Herald Sun - Oil's more distant future

THE credible forecast of $US200 oil and the latest trade figures provided an important and instructive footnote to the Reserve Bank's formal abandonment of the 'Rory clause'.

Apart from, that's the oil price forecast, carrying an ominous but confusingly complicated message on petrol prices - fortunately, five years or more into the future.

Radio NZ - NGO says Pacific Forum fails on climate change and trade

Oxfam New Zealand says the concerns of Pacific Island countries are not reflected in the outcomes of the leaders’ summit in Cairns.

Over the two key issues before the summit, the leaders agreed to immediately begin negotiations on a trade deal in goods and services, PACER - PLUS, and want developed countries to cut greenhouse gases by 50 percent by 2050.

But this comes against calls for a delay in the trade negotiations to allow the island countries to consult internally, while the small countries had called for far more substantial emission cuts.

The Australian - BHP to resume operations at Hay Point Coal terminal

BHP Billiton Mitsubishi Alliance will resume normal operations at Hay Point coal export terminal in northeast Queensland after they were disrupted by Greenpeace protesters.

The Australian - $50m for Pacific climate

AUSTRALIA is to spend $4.3 million upgrading stations which monitor sea levels across the Pacific.

Climate change has been the hot topic at the annual Pacific Islands Forum, held this week in Cairns.

Climate Change Minister Penny Wong has released more details of how $50 million in previously-announced climate funding for Pacific nations is to be spent.

As well as money for the sea level stations, $6 million will go towards adapting fisheries and crops to climate change.

TV NZ - Auckland public transport use hits a high

The figures come shortly after the planned regional fuel tax to fund further public transport development was canned by the government.

It has also prioritised new road projects such as the Newmarket Viaduct upgrade and Victoria Park Tunnel and the Western Ring Route.

NZ Herald - Kiwi takes climate hotseat for Deloitte

The irony of criss-crossing the world in carbon-emitting aircraft as he advises clients on how to move to a low-carbon economy is not lost on Nick Main.

NZ Herald - Editorial: Seize chance to lead way on climate change

Over the years, there has been much debate over where this country should position itself in its response to climate change. Should it place itself in the vanguard of countries by setting ambitious greenhouse gas emissions targets? Should it play it safe and become what the New Zealand Institute once described as a fast follower? Or should we be timid in the belief that self-sacrifice would be futile, especially when our economic base provides grounds for special pleading? The question is again relevant as the Government prepares to name the emissions target for 2020 that it will take later this year to Copenhagen, where a climate treaty to succeed the 1997 Kyoto Protocol is set to be negotiated.

ABC - Govt 'playing politics' with climate bill

Federal Climate Change Minister Penny Wong is resisting pressure to separate the renewable energy target from the Government's emissions trading scheme legislation.

Ourier Mail - Transport use booms but reliability of buses queried

PUBLIC satisfaction with buses has fallen, with reliability and efficiency dropping to their lowest level in a year, says a new survey.

The latest customer satisfaction survey released publicly today, the TransLink Tracker, shows buses are considered the southeast's most unreliable and inefficient form of public transport

ABC - Cougar seeks coal seam gasification nod

Cougar Energy says it will ask for Queensland Government approval to go ahead with full-scale underground coal seam gasification in the South Burnett, in the state's south-east.

WA Today - Rural people need climate help: alliance

Rural communities need more help to cope with climate change, the federal government has been told.

The Australian - Why not trade our way out of the climate crisis?

It has been conventional wisdom among experienced trade negotiators not to link concessions on trade policy to changes in other policy areas, such as national security. But we are talking here about issues that are economic in nature. The linkage is heightened by attempts to use environmental issues to justify the erection of green barriers to trade with environmentally recalcitrant nations or industry sectors. We need to head off firmly once and for all such growth-reducing practices.

Mackay Daily Mercury - Talbot predicts strong coal future

The economic downturn that has been on the quills of every pen for the past six months is showing signs of abating and even while experts are still unsure about what the future holds, all signs point to good news.

