Sea level rise is expected to continue for centuries. In 2007, the Intergovernmental Panel on Climate Change (IPCC) projected that during the 21st century, sea level will rise another 18 to 59 cm (7.1 to 23 in), but these numbers do not include "uncertainties in climate-carbon cycle feedbacks nor do they include the full effects of changes in ice sheet flow". More recent projections assessed by the US National Research Council (2010) suggest possible sea level rise over the 21st century of between 56 and 200 cm (22 and 79 in).

So move anything important to more than 7 feet above sea level, or start building a wall.
There, sorted it.

Sea rise map

Not to knock this study, But where I live in Ny and the surrounding counties we are any where from 315 to 450 feet above sea level. So that map showing New York state as under water is bogus. New York city is another matter. Along with coastal areas of NY.

edit- I should have clicked on the state. It shows the major metro areas that would be under water. 9 million poeple would be displaced.

What is interesting is to compare that map that shows the western and eastern seaboards under water, with the population dispersal map during the last USA elections. Very similar. Looks like the majority of Americans live in flood risk areas!

I think I am right in saying that 98% of all major cities are either on the coast or major waterways. And that is because until 1830 the major transport systems were by boat.

We continue to pollute The World.

Meanwhile, small positive progress is made:


Global warming, ethanol, and will-o-wisp solutions

Contrary to common perceptions, corn-based ethanol is a useful technology on the road to reducing carbon emissions...

... So, should we discard corn-ethanol outright? No. But we should view it as a testing ground for the real solution of cellulosic ethanol. It is a solution that creates winners everywhere.



The world does need a red line – on climate change

Activists agree we must fight the Keystone XL pipeline in the US, but also chip away at the political power of the fossil fuel industry...


China vows to tackle air pollution

Beijing unveils measures to close old polluting mills and smelters and cut coal use to halt worsening air pollution...


All too feeble or small parts of the beginnings of a world-wide solution?

Another small step for the fossils to go clean?


Carbon capture and storage to be monitored by cosmic rays

Carbon capture and storage (CCS) is a proposed route to mitigate fossil-fuel greenhouse gases' impact on Earth's atmosphere, oceans and climate.

In CCS, CO2 is captured from fuel burning at the power station, and pumped back down into the very rocks that maybe once yielded that fuel. Likely storage sites for CO2 will be depleted gas and oil fields one to two km down, with many candidates in the old oil and gas fields of the North Sea.

A few test sites around the world suggest that CO2 can indeed be returned to the deep Earth successfully, but attention has now turned to monitoring its behaviour at depth...

And another not-so-small step for cleaner energy:


Pentland Firth tidal turbine project given consent

Work is to begin on the largest tidal turbine energy project in Europe after the Scottish government approved it. MeyGen is to install the tidal array in stages in the Pentland Firth, between Orkney and the Scottish mainland...

... When fully operational, the 86MW array could generate enough electricity to power the equivalent of 42,000 homes...

... a second phase would eventually see up to 400 submerged turbines at the site, generating some 398MW.

It will be the first commercial deployment of tidal turbines in Scottish waters...



Shame there's not more detailed information, especially as the power utilization for tidal stream is very different to that listed for such as wind power...

Still, some pretty big numbers and a good start. Shame the ignorant press also list the ballast for the turbines just for the sake of 'big numbers'. Very dumb.

The turbines and operation should turn out to be something far far from dumb. We may even get a good side benefit of them in effect enforcing environmental sanctuaries where sealife can thrive safely free from the apocalypse of our fishing fleets...


All on our only one planet,
Martin

"Make is so" engineering on display ...

http://www.foxnews.com/us/2013/10/02/firefighters-alarmed-by-dangers-posed-by-rooftop-solar-panels/

Firefighters alarmed by latest rescue risk: solar panels

Firefighters across the nation are alarmed at the prospect of battling blazes in buildings topped with solar panels, which can create new risks of roofs collapsing, an inability to gain footing and even potential electric shock.

...

“We may very well not be able to save buildings that have alternative energy,” New Jersey’s Acting Fire Marshall William Kramer told The Star-Ledger.

Experts told FoxNews.com that the biggest danger posed by the panels is that they continue to send voltage down from the roof throughout the building even after power is shut down. In a conventional building, firefighters typically cut off the electricity leading into the house before entering.

