Sentences with phrase «melting point in summer»

It requires ≈ 5 °C of local warming for surface atmospheric temperatures to exceed the melting point in summer on the major (Ross and Fischner - Ronne) ice shelves (12, 37).

Not exact matches

This recipe takes advantage of the high melting point of cocoa butter, which makes this body butter more stable in the summer heat.

When it's cold, the deodorant will be harder, but coconut oil has a melting point of ~ 80 F, so when it gets hot in the summer, it'll be a little goopier (and easier to put on).

Cocoa butter has a low melting point, and the wafers often melt in transit to higher temperature states during the summer.

In post # 40, CobblyWorlds points to a recent analysis by Perovich et al. (2008), which uses calculations of solar energy input to the Arctic Ocean to assess the melting last summer.

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.

This ice sheet is losing mass at a rather larger rate (around 220 cubic kilometres per year) and it will take only another 1 - 2 oC world warming to raise the summer melt zone to the top of the Greenland ice pack after which point, in my understanding, the ice sheet will go into irreversible melt.

Is there a discernible point, maybe in a model, that includes reduced albedo in the summer, that might show an acceleration of melting above the average temperature increase curve for the region so that ocean warmth has an increasing role over atmospheric??

The Greenland ice sheet is poised for another record melt this year, and is approaching a «tipping point» into a new and more dangerous melt regime in which the summer melt area covers the entire land mass, according to new findings from polar researchers.

This year, as every year, there has been much excitement in the media about «catastrophic» melting of Arctic sea - ice, run - away melting, tipping points, death spirals and «ice - free» summers.

Except for 2012 (monster winter cyclone storm broke up the ice pushing it into warmer waters — NASA concurs), 2007 marked a turning point — a reversal in the long downward trend of the summer melt season.

Many respondents point to initial conditions for 2008: less multiyear sea ice in March 2008 compared to 2007, a potentially faster rate of melting in summer in 2008.

As I have pointed out in the «essay», what has happened (in an accelerating manner since 1246 CE) is that the insolation reaching far northern latitudes has increased during the first half of each year, and this should be anticipated to cause earlier and more - extensive spring melting of snow and ice, and therefore a progressively - earlier albedo reduction, and therefore more sunlight subsequently being absorbed across spring and summer: the ice albedo feedback effect acting positively (causing warming).

Today, he said, summer temperatures approach or just exceed freezing point around Antarctica: «It would not take much warming to see a pretty dramatic increase [in surface melting] and it would happen very quickly.»

The role of supraglacial lakes in this has been a point of emphasis; Luthje et al, (2006) noted that the area covered by supraglacial lakes was independent of the summer melt rate, but controlled by topography.

To the basic point of the post - what is it that is bad about the arctic being more melted in the summer?
