Rising sea levels could threaten up to 60,000 houses, 1200 commercial buildings and 250 kilometres of highway in NSW by the end of the century, a report by the federal government’s Climate Commission says.
The report, The Critical Decade, NSW Climate Impacts and Opportunities, says extreme weather events of recent years – including heatwaves that swept NSW in 2009 and flash flooding in Sydney in March – will become more common as the average temperature across the state rises by 1 to 5 degrees by 2030 compared to 1990.
By 2070, the number of days above 35 degrees each year in the east of Sydney will triple from three to nine. While heatwaves, droughts and bushfires will increase in frequency across the state, sporadic and torrential downpours could also become more common as the warmer climate raises ocean temperatures.
The report warns of the health risk the hotter, drier climate will pose to children and the elderly, as well as people who work in heat-exposed jobs or have low incomes, and says that western Sydney in particular will suffer, due to an urban heat island effect.
Dominique Hes, a Senior Lecturer in Sustainable Architecture at University of Melbourne, said the western suburbs of Sydney were particularly susceptible because they were home to vast tracts of new, low-rise developments with few fully-grown trees and parks. “They’ve also got large areas of bitumen and new houses with dark coloured roofs – both of those absorb the sun’s energy.”

In warm weather charcoal tiles could get as hot as 80 degrees, while white tiles only got to about 35 degrees, Dr Hes said. “That’s almost 50 degrees of temperature you’re not capturing per roof – a huge difference.
“The best option is to have white roofs and also to improve shading. If you have more trees and plants, they create a micro-climate. That helps with the heat island effect, which can heighten temperatures by as much as 6 degrees. That’s very dangerous for vulnerable people.”
The report for NSW also warns that a forecast 1.1-metre rise in the sea level could threaten between 40,000 and 60,000 houses – at a value of up to $18.7 billion – and flood parts of Sydney airport, the busiest in Australia. The predicted rise was “modelled by the Australian Government to assess the highest likely risk”, and could wipe out more than 170 kilometres of railway, with a replacement value of up to $1.3 billion. Wollongong would lose up to 51 kilometres of track, and Newcastle as much as 56 kilometres.
The chief commissioner, Tim Flannery, said that “changes in Sydney’s climate will have far reaching implications for health, agriculture, tourism, water security and biodiversity.
“The silver lining is that in addressing climate change we can also benefit from the global clean energy boom. NSW has a legacy of producing the best minds in the world when it comes to solar technology. Four out of the big six solar manufacturers in the world are led by University of New South Wales graduates,” Professor Flannery said.
By 2020, it has been estimated that $43 billion will be invested in clean energy in Australia, including $20 billion in solar.
The authors of the report, climate commissioners Will Steffen and Lesley Hughes, said the decade ahead would be a critical time for action. “NSW is home to over a third of Australians, 31% of the national economy and is highly vulnerable to climate change,” they write in the report, which will be discussed at a public forum at Parramatta Town Hall tomorrow night.

Alas, the damage to Old Sydney Town, is merely the tip of the iceberg,
It is also a given, the error bars shown on the current IPCC AR4 report are quite conservative, and the new upcoming AR5 report will be far more refined to include the peer reviewed science data, from a satellite called G.R.A.C.E. .
We are looking at extensive damage along the entire coast line of Australia, and the numerous islands in our Pacific sphere of influence, as was claimed by the former self proclaimed "Marshall of the Pacific". Thus creating a possible future conundrum, given the current anti-refugee immigration mess, caused by the out of control Murdoch Media Megaphone propaganda FUD machine.
Extract from Chief Seattle's speech given in 1854 :-
"Whatever befalls the Earth - befalls the sons of the Earth. Man did not weave the web of life - he is merely a strand in it. Whatever he does to the web, he does to himself."

I found the comments in a rival tabloid's (The Daily Telegraph's) article today "Climate commissioner Professor Tim Flannery said temperatures on rise in Sydney's west" at the moment, 172 comments, really disheartening for the Cause. Out of the 172 views expressed, there was not a single comment supporting Prof Flannery, with most poking fun of him and his previous gallant but failed predictions on the dams drying up, and several dozen lamenting a perceived waste of public money in the form of his salary. Thank Marx we have The Conversation for a more balanced viewpoint in the comments section - at this moment, both (all two) of them.

If there is 1.1 m sea-level rise, this will mean that the length of Sydney Harbour waterfront real estate will increase.

Justin, you can thank the authors of the climate commission's highly alarmist political report for the error in your second paragraph. In regard to projected increases in average temperature across NSW the report states: Page 3..."Average temperature across NSW is expected to increase by 0.3–1.5°C by 2030 and by 1.0–5.0°C compared to 1990."
It is clear from the rest of the paragraph that the 1-5 degree rise is projected for 2070.
Perhaps you can report this error to the climate Kommisars, as they no longer return my emails and have thus far refused to answer any of my questions.
Marc Hendrickx

Note also Justin that the report is alarmist, heavily biased, contains distortions and misrepresentations, fails to take historical extremes into account and relies significantly on the grey literature. Everything you would expect from a political document?
On the plus side the recycled paper I have printed it out on burns really well in our wood fire. Now where are those marshmallows?

