ESA Satellite Shows Sudden Ice Loss In Southern Antarctic Peninsula 268

ddelmonte tips news that the ESA's CryoSat spacecraft has detected a sharp increase in the rate at which ice is being lost in a previously stable section of Antarctica. In 2009, glaciers at the Southern Antarctic Peninsula began rapidly shedding ice into the ocean, at a rate of roughly 60 cubic kilometers per year (abstract). From the ESA's press release: This makes the region one of the largest contributors to sea-level rise in Antarctica, having added about 300 cubic km of water into the ocean in the past six years. Some glaciers along the coastal expanse are currently lowering by as much as four m each year. Prior to 2009, the 750 km-long Southern Antarctic Peninsula showed no signs of change. ... The ice loss in the region is so large that it has even caused small changes in Earth’s gravity field, detected by NASA’s GRACE mission. Climate models show that the sudden change cannot be explained by changes in snowfall or air temperature. Instead, the team attributes the rapid ice loss to warming oceans.

                The system you have is perfectly adequate, it is just that people don't have the required patience to use it. The obvious current flaw is a lack of additional political parties at the federal level. This can be rectified, but would have to take place gradually over the span of many electoral cycles, as most people will subscibe to the "better the devil you know" notion.

            It's not only the politicians but the main stream media that is owned by powerful financial interests. The media is more interested in reporting the horse race and clashes between politicians than they are in substantial reporting on the issues.

            The same thing has happened in a lot of timber towns in Oregon. But in the end things change, the world moves on and people have to accept reality and move on with it rather than clinging to a lifestyle that is no longer viable. Yes, we should assist them with the transition but they need to help themselves as well.

          This. If you know anything about lawyers and law, the first tenet is NEVER ADMIT FAULT. No good can come of it. People might then expect you to pay for damages or whatever.

          Environmentalists make the mistake thinking that conservatives are stupid. That is not the case. The only thing they care about is that they will not have to pay for or be part of the solution. Any time you spend trying to convince them otherwise is wasted.

          The other bit is that politics is never proactive, always reactionary. No environmental protection or anti-pollution law was ever passed until something was already FUBAR, be it due to the London yellow fog, or smog over LA, holes in the ozone layer, or Chinese urban centers shutting down due to respiratory issues. The politicians will maybe finally get around to doing something substantial about AGW after there's a refugee crises from low-lying areas, like the Netherlands, Bangladesh, Louisiana, Florida, etc. Chances are, they still won't blame AGW, since it'll be sea swell from a hurricane/typhoon that does those population centers in, but at some point they'll get tired of throwing money at those places to rebuild. Fortunately there are already a lot of migrant refugee boats in the Mediterranean and Andaman Sea for other reasons, so we're already slowly building a framework for dealing with these kinds of things.

      Apparently, the Antarctic Peninsula is a specific feature. http://en.wikipedia.org/wiki/Antarctic_Peninsula

      Since peninsulas stick out into the ocean and the ocean is (of course) north of antarctica, I assume "Southern Antarctic Peninsula" describes the base of the peninsula, rather than referring to some nebulous "Southern Antarctica", which would be nothing more than an amusing way to refer to the pole. Giving directions there has got to be very confusing. Clocks basically turn east down there.

    • Being as it is the continent that encompasses the south pole, how do you define what is southern?

      Antarctic is a big continent. The Antarctic Peninsula stretches out toward South America. The article specifically talks about the southern Antarctic Peninsula which is well north of the South Pole.

  • Not sure how this is news for nerds. Warming oceans are melting ice. That's not a surprise, it's not something new. We already know the oceans are warming. We already had a pretty good idea that warmer water meant ice would melt. We already know sea level is rising, meaning ice is melting.

    The news part would be if this was unexpected or otherwise faster than expected, which really doesn't seem to be the case, so yawn. I suppose it does open a platform for people to yell catastrophe, denier and other none se

      The earlier submission is not citing NASA's satellite. According to the submission itself, the "original source" is Forbes. The article on Forbes does not have any link to NASA website, he has a link to a graph which shows some data, but does not link to any explanation of this data. (you know, something like a scientific article, or at least the web page of the satellite/project which provide the data, just to know what it represents)

        • And even the graph shows a downward trend.

          For ice trends it's important to note if you are talking Arctic versus Antarctic as well as land versus sea ice. Here's a link for sea ice extent in both Arctic and Antarctic from NASA [nasa.gov]. Shows pretty clear downwards trends in Arctic and upward in Antarctic. Incidentally, the IPCC first report in 1990 estimated warming would reduce Arctic sea ice, but precipitation changes would increase overall ice mass in Antarctic...

      Moreover, the link is to an opinion piece, not a news source. No wonder it was rejected.

      But if you want to talk about the Forbes piece, it claims there is *no* polar sea ice retreat (and the headline is worse, it claims there is no polar ice retreat at all, sea or otherwise). It fails to distinguish between Arctic sea ice
