This is very insightful information. Thank you for posting it.

The flip side of this is at http://www.global-warming-forecasts.com/water-supply-shortage-water-scarcity-climate.php

The flop side of this is ocean acidification. More water but oh, how acidic http://www.order-salmon.com/salmon-global-warming-salmon-climate-change.php

Hi Anon!
Not so much time, really. All it will take is one to two metres to close every port in the world, and disrupt many coastal highways. It will also displace millions of people, who will want to live at your place.

To get 80 metres requires the melt of most of the ice sheets and glaciers which - even with say +10 degrees above present day temperatures - would take several hundred years.

But between one and five metres by 2100 is much more likely. The melt is occurring slowly at first - we've seen about 180 mm so far over the last 100 years. By 2040 if we see even another 100 mm we will be in for 2 to 5 metres by the time your grand children are old folks.

So best to make arrangements and live like its going to happen to set those grandchildren a sensible example. Take care!

According to the "Year vs Sea Level Chart", we have plenty of time to get our affairs in order. What conditions could accelerate the 80 meter mark to say 2040?

Hi Jason!

Good to see you visiting sites like these so you can find your own 'truth' in these interesting times.

Please keep an open mind and keep on studying so you can find the information that resonates best with you and thus prepare yourself and your family for the 'interesting' times ahead.

2011-06-29T11:10:33.223-07:00

Why do people think that "Global Warming" is man-made? Are those people not aware that the Earth has had several climate changes in its lifetime? There is an Ice Age, then Global Warming occurs. Then, Global cooling occurs until you have another Ice Age, and the process starts over.

Some people are just too gullible!

Just discovered your blog Nigel - excellent work. Led to you by David Williams excellent story in The Press (http://www.stuff.co.nz/the-press/news/christchurch-earthquake-2011/5130776/Flood-risk-grows-as-ground-slumps)

Writing to influencers like newspapers, MP's council is EXACTLY what we need to do. In the recent Auckland spatial plan discussion, sea level rise got a paragraph out of 220-odd pages. They seriously have their heads in the sand going by your 2100 Auckland map!

Hi!
Thanks for the ref to Mahurangi Mag.

I used Google Maps sea level rise applet. Unfortunately Google has dropped the ability to use such applets, so we cant use that process any more.

I;m looking for an alternative, and will let you know if ever i find one.

Thanks for your interest.

Yes, very informative, and interesting, nice maps thanks, if only people cared about the world they are going to leave one day, people dont want to sacrifice for tomorrow generation. Its always a good thing to plan, like on vacation, try doing things that are a little more eco friendly, like here, http://caribbean-guide.info/activities/diving.and.snorkeling/
I love diving, its a great way to see new things, and if the shore lines continue to rise, it may be an everyday occurrence for the majority of people! haha!

2010-06-20T20:23:49.890-07:00

This is such an important project! Home owners currently are extremely ill informed as to the impacts of sea level rise on their property. Long before water levels even really being to impact property, coastal home owners will be counting the cost of the THREAT from rises in insurance, rates and possible market value drop.

Not all properties are affected the same way - it is a complex mix of soil type, topography and water movement. All coastal property owners should get a Climate Change Impact Assessment done on their block to find out the risk.

Don't be a coastal home owner who is eventually left with a property you can't develop, occupy or resell.

2009-12-25T21:36:12.722-08:00

Thanks for your interest, you raise some good points.

The melting of the ice sheets is underway and it will only stop when the CO2 levels return to pre-industrial levels.

I postulate a 1000 to 2000 year melt out, but it could be slower, or faster, depending on whether we continue to take carbon out of the ground and put it into the air. Its our choice.

I started by looking at the effect of sea level rises of a metre or so, and what we should do about that. But when that view is blended with peak oil we find that we only have another 5 to 10 years from today to use oil to rebuild our global coastal infrastructure.

So we can only do that once, before our primary energy source is effectively gone. If we must do it once, then we have to build for the probably longer term future. That is why I recognise total melt of 80 metres sea level rise, and a prudent step above that for key infrastructure.

Hence - The 100 metre line.

2009-12-17T19:15:15.827-08:00

ROFLMAO! I was looking up what sea level rise could be expected from a 2C or 3C temperature increase over 100 years, and I came across your absurd maps. Do you SERIOUSLY think that sea levels are going to rise by 100 meters within a time frame of interest of, say, 100 years? That entails the melting of the entire Antarctic and Greenland ice caps - a process which will take THOUSANDS to MILLIONS of years at bare minimum (assuming absurd levels of temperature change). Even your sidebar testifies to this absurdity when you project sea levels out to 2500 AD to 2700 AD. Seriously, we can predict the future 500 years from now, the level of technology humans will have achieved, and we have complete knowledge of all the processes that affect climate?

If this site wasn't a complete joke, you could perhaps do maps of, say, what the shoreline might look like with a 2 meter rise in sea level (projections indicate around 80cm rise by 2100). Even that map will completely miss the point that people aren't going to be displaced by sea level rise associated with global warming: Hundreds of Millions in China have already been "displaced" from the countryside into cities; Tens of Millions in Europe and America are "displaced" annually because almost nobody will live at the same location they were born by the time they are at university or working. Mass displacement assumes people are static over decades - a complete mis-assessment of reality.

You're better off quantifying other potential effects of global warming. The sea level stuff is academically "interesting", but quite a waste of time practically speaking.