Former head of Macarthur Coal and mining magnate Ken Talbot is reported as telling a mining conference this week that the global economy would almost certainly exceed “pre-crash levels”, adding that “the next boom would be even stronger than the last one”.

Radio NZ - Climate change may trigger conflict, says UN diplomat

Ajay Chhibber, the head of the United Nations Development Programme for Asia and the Pacific, says climate change represents a significant threat to human security.

Electric cars will be exempt from road user charges for four years under legislation passed by Parliament last night.

Gizmag - World’s first commercial fuel cell Unmanned Aerial System

Hydrogen-electric powered UAS will bring important new capabilities - reduced acoustic signature, smaller size, as well as increased effectiveness in increasingly important persistent intelligence, surveillance and reconnaissance (ISR) missions. Where battery performance limits the effective use of these promising systems, Horizon’s next-generation fuel cell power systems will improve versatility and open new mission possibilities for small aircraft such as BlueBird’s Boomerang UAS. In addition to increasing flight endurance, Horizon’s new fuel cell system also makes it possible to increase the capability of smaller and lower cost aircraft by integrating more power draining electronic devices, such as electro-optical sensors, infrared cameras and laser designators.

I've been thinking about the threat to Pacific nations from rising sea levels. The main threat is to people living on coral atolls, which by definition are just above sea level because they have been built by undersea life plus wave action.

The funny thing about coral atolls though is that they already have an automatic sea-level adjusting mechanism built in. The coral is alive and when sea levels rise the coral can theoretically rise with it.

Many atolls have a "hollow" shape when viewed from the air, because the original volcano (seamount) that the coral grew around has sunk back into the sea-floor (following a principle called isostasy)

This mechanism was first discerned by Charles Darwin. - As the volcano sinks, the coral reef rises. This natural mechanism has also worked successfully in past millenia despite sudden large rises in sea level such as the one that occurred at the end of the last ice-age, 15,000 years ago.

So what's the problem now?
My view, in one phrase, is: "reef health".
Anyone who's travelled in the Pacific will have seen that modern pollution and over-fishing have killed many of the coral reefs and stopped them growing.

I wonder whether instead of planning for a massive influx of climate refugees from Pacific nations, Australia should be investing in "reef health" so that these atolls can continue their levitation trick?

Good comment,Cretaceous.With reef health I think increasing ocean acidity is going to be a major factor as well.Also,the rate of sea level rise could outstrip the coral's capacity to keep pace,even if it were healthy.

Australia certainly should be investing in reef health for any number of reasons,apart from atolls.
However,there is so much damage now inherant in the overall system that I think that the atolls will no longer be inhabitable.This is where adaptation comes in and Australia should be facilitating and supporting this.There are numerous high islands in the South Pacific which have populations culturally similar to the atoll populations.These are the obvious first choice for resettlement.Australia should be facilitating this with a mind to the wishes of the islanders.

This process is hardly helped by PM Rudd telling the Fijians to rise up against their government.

You're right Thirra. There have been some very depressing articles about Acidification in the news recently.

Like Madge used to say in those old Palmolive ads, "You're Soaking in It"!

I have sailed through the Pacific. Many (most?) islands aren't coral atolls eg Marquesas, Tahiti, Bora Bora, Samoa, Tonga, Fiji, New Cal etc though many have coral fringing reefs. Also sea levels are rising faster than the coral, eg the Carteret Islands. I think there will be a problem, but not nearly as big as heavily populated low lying countries like Bangladesh.

Yes Saildog, there are several groups of large high islands. The "rising sea-level" problem is only really acute on atolls - and the "immigration" problem arises because the different islands have separate national administrations (often very impoverished). - And the guys on the high islands (including the Continent of Oz) aren't inclined to help the guys on the low atolls...

I've never visited Cartaret, but just looking at the satellite photo, this is a classic example of a circular reef around a sunken ( still sinking...!)volcano.

