'Unprecedented,' 'Amazing,' 'Goliath': Scientists Describe Arctic Sea Ice Melt


'Unprecedented,' 'Amazing,' 'Goliath': Scientists Describe Arctic Sea Ice Melt
Arctic Sea ice levels continue to drop below record set on Aug. 26


Weather Underground co-founder Dr. Jeff Masters writes that "Every major scientific institution that tracks Arctic sea ice agrees that new records for low ice area, extent, and volume have been set. These organizations include the University of Washington Polar Science Center (a new record for low ice volume), the Nansen Environmental & Remote Sensing Center in Norway, and the University of Illinois Cryosphere Today."

The National Snow and Ice Data Center illustrates the melt since 1979 in the graph below, showing a decline in the ice extent at 10.2% per decade:

Masters adds that the Arctic melt level record might go back even further. "Satellite records of sea ice extent date back to 1979, though a 2011 study by Kinnard et al. shows that the Arctic hasn't seen a melt like this for at least 1,450 years," writes Masters.

Another scientist with the Norwegian Polar Institute engaged in Arctic research, Dr. Edmond Hansen, confirms the historic levels of the ice melt, and tells the BBC it is "amazing."

"As a scientist, I know that this is unprecedented in at least as much as 1,500 years. It is truly amazing -- it is a huge dramatic change in the system."

"This is not some short-lived phenomenon -- this is an ongoing trend. You lose more and more ice and it is accelerating -- you can just look at the graphs, the observations, and you can see what's happening," Hansen said.

Masters notes that the ice melt has real impacts on the climate, since the white snow and ice reflect sunlight while the ocean absorbs it. As the ice melts and we have more sea, we create "a recipe for more and faster global warming," writes Masters.

Until the climate stabilizes at a new state of balance.

My question is this. What part of the biosphere survives the new state? We may all end up living in Canada. Although I wouldn't blame them if they decided that they won't have us, eh?

and no matter what we try to say to her about global warming, she is convinced that it doesn't exist. Not that she doesn't see the current trends of the earth getting warmer. She believes that this is simply cyclical and that this isn't the first time it has happened, and not the worst time it has happened. She doesn't see that this is probably the worst it's been and will continue to get worse still.

It's like telling those who believed the earth was flat, that no, really it's round. You only confuse them with facts.

Tell her bird patterns are changing and migratory birds are migrating south later or not at all.

Tell her that spring comes earlier and fall later and insect infestations are greater. Droughts are deeper and more frequent.

Tell her that summer nights (and days) are getting hotter.

Tell her food prices are going higher at a faster rate than in recent decades.

There are many other examples that can be tailored to her particular interests and hobbies and foibles.

as my husband, his brother & wife have all tried to 'educate' her and her husband. In fact, her husband is a geologist, so he of all people should be more apt than others, to accept these truths! She just saw the movie 2016, and loved it. Ate up all the crap it spewed, and she hates Obama. She is one of those far-right tea-baggers, whose mind is as full as they want it to be, of nonsense and lies.

It's peculiar how people can create a consiracy that requires physical scientists to participate on the side of a socialist conspiracy. They are often pretty apolitical people.

As long as we're here, there is hope. What we are seeing is potentially a disaster that could overwhelm all of humanity, destroy the world as we know it. It is also though... I think possible, that we might discover a solution, or many solutions that, when used together, enable us to survive. I don't know whether it's too late to prevent the ultimate worst case scenario by improving environmental standards and regulations... but we are making progress there - not as much as we need to, but progress nonetheless.

We are a species capable of great things as well as terrible ones. We've put humanity on the moon, we've left behind the Monarchies and Empires of the past. We have overcome tyrants who threatened the overwhelming destruction of all that we hold sacred.

We haven't lost yet.
