New Science Suggests the Ocean Could Rise More -- and Faster -- Than We Thought (washingtonpost.com)

Chris Mooney, writing for the Washington Post: Climate change could lead to sea level rises that are larger, and happen more rapidly, than previously thought, according to a trio of new studies that reflect mounting concerns about the stability of polar ice. In one case, the research suggests that previous high end projections (PDF) for sea level rise by the year 2100 -- a little over three feet -- could be too low, substituting numbers as high as six feet at the extreme if the world continues to burn large volumes of fossil fuels throughout the century (Editor's note: the link could be paywalled). "We have the potential to have much more sea level rise under high emissions scenarios," said Alexander Nauels, a researcher at the University of Melbourne in Australia who led one of the three studies. His work, co-authored with researchers at institutions in Austria, Switzerland, and Germany, was published Thursday in Environmental Research Letters. The results comprise both novel scientific observations -- based on high resolution seafloor imaging techniques that give a new window on past sea level events -- and new modeling techniques based on a better understanding of Antarctic ice. Further reading: Sea levels to rise 1.3m unless coal power ends by 2050, report says (The Guardian).

      Katrina caused less property damage than the hurricane a couple of years later. The big problem with Katrina was that it caused a collapse of a chunk of the insurance industry. Several (six, I think) insurance companies went out of business because they had incorrectly modelled systematic risk: they thought they had a diversified portfolio of risk, but didn't take into account that several of the things that they'd insured against either caused each other or had the same cause. The insurance industry (well, the surviving bits) spent a lot in the following years on improving their models of systemic risk (some of my colleagues worked with them on identifying cybersecurity risks).

      This was compounded in the case of Katrina by the fact that a lot of the affected people were too poor to afford Federal flood insurance the combination of the uninsured and the insured-but-by-a-company-that's-gone-bust a huge number of people (and companies) didn't have the financial ability to rebuild. This was exacerbated by a poor response from both the local and Federal governments.

    Early projections had wide uncertainties, which means that the upper limits based on some projection technique could be quite eye popping. However so far as I know there was never any widely held scientific opinion that there would be a 3m rise by 2020. More typical projections from about 20 years ago were talking about maybe 12 cm against an 1800s baseline, which turn out to be pretty accurate. However the upper range was on the order of 30 cm and the lower showed an actual decline to pre-20th century levels by 2020 -- which goes to show there was still considerable uncertainty.

    Estimates from back in the mid 90s were for a 40cm to 65cm rise by 2100, mainly based on thermal expansion. That's a fairly safe assumption: warmer atmosphere = warmer ocean = more ocean volume.

    Now there have been hypothetical scenarios proposed in which sea level could rise rapidly. Obviously those have not happened ... yet. But as they are based on certain discrete and unpredictable events that they haven't happened is not evidence that they won't happen.

    Pretty much this.

    It's not just wealthy western nations. We're actually making renewable energy sources cheaper than coal and gas--unsubsidized--by sheer technical progress. That's always been the problem: burning fossile fuel might or might not be causing something called "Climate Change"--a point of contention in political discussions--but you can't really do anything about it because making your $THING more-expensive means people get $THING from dirty-coal high-emissions import instead. US becomes poorer by going to Solar 30 years ago, China ramps up production and turns the Asian continent into one giant black cloud.

    We took a third option and just tightened up emissions standards as technology became available to do so without compromising our economy. The Republicans complained, the Democrats took a careful hand, and the really left-wing liberals with no concept of anything just screamed that it wasn't enough. That's the best you can do.

    Well, it was.

    Like you noticed: the really low-emissions energy tech is just plain taking over. It's more viable economically now, and so will come into play without compromising our economy. Leading up to this, we had an offset program where solar generation produced credits which you could sell on the open market in a cap-and-trade scheme; and suddenly solar is so cheap that SRECs trade for $20 instead of $200. A massive amount of capacity sprung up in two years, and more is coming.

    I want to preserve our agricultural land by moving off traditional farm subsidies and onto a scheme where we subsidize farmers to lay non-permanent Solar installation, and reduce the subsidy as the solar installation starts generating a profit. Need the ag land again? Get a crew to unbolt the panels, stack them in a nearby shed, pull up the racks, dismantle, store, and you have ag land. Actually tearing down a city costs more than our GDP; removing a non-fixed solar installation is a cheap job.

    That will save the taxpayer the cost of farm subsidies; protect our agricultural reserve land from permanent destruction by urban development; and derive useful economic productivity from that land area--you know, land area in a place with lots of sun, because a farm is basically a solar food generation operation--instead of just waste expense trying to prevent its development. Because that economic productivity is electricity, it offsets our need for mercury-belching coal plants.

    Leading-edge recouperating CAES--the kind that stores heat and uses it to expand the tanks, not the natural gas booster kind--will become common tech soon enough. It's cheaper than batteries, and hasn't taken off because we keep trying to use natural caves as compression tanks--folks keep selecting sandstone caverns, then finding out that won't work. Going to have to build an actual sealed storage tank underground. Batteries will still be more-expensive, but not 300x more-expensive; even so, hundred-million-dollar-scale R&D tech doesn't just happen at a fast pace, even with those kinds of potential profits, and with the technology pretty much ready-to-go. It's weird to see something that's current-generation technology held back by... well, technology. Paradox.

    Put the two together and you get a bona fide solar grid for basically nothing. I'm so glad there are only 50,000 coal workers in the US, because they're right in the path of progress and a bigger industry would be a recession waiting to happen. We'll bleed the coal mining industry slowly, not overnight; and my Universal Dividend should help hold these people up and rebuild their local economies as we pick them apart.

    The very first IPCC report-- back in 1990--predicted "an average rate of global mean sea level rise of about 6 cm per decade over the next century (with an uncertainty range of 3 – 10 cm per decade), mainly due to thermal expansion of the oceans and the melting of some land ice. The predicted rise is about 20 cm ... by 2030, and 65 cm by the end of the next century."

At the year 2070, the rise is 21-71 cm, with a best-estimate of 44 cm." (page 261) According to NASA satellite data, we are at ~8.5cm since 1990 (and the IPCC AR5 has similar results (SPM page 11)) We have 13 years at (currently) ~3.5mm/year left, so we probably will end up at about 14cm, well within the uncertainty interval, and not far from the best estimate - and very far from the 10 feet you have apparently heard from some crap source.