You have nothing constructive to add to the debate Marc and you seem to be keen to try to derail every article about climate change.

I am afraid I missed your point. Perhaps you inadvertantly deleted it before posting. Since I am interested in what you might have said, I am wondering if you would mind re-entering it for us.

This has no longer become a debate. It is an entrenched spin exercise from both sides.

My earlier post about Steffen's apparent contradiction about extreme weather events, implying they are caused by man made CO2 is also confusing.

Ian, indeed John Nicol has been the most gentlemanly of those charged with stirring the FUD pot on global warming, sea rise and ocean acidification -- though those latter two they try to hide from discussing, since almost anyone can measure them.
The Heartland boys up here, sponsored by the American Petroleum Institute, etc., have been busy funding other fake 'institutes', even Down Under, for which I'm apologetic to all Aussies for us not being able to keep our criminal element within our borders.
The fellow who exposed the secrets of Heartland's meddling "hands across the seas" trickery is Peter Glieck...

Oops, it's just so easy to guess which articles will have Marc (with a "c"), Philip and maybe the few others serving the combustion industry! I mean even a Yank can guess the articles that our Heartland handlers will turn over rocks to get lockstep, if laughably manipulative, anti-facks put up against the tide.
Still waiting for you to take the bet Monckton wouldn't, Marc. Or maybe you & Philip can alternatively start a trust for your offspring to fall back on if, just perchance, your unreal view of reality are wrong. If you did that, maybe your robotic comments against sea rise, global warming and ocean acidification could carry a little weight?
Ahhh, silly me, you don't care. You'll be up in the front of the line when any compensations are collected, won't you?

For me to pretend that I'm qualified to judge the science would be dishonest. To believe that I am would be poor mental hygiene. I'm therefore limited to judging the scientists.
Delusions of grand conspiracy notwithstanding, the vast majority of the best qualified warn of substantial risks, for which humanity is probably responsible. Two independent studies, employing different methodologies, produced similar conclusions: 97% agree, 2% not sure, 1% disagree.
Against such a majority, would a sane and decent person refuse to take prudent precautions?

Well said David. Like you I am not a scientist, but I read a lot of science journals and your conclusions tend to support what I am consistently reading. Only politicians and their believers with their 'bent' perspective, seem to protest.
Regretably Professor Flannery's comments a few years back that Eastern Australian dams would run out of water later this decade came at a time when we experienced a double La Nina event, which subsequently flooded the country and filled the dams. Easy to grab…

I couldn't agree more. People should be able to express an opinion on the science or public reactions to it in a civilised way and expect that others who respond to them will also be polite and discuss the details of each comment, not the background of the person who made the comments, or make use of ANY abusive or unkind words. Unless that policy is strictly adherred to, the debate degenerates into a slanging match.

Nicol is back! Indeed Heartland funding is still in force Down Under. But John, where was that bond or trust you were going to put some $ in for your descendents, just in the off case you turn out wrong to shill for our combustion boys up here?
And where was that bet -- you know, the one Monckton refused because he knew better that to bet against emissions problems. Are you of the same mind now too?
To bad Glieck exposed all the slush funding we've been spilling onto phony "institutes" down there, eh?

"People should be able to express an opinion on the science or public reactions to it in a civilised way and expect that others who respond to them will also be polite"
This is a strawman, of course. The issue is people who insult scientists by actually or effectively accusing them of fraud, criminal or otherwise, and then turn into crybabies when they're told they're not telling the truth.

I am most curious that the headline reads NSW but the article discusses Sydney.
Um, yes, I know from growing up in the southwest of NSW, Riverina more precisely, that the Sydney-siders really do think NSW means Newcastle-Sydney-Wollongong, that to them Bathurst is the far west while the rest of us are simply 'from the country'.
Which indicates a lot that's wrong with the debate, beyond the admonitions above to keep things civil, partly due to the way media works in taking its generalised snapshorts…

OMG, Watch out the sky is falling. WOW. Amazing, that people who claim to be intelligent, can be so dumb.
I really need someone to explain to me in very simple terms,(am simple person)why, with all the alleged hysteria regarding Global warming and sea levels rising, why authorities all around Australia are still allowing and supporting building of infrastructure and homes in areas that are low lying and subject to inundation ?
I have not witnessed any evidance of said authorities adopting policies to sustain the alleged claims being made by global warmer supporters, either by the Federal Govt or state authorities. Something which I find rather contradictory.
I also know for a FACT, the Indian ocean has not risen one centimeter during my lifetime. So come on folks, give us some REAL FACTUAL information, something that CAN be supported and substantiated to hold up all these airy fairy claims being made.

This is my favourite comment so far. (It's not a competition.) "Alleged hysteria"... Global warming is so dubious that even the view that it's pure hysteria is merely "alleged"? What can that even mean? Oh, I see, you are "simple person".
