Arctic Sea Ice Melting Faster NASA Video

"Everything is trending up -- surface temperature, the atmosphere is warming, and it seems also that the ocean is warming and there is more warm and saline water that makes it into the Arctic," the CBC quoted Kinnard said saying, "and so the sea ice is eroded from below and melting from the top."
Previously, sea ice loss was driven by changes in ocean currents and not necessarily by periods of warmer temperatures.


Current conditions: contribution from melting glaciers

Global sea level is currently rising as a result of both ocean thermal expansion and glacier melt, with each accounting for about half of the observed sea level rise, and each caused by recent increases in global mean temperature. For the period 1961-2003, the observed sea level rise due to thermal expansion was 0.42 millimeters per year and 0.69 millimeters per year due to total glacier melt (small glaciers, ice caps, ice sheets) (IPCC 2007). Between 1993 and 2003, the contribution to sea level rise increased for both sources to 1.60 millimeters per year and 1.19 millimeters per year respectively (IPCC 2007).

Antarctica and Greenland, the world's largest ice sheets, make up the vast majority of the Earth's ice. If these ice sheets melted entirely, sea level would rise by more than 70 meters. However, current estimates indicate that mass balance for the Antarctic ice sheet is in approximate equilibrium and may represent only about 10 percent of the current contribution to sea level rise coming from glaciers. However, some localized areas of the Antarctic have recently shown significant negative balance, e.g., Pine Island and Thwaites Glaciers, and glaciers on the Antarctic Peninsula. There is still much uncertainty about accumulation rates in Antarctica, especially on the East Antarctic Plateau. The Greenland Ice Sheet may be contributing about 30 percent of all glacier melt to rising sea level. Furthermore, recent observations show evidence for increased ice flow rates in some regions of the Greenland Ice Sheet, suggesting that ice dynamics may be a key factor in the response of coastal glaciers and ice sheets to climate change and their role in sea level rise.

In contrast to the polar regions, the network of lower latitude small glaciers and ice caps, although making up only about four percent of the total land ice area or about 760,000 square kilometers, may have provided as much as 60 percent of the total glacier contribution to sea level change since 1990s

Oh this year is gonna get interesting Like my vids sub my page updated every day

[DeepSkyro]

@fudgedogbannana the study has been done over a period of 7 years. Also, it only adds to the fact known from so many other studies that the the ice is dramatically melting

[DeepSkyro]

This guy has an almost apologetic voice :)

This is serious stuff. When addressing the public, you must put the correct level of importance and emotion. Get someone that shouts and swears!

[m1aws]

Since 2007 when strong winds and currents melted the Arctic dramatically, the ice has been rebuilding itself quite nicely. It is now just one standard deviation point below the mean amount.

This man is a liar.

[fudgedogbannana]

If you are just now learning how to measure how thick the sea ice is how do you know its thinner? thinner than what? you just said you didnt know how to measure it before.

[eleutheromaniac]

they show from 2003-08....not exactly a huge sample set for a geological occurance. a 5 year span isn't even an eye-blink. and i have to wonder why they stopped in 2008 when it's 2011 (unless this is an old video). if you just mentally extrapolate the rate of melting according to this video over 5 years, shouldn't the ice caps have been completely melted by now? which clearly isn't the case and there are even reports of expansion in some areas.

This is why they are spraying chemtrails...I think...at least one of the reasons...Why all this in 2009, after Obama came into office, What they don't say is that using haarp and spraying chemical aerosols are causing huge acid clouds that are eating chunks in the ozone...the cure is worse than the illness...NASA is in on Agenda 21...The director was fired after Obama came in..Evidently didnt agree with poisoning the atmosphere...They are causing drought...BASTARDS...

[Anonanoid]

To bad when they make these vids they don't give you the whole truth. What a waste.

[Anonanoid]

@rollsthepaul you are correct sir.