The logic of Isostasy says that if the volcano is sinking now at a certain rate, it's probably been going down at much the same rate for thousands of years. However it's clear that the rate of growth of the coral reef has been keeping up until recent times (because the reef is still above water).

But for some reason the reef is now no longer growing like it was... hence the issue is really "Reef Health".

What are the material limits here?
How sheer can the coral walls be?
Is there a point at which, as the underlying mountain sinks the compressive strength of the coral material is exceeded and the island collapses?

PNAS has 2 open access articles on recent pH work in the Pacific
The first one is a summary.

The 20-year record in surface waters off Hawaii shows only a −0.03 pH unit change. But extrapolating backwards to the preindustrial era indicates that a modern change of −0.1 pH has already occurred. And projecting forward using well-known IPCC scenarios shows that a change of about −0.3 pH should occur by mid-century. The Dore et al. (1) data set shows that we are right on this track.

The second on is the full paper

The addition of CO2 therefore acidifies seawater and lowers its pH. Over the past 250 years, the mean pH of the surface global ocean has decreased from ≈8.2 to 8.1, which is roughly equivalent to a 30% increase in [H+] (1–3). This acidification of the sea is driven by the rapidly increasing atmospheric CO2 concentration, which results from fossil fuel combustion, deforestation, and other human activities. Models predict that surface ocean pH may decline by an additional 0.3–0.4 during the 21st century (3, 4);

Note that the atmospheric CO2 is now at 380+ ppm. That's 30 ppm above what some consider "safe".

Nothing to see here... ;-)

A few more stories (sorry I'm unable to post any full articles lately - I do hope to get back on track one day...).

guide2.co.nz - Watchdog Calls For Smarter Deployment Of Electricity Meters

Parliament's environmental watchdog, Jan Wright, today urged MPs to call in representatives of electricity retailers and lines companies and probe their plans to install "dumb" smart meters.

Dr Wright has called on the Government to be proactive with regulations and standard-setting because most of the 1.3 million new meters to be installed by 2012 will actually be "dumb" -- good for electricity company profits but little help in saving electricity or costs for householders.

The Australian - Arrow Energy gas reserves more than double

ARROW Energy's chief executive expects the company to continue to deliver reserve upgrades and said it has the capability to supply both the Fishermans Landing and Curtis Island liquefied natural gas plants in Queensland.

The Sydney-based group said it has more than doubled its proven and probable reserves, or 2P, gas reserves to 2,581 petajoules. "This is a huge reserves increase but there is much more to come - we have barely scratched the surface and we have much more to do," chief executive Nick Davies said.

Arrow's current 2P reserves are about a quarter of the size of those of Woodside Petroleum's, Mr Davies said, and these reserves have come from only one 10th of Arrow's coal seam methane land.

Adelaide Now - Rigs signal geothermal bonanza

AUSTRALIA'S largest drilling rig was officially opened in the northern Flinders Ranges yesterday, cementing South Australia's place at the forefront of geothermal energy exploration.

SA is now home to Australia's two largest onshore drilling rigs, both of which are targeting geothermal energy at depths greater than 4km.

The technology involves drilling wells 4-5km into the Earth's crust, circulating water between them through hot granite, and harvesting the heat when it returns to the surface.

Federal Resources and Energy Minister Martin Ferguson said yesterday geothermal would play a key part in the nation's ambition to generate 20 per cent of its energy from renewable sources by 2020.

One from NZ - the Timaru Herald - Local food advocates seek Aoraki links

Building a more sustainable world is the aim of a new partnership in Timaru.

A farmers' market and garden-sharing scheme are visions of Transition Timaru, which has approached Aoraki Polytechnic to provide appropriate courses.

Transition Timaru is a new society trying to build resilience to the effects of climate change and the peak oil crisis by reducing carbon emissions and creating self-sufficient communities in South Canterbury.

Peak oil is the point in time when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline.

Bob Calkin, a member of the Transition Timaru steering committee, said that in a few years, peak oil will make the global market less viable as the cost of fuel rises, and business, as usual, will not be possible. The group seeks a return to more localised food production.
