaeoclimatologist Antoni Rosell-Mele from the Autonomous University of Barcelona, a member of the team that came up with the new estimates.”

Needless to say, other scientists question that perspective.

  1. Only going back 150 years? That is a flyspeck of time speaking in geologic terms. Many, many researchers have proven time and time again that the earth has had higher C02 levels than today many times in the past. They have proven that the earth did not go through catastrophic changes and runaway warming with higher C02 levels, so why all the panic? Because the global warming myth was a money making scam/fraud from the get-go! And the sheeple believed and bought into it with no real science ever being provided. The sheeple freely opened their wallets and handed over trillions of their hard earned money to the scammers. All that money. How do the sheeple feel now that the earth is cooling after only a few decades of mild warming due to the SUN? For those sheeple; The earth is now cooling because the SUN is cooling! Puny man has no ability to change earth’s temperature. Only the sun can do that.

    • An “honorable” way out, or just trying to save face? There is NOTHING “honorable” about people who will LIE for money, fame, or game while people are robbed or die as a result of the deceit.

  2. Whether or not CO2 is capable of causing “global warming” is almost insignificant.

    What is significant is that life survived periods when the temperature of the Earth was much higher then today or the “devastating” up to 6 degrees the alarmists predict.

    It is generally agreed that the Earth was about 12 degrees warmer during the dinosaurs time – there was probably no ice on Earth at all. At this time it is also believed mammals and birds were evolving.

    There is no doubt that surviving the COLD is the biggest challenge to life.

    It is also bl

  3. Its good to see some truth finally getting printed in the usual fear and hype media, however…they can’t quite let inciting fear for money and mileage go as evidenced by every report disproving the AGW lies being added onto with a “theres still catastrophes likely to occure due to…”
    like a dog with a well gnawed marrowless bone, they still wont let it go.

  4. Probably the atmosphere-lithosphere system behaves as a buffer system. Increasing the availability of CO2 increases the rate and extent of alteration of the rocks absorbing it as, for example, the limestones.

  5. “Gee Wally, ‘This implies that the effect of CO2 on climate is less than previously thought,’”

    “Yeah Beaver, Ya Think?”
