In Progress: Fastest Sea Rise In At Least 2800 Years (www.cbc.ca)
Layzej writes: A new study finds that sea levels on Earth are rising several times faster than they have in the past 2,800 years and are accelerating. Co-author Stefan Rahmstorf explains that the fact that the rise in the 20th century is so large is a logical physical consequence of man-made global warming. This is melting continental ice and thus adds extra water to the oceans. In addition, as the sea water warms up it expands. The data from the past can also be used for future projections, using a so-called semi-empirical model calibrated with the historically observed relationship between temperature and sea level. With the new data, this results in a projected increase in the 21st century of 24-131 cm, depending on our emissions and thus on the extent of global warming.
All those people buying and living in coastal houses don't seem to believe in climate change I guess. The ocean is rising, yet prices remain sky high for anything near the coast...
Yes it's an anecdote! Were you expecting original research in a Slashdot comment?

They could only examine data for the last 3000 years, and the last 200 years of that were inconclusive. It seems that this means the data is less exact the further back in time you look, which is not surprising. And while the sea level has risen and fallen in the past, it was over a much longer time scale.
What is alarming knowledgeable people now is that the rate the sea level is increasing indicates that this phenomenon is influenced by man, and that it is going to cause severe problems in some number of years. How big or small that number is, and what can we do to influence it favorably are really the only things left to debate, unless you're going to cherry pick the set of science and facts that you're willing to believe.
Pretty much this. And, moreover, the universe doesn't give a crap about our continued existence, and won't take any special steps to save us.
The problem is we're an exceedingly short-sighted species, and the near term profits of corporations are pretty much driving this process, and they'd rather have big executive bonuses now than give a fuck if there's a habitable planet down the road.
I figure the only people actively denying climate change stand to make money from the status quo. Pretending it's not happening pretty much has no rational basis in anything else, because it doesn't otherwise benefit anybody.
Lost at C:>. Found at C.
this research was actually completed during the Harper Regime in Canada, but was intentionally silenced until now.
It is as bad as people have been telling you.
Oh, and if you're a billionaire, you could snap up all the coal firms in the world right now for $150 million and just sit on the coal, because we need to keep all fossil fuels in the ground, unless you want your waterfront home to be underwater.
Cheap, really.

Skeptics should buy up flat beach-front properties if they truly think it's a hoax.
If it is a hoax, the land value will go back up when the hoax is exposed and they'll be jillionaires. If it's not a hoax, the fools get what they deserve.
Table-ized A.I.
Yeah, about that...

You are welcome on my lawn.
Uh, if they drowned, then that'd be ironclad proof that it ISN'T nonsense.
Gotta love that denialist LOLgic.
Exactly. My original comment wasn't naysaying, it was responding to the actuary tables.
When the actuaries say it isn't a good business, then we should be *very* worried. The government support of their communities balances their existence and economic activity against the cost of rebuilding - even though the rebuilding won't last.
What's funny is that this is *Slashdot* -- where I actually come here for the comments, usually because Slashdot is inhabited by geeks, techs, programmers, scientists; i.e; People that should know a thing or two. Usually the discourse here is insightful and thought-provoking...
And then comes a global warming post, and all the science deniers come out of the woodwork. You see posts as dumb as "It's snowing right now out my window -- global warming is a myth!"
This is directed to all the deniers -- what are you people *doing* here on Slashdot? Do you actually work in the technology field and yet deny actual science?
We *KNOW* there's too much CO2 in the atmosphere and we KNOW that it traps heat, so, what precisely are you denying?
Or has Fox News tainted your perception of the world so thoroughly that when something comes up that clashes with your ideology you stick your fingers in your ears and scream "LALALALAL I can't HEAR you!" when presented with FACTS?
Seriously, I don't understand why someone who denies science is on Slashdot -- why not also talk about how Black Holes are a myth, why we can't go beyond a 4Ghz CPU speed because God says so, and solving complex math is forbidden by the Bible? Maybe you'd prefer Slashdot articles on Ghosts, Chemtrails, UFOs and Bigfoot?

Maybe it's this. Salt water remains liquid at lower temperatures than fresh water. So the melted ice water could still be warmer than the ocean it's pouring into.
From TFS:
You might think so. But seawater freezes at a lower temperature than freshwater ice, so, no, the seawater can be liquid while the ice is solid despite the fact that they are both at the same temperature.
and so the net effect would be to reduce the temperature of the water it hits.
Almost right. Added cold water would cool down warmer seawater. On the other hand, the warmer seawater will heat up the added cold water. Since they are at almost the same temperature to start with, the net effect cancels out, and what you get is simply the added volume of the added water.
Not saying the seas aren't warming from other factors, but it seems counter-intuitive to assume that adding glacial / ice meltwater would be a factor for sea temperature increase.
The thermal expansion due to warming and the added glacial melt water are two different effects. The warming isn't due to the added glacial meltwater. The warming occurs globally, even at places thousands of miles away from glaciers. Even if glaciers didn't melt at all, warming would still cause thermal expansion.

It is found that the total global arable land area is likely to decrease by 0.8–1.7% under scenario A1B and increase by 2.0–4.4% under scenario B1. Regions characterized by relatively high latitudes such as Russia, China and the US may expect an increase of total arable land by 37–67%, 22–36% and 4–17%, respectively, while tropical and sub-tropical regions may suffer different levels of lost arable land. For example, South America may lose 1–21% of its arable land area, Africa 1–18%, Europe 11–17%, and India 2–4%. - http://iopscience.iop.org/arti...
This is awesome news. A bigger ocean means more room for fish and assorted sea creatures.
You will notice a large increase over the period. Satellites measure the troposphere though. That isn't really what sea level responds to. Take a look at ocean heat content over the period: https://www.nodc.noaa.gov/OC5/... .
It doesn't mix, it "caps" the warmer sea water and totally jacks with ocean currents. The system and the science is very complex; the freshwater can also lead to ocean acidification and dead zones.
They're always peeing in the ocean!
You say that, but it's like a 100 year lease. While 100 years might seem a lot, you'll notice when your $100,000 lease is only worth $80,000 in 20 years, instead of $150,000 like most property going up in value.
Two have said what you said. It is retreaded 1970s Chicken Little warnings. A religious warning,"But what if we go to hell?!?!?"
In an economically free society, advancement keeps ahead of any downsides. This is the counterintuitive result of Julian Simon's theory that made successful predictions, destroying the 1970s precursor predictions of your statements.
Actual measurements show you are, and will be, wrong. The measurements: actual well being, like calories per person. The context, N vs. S Korea i.e. economically controlled vs. free.
I throw in the bit about today less able to predict 2100 tech than 1900 today's to show what any global ameliorate on effort should not get in the way of.
