    Also in September, American Craig Loehle, a scientist who conducts computer modelling on global climate change, confirmed his earlier findings that the so-called Medieval Warm Period (MWP) of about 1,000 years ago did in fact exist and was even warmer than 20th-century temperatures.

    Prior to the past decade of climate hysteria and Kyoto hype, the MWP was a given in the scientific community. Several hundred studies of tree rings, lake and ocean floor sediment, ice cores and early written records of weather -- even harvest totals and censuses --confirmed that the period from 800 AD to 1300 AD was unusually warm, particularly in Northern Europe.

    But in order to prove the climate scaremongers' claim that 20th-century warming had been dangerous and unprecedented -- a result of human, not natural factors -- the MWP had to be made to disappear. So studies such as Michael Mann's "hockey stick," in which there is no MWP and global temperatures rise gradually until they jump up in the industrial age, have been adopted by the UN as proof that recent climate change necessitates a reordering of human economies and societies.

    Dr. Loehle's work helps end this deception.

    Oct. 7, 2008 -- Sea ice in the Arctic Ocean has melted to its lowest volume in recorded history, according to new measurements.

    At the end of last summer, the sea's ice pack melted to the lowest coverage ever, following an exceptionally warm winter. But the winter of 2007-2008 was colder than the last few years have been, and even after this summer's melt season there is still more acreage of ice covering the water than last year.

    The problem is, the ice may be thinner than ever.

    Walt Meier of National Snow and Ice Data Center in Colorado and colleagues say the overall ice volume in the Arctic Ocean is at least as low as 2007, they say, and may even have dwindled more by as far as 10 percent. Though more widespread than last year, the ice is significantly thinner, Meier said, making it more prone to melting than ever before.

    Hmmm...


    High retention of first-year ice

    Perhaps the most interesting aspect of the 2008 melt season was the higher-than-average retention of first-year sea ice (see earlier entries, including April 7). Relatively thin first-year ice is more prone to melting out completely than older, thicker ice. However, more of this year’s first-year ice survived the melt season than is typical. Sea ice age maps from Sheldon Drobot, our colleague at the University of Colorado at Boulder, show that much more first-year ice survived in 2008 than in 2007. This is one of the reasons that 2008 did not break last year's record-low minimum.

    One cause of the high first-year ice survival rate was that this summer was cooler than in 2007. Lower temperatures slowed the melt rate in the early part of the season. While conditions in August favored rapid ice loss, they were not enough to make up for this early-season "cushion." Furthermore, much of this year's first-year ice was located at higher latitudes than in 2007, covering even the geographic North Pole. Regions that are far north have lower melt rates because they receive less solar energy than more southerly regions.
    Dispersive sea ice motion

    Sea ice motion also helps determine how the ice will fare each melt season. In 2007, a strong northward sea ice motion at the end of the melt season pushed ice floes together, compacting the ice. The tightly packed ice and high temperatures worked together to create a record-low extent.

    This year, the wind patterns were different, leading to a less compacted ice cover. This, paired with slower summer melt, helped keep the overall extent larger.
