Among them: ice coverage time - lapse from 1978 - 2006 and 2007's ice retreat (the greatest ever recorded).

Not exact matches

It seems clear to me that that mountain glaciers and permafrost are: 1 sensitive indicators of changes in temperature; 2 uncontaminated by urban heat islands; 3 have short response times (no problem with lagged response to Little Ice Age cooling); have wide geographical coverage (especially in remote areas).

Unfortunately, the tough scientific work to clarify ice and sea trends and dynamics has largely been obscured online by coverage focused on an error on Greenland ice loss that many polar scientists say made it into the new edition of the Times Comprehensive Atlas of the World (that's the British Times, just to be clear).

The marine coring record for the Arctic suggests that the Artic has never been (summer time) ice free for at least hundreds of millions of years; you'll have to find the papers and look at the extent of coverage yourself.

The problem with this obsessive focusing on one single data point out of 365, is that there is a lot of short term, weather driven variability that can affect the exact timing and size of the minimum in ice coverage.

«The time of occurrence of the maximum and minimum sea ice coverage in the Arctic showed slight trends towards occurring earlier in the year, although not significant.

BBC News reports that data from Europe's Cryosat spacecraft shows that Arctic sea ice coverage was nearly 9,000 cubic kilometers (2,100 cubic miles) by the end of this year's melting season, up from about 6,000 cubic kilometers (1,400 cubic miles) during the same time last year.

If the previous melt was localised around Spitzbergen, why hasn't he offered any evidence of extensive ice coverage elsewhere at the time?

Based on results of a simple model that keeps track of the age of ice as it moves about on the Arctic Ocean, we argue that the areal coverage of thick multi-year ice decreased precipitously during 1989 - 1990 when the Arctic Oscillation was in an extreme «high index» state, and has remained low since that time.

Meanwhile, 6,000 kilometers to the north, the Arctic has less sea ice than at any time in the 37 years that satellites have been measuring ice coverage.

The timing of ice advance and retreat and the extent of coverage vary greatly from year to year.

This year, as has been true since 1979, that sea ice coverage is abundant across the Arctic for seals that are giving birth and mating at this time as well as for polar bears busy feeding on young seals and mating.

CMIS represented the state of the art in satellite microwave radiometers and was intended to continue, with a higher degree of accuracy and resolution, the time series of many fundamental climate variables, including SST and wind, sea ice and snow coverage, soil moisture, and atmospheric moisture (vapor, clouds, and rain).

Despite its areas of inaccuracy, near - real - time data are still useful for assessing changes in sea ice coverage, particularly when averaged over an entire month.

Secondly, the weather which is present in Colorado Springs certain times of the year, such as snow and ice, makes having good auto insurance coverage a must.
