Ice core The length of the record depends on the depth of the ice core and varies from a few years up to 800 kyr (800,000 years) for the EPICA core. The time resolution (i.e. the shortest time period which can be accurately distinguished) depends on the amount of annual snowfall, and reduces with depth as the ice compacts under the weight of layers accumulating on top of it. Upper layers of ice in a core correspond to a single year or sometimes a single season. Deeper into the ice the layers thin and annual layers become indistinguishable. An ice core from the right site can be used to reconstruct an uninterrupted and detailed climate record extending over hundreds of thousands of years, providing information on a wide variety of aspects of climate at each point in time.

Scientists debate polar sea-ice opposites 22 September 2014Last updated at 16:14 ET By Jonathan Amos Science correspondent, BBC News Explanations for the Antarctic abound, but there is "no single, underlying, silver-bullet cause" Arctic sea ice has passed its minimum summer extent, say polar experts meeting in London. The cover on 17 September dipped to 5.01 million sq km, and has risen slightly since then, suggesting the autumn re-freeze has now taken hold. This year's minimum is fractionally smaller than last year (5.10 million sq km), making summer 2014 the sixth lowest in the modern satellite record. The Antarctic, in contrast, continues its winter growth. It is still a few weeks away from reaching its maximum, which will continue the record-setting trend of recent years. Ice extent surrounding the White Continent has just topped 20 million sq km. The marine cover at both poles is the subject of discussion at a major UK Royal Society conference taking place this week. 'Normal year' The regions' geographies are quite different.

Weather Online - current weather and forecasts worldwide Isotope The three naturally-occurring isotopes of hydrogen. The fact that each isotope has one proton makes them all variants of hydrogen: the identity of the isotope is given by the number of neutrons. From left to right, the isotopes are protium (1H) with zero neutrons, deuterium (2H) with one neutron, and tritium (3H) with two neutrons. Isotopes are variants of a particular chemical element such that, while all isotopes of a given element have the same number of protons in each atom, they differ in neutron number. The term isotope is formed from the Greek roots isos (ἴσος "equal") and topos (τόπος "place"), meaning "the same place". Thus, different isotopes of a single element occupy the same position on the periodic table. For example, carbon-12, carbon-13 and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13 and 14 respectively.

Antarctic sea ice set for record high as Arctic heads for sixth lowest extent | Environment The extent of sea ice in Antarctica is set to reach a record high, scientists said on Tuesday, as they announced that Arctic sea ice appeared to have shrunk to its sixth lowest level ever. The NSIDC said that satellite data was expected to shortly confirm whether the maximum extent of sea ice at the opposite pole, in Antarctica, had set a new record. “Antarctic sea ice is poised to set a record maximum this year, now at 19.7 million sq km (7.6m sq m) and continuing to increase,” the centre, considered one of the world’s top authorities on sea ice data, said in a statement. Jan Lieser, of the Antarctic Climate and Ecosystems Co-operative Research Centre (CRC), told Australia’s ABC News that: “This is an area covered by sea ice which we’ve never seen from space before.” However, the centre noted that there had been a particularly strong retreat of sea ice in the Laptev Sea and although the reasons for that were not yet clear, sea temperatures there had been up to 5C higher than average.