“First of all, solar panels are designed to generate electricity any time there’s light received by the panels, and that happens in low-light settings as well,” said Ken Willette, a spokesman for the National Fire Protection Association. “So inherently, those are charged electrical appliances … there’s a shock hazard.”

Solar panels also frequently utilize the very space firefighters use for rooftop ventilation during structure fires and create potentially dangerous conditions for slips and falls.

“In some applications, the solar panels have covered 100 percent of the roof, which allows the firefighter no room to operate,” Willette continued. “That’s not what you want to have happen when you’re operating on a pitched roof.”

Note the jaundiced and highly ironic spin/angle put on a perfectly good story...


Interesting to see that so much is being done in spite of the sponsored denialist FUD. Also interesting is seeing who it is that is having to pay whilst the polluters continue to FUD and pollute and profit.

From an article elsewhere, the present cost of cleaning up 1 ton of CO2 from the atmosphere has been costed to be about £600 per ton...


Such is the game of news...

For a rather unusual angle:


Giant solar mirrors bring light to shady Norwegian town

A town in Norway has installed giant solar mirrors to bring some sunlight into the town in winter.

The mountains surrounding Rjukan put the town in the shade throughout the long Norwegian winter...



I'm sure some Scottish villages/towns hidden down deep valleys could benefit from that also...


A ray of hope?

Martin, what methods do they apply to take this CO2 out from the atmosphere?

Thanks for that.


From that article:

... Carbon dioxide is the most important of the gases that they track, but only about half of the CO2 that's emitted by human activities remains in the atmosphere, with the rest being absorbed by the plants, trees, the land and the oceans.

Upsetting the balance

Since 1750, global average levels of CO2 in the atmosphere have increased to 141% of the pre-industrial concentration...

... "The laws of physics and chemistry are not negotiable," said Michel Jarraud.

"Greenhouse gases are what they are, the laws of physics show they can only contribute to warming the system, but parts of this heat may go in different places like the oceans for some periods of time," he said.

This view was echoed by Prof Piers Forster from the University of Leeds: "For the past decade or so the oceans have been sucking up this extra heat, meaning that surface temperatures have only increased slowly.

"Don't expect this state of affairs to continue though, the extra heat will eventually come out and bite us, so expect strong warming over the coming decades."




There lots that goes into the mix but however you might wish to stir the story, the question is only of how soon our industrial-scale CO2 pollution folly can continue.

The questions are only of how soon we get bitten and how hard.

An important part of any system is that of what feedback you get. Here is hope of one feedback mechanism that is just a click away that might give some positive help:


Avaaz: Stand with the Philippines

Why this is important

Last weekend’s Super Typhoon Haiyan made landfall in my family’s hometown. The devastation is so staggering, that I’m struggling to find words to describe how I feel about the losses and damages we have suffered from this.

... the superstorm was not just another natural disaster -- it was made stronger and more deadly by human-caused climate change. For too long, those countries with the greatest capacity to act and greatest responsibility for the problem have shirked their obligations to cut pollution as the science demands...

So I’ve taken a rare step as a public servant -- I’ve gone beyond the usual conventions... Together our voices can push the governments meeting at the UN climate summit happening now to ratchet up pollution controls...



Feedback such as this is just one small but important step to highlight the folly to our world of a few fossil fuels industrialists profiteering at the far greater expense of polluting the ENTIRE rest of the world.

Clearly this disaster has affected him personally and very strongly, and of course he has all our sympathy and empathy.

... the superstorm was not just another natural disaster -- it was made stronger and more deadly by human-caused climate change.

There is no proof of that, and I would suggest a remark fuelled from emotion, but quite understandable in the circumstances.

Absolutely correct.

Global climate change swings like a pendulum do, but this pendulum also follows
a circle too during it's swing cycle. Actually what it's doing is responding to
the changes in axis of the Earth around it's poles plus the changes in tilt too.
Also, researchers have detected an other anomaly regarding planet Earth and not
just that of Global warming. The Earth's magnetic fields strength is weakening
and those odd areas on the planet where one can detect zero magnetic field
strengths are expanding. This results in less protection against the solar winds
and the result being that the polar regions will see a thinning of their ozone
layers. Nothing much to worry about as this occurs on a regular basis every
100 thousand years...if my memory serves me well. What is actually happening
here? is the Earth loosing it's magnetic field with a holocaust to follow?...
...No, looks like we're going through the natural motions of a polarity change
and one day magnetic North will be the old South and vice-versa.
