Global warming trend unparalleled in past 11,000 years

HERE‘s the latest on an issue to which not nearly enough attention is paid by government and industry:

A new study looking at 11,000 years of climate temperatures shows the world in the middle of a dramatic U-turn, lurching from near-record cooling to a heat spike.

Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures back to the end of the last ice age. It shows how the globe for several thousands of years was cooling until an unprecedented reversal in the 20th century.

Scientists say it is further evidence that modern-day global warming isn’t natural, but the result of rising carbon dioxide emissions that have rapidly grown since the Industrial Revolution began roughly 250 years ago.

The decade of 1900 to 1910 was one of the coolest in the past 11,300 years — cooler than 95 percent of the other years, the marine fossil data suggest. Yet 100 years later, the decade of 2000 to 2010 was one of the warmest, said study lead author Shaun Marcott of Oregon State University. Global thermometer records only go back to 1880, and those show the last decade was the hottest for this more recent time period.

“In 100 years, we’ve gone from the cold end of the spectrum to the warm end of the spectrum,” Marcott said. “We’ve never seen something this rapid. Even in the ice age the global temperature never changed this quickly.”

UPDATE: There’s another interesting take on this matter HERE:

[T]he Earth should be nearing the bottom of a several-thousand year cool-off…Instead, temperatures are rising rapidly.

    There must be the following change for any permanent solution.
    New affordable substitutes for fossil fuels.
    New manufacturing processes to replace ones that produce emissions of CO2 and other pollutants.
    Emissions caps accepted by industry.
    Consumer demand for all the above — nothing happens without it.

    “Consumer demand for all the above — nothing happens without it.”

    shawnnews nails it.

  3. Of course, another way to put this is that current temperatures are colder
    than 28% of the Holocene. According to this research the temperatures seen
    in the 20th century were about average for the Holocene.
