Non-polar glacial ice holds a wealth of information about past changes in climate, the environment and especially atmospheric composition, such as variations in temperature, atmospheric concentrations of greenhouse gases and emissions of natural aerosols or human - made pollutants... The glaciers therefore hold the memory of former climates and help to predict future environmental changes.

Oeschger and his colleagues in Bern were the first to measure the glacial - interglacial change of atmospheric CO2 in ice cores, showing that atmospheric concentrations of CO2 during the glacial period was 50 % lower than the pre-industrial concentration, a result predicted by Arrhenius nearly a century earlier.

Yuan et al. (LDEO Columbia University), 5.08 (+ / - 0.51), Statistical The prediction is made by statistical models, which are capable to predict Arctic sea ice concentrations at grid points 3 - month in advance with reasonable skills.

A threshold h applied on the (thickness Feb = Mar concentration Sept) field yields the predicted September extent after the regression with the past four years of sea ice extent observations.

Actually most of this will become irrelevant as the predicted shocker is starting http://ocean.dmi.dk/arctic/icecover.uk.php I think the next 6 months will be the definite end of the AGW scam Thanks to S Goddard for emphazising NH ice concentrations.

This is in agreement with the statistical model of Tivy (see June report) that predicts below - normal ice concentrations, comparable to 2009.

This is consistent with both the June and July (Figure 3) ensemble predictions from a coupled ice - ocean model submitted by Zhang, which show considerably more ice in the East Siberian Sea compared to 2009, and it is consistent with the June statistical forecasts submitted by Tivy, which also predict a greater ice area than in 2009 and above - normal ice concentrations along the coasts.

The IPCC 2007 Fourth Assessment of climate change science concluded that large reductions in the emissions of greenhouse gases, principally CO2, are needed soon to slow the increase of atmospheric concentrations, and avoid reaching unacceptable levels.However, climate change is happening even faster than previously estimated; global CO2 emissions since 2000 have been higher than even the highest predictions, Arctic sea ice has been melting at rates much faster than predicted, and the rise in the sea level has become more rapid.

September pan Arctic sea ice extent is calculated from predicted sea ice concentration.

NMEFC of China (Li and Li), 4.02 (3.10 - 4.57), Statistical We predict the September monthly average sea ice extent of Arctic by statistic method and based on monthly sea ice concentration and extent from National Snow and Ice Data Centice extent of Arctic by statistic method and based on monthly sea ice concentration and extent from National Snow and Ice Data Centice concentration and extent from National Snow and Ice Data CentIce Data Center.

The model predicts that large negative sea ice concentration anomalies (< -40 %) will occur in the Beaufort Sea, Chukchi Sea, Laptev Sea, Kara Sea and Barents Sea in September 2016.

In the new study, published today in Environmental Research Letters, researchers from Russia used climate models of sea - ice concentrations to predict what will happen to one optimal trade route along the Northern Sea Route in the future.

Although high concentrations of sea ice still remain in the central section of the passage, Howell predicts that this ice will melt out by September if above normal air temperatures and the rapid rate of decline observed in July persists through August.
