HOT TOPIC – A rising tide sinks cities

I came across this blog at which I wished to comment on in order to correct some of the assumptions, unsupported statements and mistaken beliefs.

Gareth may possibly mean well but Gareth- you simply have to be a little more logical for any intelligent person to take you seriously.

The reason why I am duplicating your blog here is because I cant seem to be able to comment on yours. Probably because you expect commenters to subscribe, which would also explain the one-sided opinions of your commenters.

I am certainly not going to subscribe to your blog or get any closer than an arms length.

Not a prob though Gareth, I’m going to comment here as much as I please and I welcome anyone else who wants to to do the same. You can too if you do desire. You see I’m not afraid to defend my views with logic and academic papers etc. I allow any comments so long as they do not contain obscenities or anythig too rude.

I must admit though that Auckland would be in trouble if the sea level rose as you describe.

Here is a question Gareth, where is all this water needed to raise the sea level going to come from and when is the rise expected?

Perhaps you or some of your followers can fill out this little table ?

I will even fill out some of the first column for you.

Water Source     Contribution to sea level rise.      Rate of  sea level rise

Arctica.                             0                                                   0.     (floating ice does not affect sea levels on melting or freezing)

Greenland Ice Cap       7 mtrs.                                         3.5mm yr max (IPCC estimates a minimum of 2000 yrs for the melt )

Himalaya Glaciers



Now after doing this research, try reviewing your article.

Good luck



A rising tide sinks cities…

by Gareth on March 6, 2013

That’s the title of my first post at New Zealand’s new The Daily Blog. It’s an attempt to underline the long term imperative provided by sea level rise, to help a general audience to appreciate that every tonne of CO2 counts. The Daily Blog launched last week. Editor Martyn “Bomber” Bradbury has pulled together over 30 of NZ’s “leading left-wing commentators and progressive opinion shapers (You mean communists dont you Gareth?) to provide the other side of the story on today’s news, media and political agendas”. I’ll be blogging there every two weeks, covering climate science and policy with an eye to the run-in to the next election in 2014. Wish me luck…

A compelling presentation Gareth.

Of course I started imagining Auckland at various points in the future. It is hard to estimate seeing that erosion will accelerate in sedimentary areas with increased exposure to wave action with sea level rise. South Auckland will become salt marsh then open water, northland becoming an island. Of the rest there will be a few volcanic cones, some basalt islands and for a time some other ridges eventually eroding to sand bars.

I shudder to even think what will happen to other cities I know plus all those low lying coastal “developments” on former saltmashes shielded at present by sand bars.

In such a future world one has to doubt the ability to build new infrastructure. I can’t see much awareness of the issues in current planning. Developers don’t pay any attention at all unless forced by regulatory bodies. Christchurch has provided an example of the folly of building houses upon sand which is to say lack of vision in planning.

It would be an interesting exercise to work out how we would actually go about building “world B” after “world A”, or significant parts of it, have been swallowed by the sea, when the use of CO2 fuels is restricted or too expensive, making of concrete likewise encumbered, steel prices exorbitant, fertilizers unavailable unless you have “eaten it first” and hungry people scrapping over food, clean water and shelter.

Exactly Thomas.

Nor did I mention the large areas of low lying or reclaimed rural lands that are so prolific in food production. South of Auckland much of the lower Waikato would become an extensive Port Waikato with the sea penetrating perhaps to Taupiri. The Hauraki plains would be inundated to a point not far short of Matamata. North, lands on the eastern shores of the Kaipara would be submerged and maybe Dargaville and surrounds. Some land east of the Kaipara is actually below sea level. I once had to instrument a pump in that area that was suspect.

Of course for New Zealand it’s drought and extreme flooding, as a consequence of global warming, that is the main concern. The current North Island drought is the worst ever experienced according to early reports, and there is the very real possibility of recurrent drought over the next half-decade if the climate switches to a El Nino-dominant mode.

Farmers by and large typically vote National, but it is National that is only making matters worse by failing to act to reduce greenhouse gas emissions. More extreme farming conditions are now a reality, with decades of warming now in the pipeline, but why continue to make matters even worse?

Well I have a few other of your posts in mind to give the same treatment as this to. But dont worry, if you come across some real facts be assured that I will absolutely agree with them.
