Sentences with phrase «ice at it lowest point»

Anthony can hold the stakes, «ice - free» to be defined as less than a million square kilometres of ice at the lowest point.

We wound up with 9 % more ice at the low point than in 2007 — evidence that supports an injection of warm water into the Arctic Basin had melted ice from below and that the 2007 melt was anomalous.

The final image in the series, shown above, shows the sea ice at it lowest point so far this season.

Thinking outside the cup, Rosati Ice pioneered the two - quart Party Pail which provides larger quantities of product at a lower price point for the consumer and a higher margin for the stores.

«If there were a link, it would be more likely to occur in fall [when the Arctic sea ice is at a low and the region is warm] than it would in January [when the Arctic is ice - covered and cold], so from that point of view, it's not a compelling candidate at this time of year,» Hoerling said.

Also in the mid-1990s, another group of scientists proposed the now widely accepted mechanism for how lakes can form under glaciers: Heat radiating from Earth's interior is trapped under the thick, insulating ice sheet, and pressure from the weight of all the ice above it lowers the melting point of the ice at the bottom.

The salt dissolves in the water, lowering its freezing point, which will only turn to ice at temperatures well below 0 degrees C.

Current ice extent is well below levels at the same point in 2012, which went on to set the current record for the lowest sea ice minimum extent:

«Eventually we'll move to a business of lower priced [NOOK] at higher volume» he explained, as well as confirming that plans to sell off the NOOK division — which Microsoft was tipped to be interested in buying at one point — had been put on ice for the moment, while the segment recovers.

The point here isn't that anybody can prove that there has never been this extent of Greenland melting at some prior time in the Holocene, but that all of these indicators taken together (Arctic temperatures, low sea ice extent in summer * and * winter, permafrost melting, decreased snow cover, Greenland melting) indicate that the Arctic as a whole really is warming in an exceptional way.

For example, if the Earth got cold enough, the encroachment of snow and ice toward low latitudes (where they have more sunlight to reflect per unit area), depending on the meridional temperature gradient, could become a runaway feedback — any little forcing that causes some cooling will cause an expansion of snow and ice toward lower latitudes sufficient to cause so much cooling that the process never reaches a new equilibrium — until the snow and ice reach the equator from both sides, at which point there is no more area for snow and ice to expand into.

In this regard, I would observe that at least one important AGW effect, rising sea level, does not depend on a specific regional outcome so much as on global mean T. (At least, I think this is so (because my understanding is that most of the rise comes from lower density of warmer water, not from melting ice sheets — though again, not 100 % sure on this point)-RRBat least one important AGW effect, rising sea level, does not depend on a specific regional outcome so much as on global mean T.

ScienceDaily (Oct. 3, 2008)-- Arctic sea ice extent during the 2008 melt season dropped to the second - lowest level since satellite measurements began in 1979, reaching the lowest point in its annual cycle of melt and growth on Sept. 14, according to researchers at the University of Colorado at Boulder's National Snow and Ice Data Center.&raqice extent during the 2008 melt season dropped to the second - lowest level since satellite measurements began in 1979, reaching the lowest point in its annual cycle of melt and growth on Sept. 14, according to researchers at the University of Colorado at Boulder's National Snow and Ice Data Center.&raqIce Data Center.»

The actual «Wiki» answer is here:» Oranges are sensitive to frost, and a common treatment to prevent frost damage when sub-freezing temperatures are expected, is to spray the trees with water, since as long as unfrozen water is turning to ice on the trees» branches, the ice that has formed stays just at the freezing point, giving protection even if air temperatures have dropped far lower.

(In fact, usually the opposite happens: the higher the minimum point is (the more ice there is at mid-Sept), the lower the mid-winter point is.

please read Z. Jaworowski's (with Segalstad and Ono) many papers on this subject of trapped gases in glaciers, where he discusses the over 20 mechanical and chemical processes that make accurate measurements impossible; even in shallow cores above the point where co2 is supposedly permanently trap in ice cavities in the firn, co2 concentrations are already 20 - 40 % lower than those measured in air at mauna loa.

So it is apparently of no relevance that the maximum ice level tops out at a much lower point than it did in the past?

At this point, the sea ice loss showed more of a historical loss trend, but because of the low June value it has remained below the previous lowest value from 2007.

Without the increased water movement due to the storm, there would be a tendency for the meltwater to stay at the surface due to its relatively low density, which would prevent saltier water (with its depressed freezing point) from coming in contact with the ice.

At low points — ice sheet growth become a runaway feedback leading to glacials.

But the low measurement of sea ice that Carrington pointed to disagreed with at least five other continuous measurements of the Arctic, and was thus unreliable.

Glacials happen when the 100,000 year Milankovitch orbital cycle is such that summer irradiance in high northern latitudes is at its lowest point — allowing the persistence of ice fields.

Apologies if this has already been stated, but my view on decreased Arctic ice cover is: - 1, as Judith pointed out, when ice is at a minimum the sun is already so low in the sky that there is no noticeable change to albedo, 2 when there is ice cover warm water is kept at depth by differences in salinity, When there is open water, storms mix the haline layers bringing warm water to the surface where it can more readily radiate it's energy into outer space.

Arctic sea ice extent in September, the seasonal low point in the annual cycle, has been declining at a rate of 13.4 percent per decade.

Stoat points to the graph of Arctic sea ice anomaly which is lagging behind last years, however it is clear that this year will at a minimum be the second lowest year, if not the lowest.

At this point the critice will say, that this frozen ice ball will reflect 80 % of the sunlight back out into space, so the Temperature would go much lower.
