Green Up Moggill

light rail routes (click for bigger version)

Queensland Greens propose a city-wide light rail system to supplement the existing public transport network. Light rail has several benefits. It is quicker and cheaper to put in than heavy rail. Routes along which it runs become a focus for development, especially shops and businesses. By contrast, bus routes can easily change, reducing the certainty needed for planning for future business. Although parts of the system may run like a tram through city streets, we envisage that most of the network will be separated from roads. Some sections may run above the existing rail network in areas of high density.

In Moggill, we propose to take the light rail system through Kenmore South to Pullenvale and Moggill, with a possible extension across the river to meet the Ipswich line, depending on local consultation about a river crossing.

The alignment of the route is initially proposed to follow the Kenmore Bypass corridor, since this area was originally designated as a light rail corridor.

The actual route will be investigated taking into account environmental impacts and noise.

Before we would start drawing lines on a map, we would have an extensive community consultation to determine the ideal routing of the line, including options other than the Kenmore Bypass corridor.

This plan is part of the Greens commitment to helping you get around, without being stuck in heavy traffic. It is also part of the Greens commitment to real green jobs. It is also part of involving you in planning your own community, so let me know if you have comments or ideas of your own.

Please also remember the survey where light rail is one of the options on which to express your opinion.

The following survey arises out of many opinions I’ve heard while talking to people. There’s a limit to how many people I can talk to, so please let me know by taking the survey what you think.

You can also email me if you want to talk further.

The survey is anonymous with some checks to prevent duplicate submissions.

As always, I value community opinion.

Thanks for all the responses. Watch this space for follow-ups

Many more bicycles are sold than cars in Australia, a trend that has persisted over the last nine years. You wouldn’t think it from how little infrastructure is provided for bikes. Given the combined problems of climate change, peak oil and the obesity epidemic, getting more people out of their cars and onto bikes has to be a priority. Why it isn’t for the other parties is not for me to say; it definitely is for the Greens.

I plan on campaigning for a number of improvements in bike infrastructure, including continuing with current plans to improve the bikeway infrastructure. However, bikeways are not enough. It should be safe to ride a bike in suburban and city streets as well.

Here are some details. Watch this space as I pick up more ideas from the community.

• safe bike paths in suburban and city streets
  • bikeways are only part of the solution; local streets as well as the long-haul routes need to be safe
  • paint on a road is no protection from a vehicle weight 40 times your weight
• cycle and pedestrian awareness built into road design
  • for example if the footpath and cycle path are raised relative to the road surface, drivers crossing these paths have to be aware that they are no longer in a car-only space
• environmentally sensitive mountain biking
  • end the conflict between mountain bikers and conservationists in our green spaces
• include bikes in detour planning
  • when road construction or capital works impede traffic flow alternatives for cars are always added
  • bike paths sometimes simply disappear

If the World is Warming, How can we have very cold weather?
Global warming refers to the long-term world-wide average. Redistribution of energy from one part of the planet to another may make some areas warmer and others cooler. For example, in the northern hemisphere 2009-2010 winter, some areas experienced extreme cold. However, if you look at the distribution of northern hemisphere temperatures, what happened was that the Arctic warmed considerably. Look at the image: the Arctic region shows strong warming, with Greenland considerably warmer than usual (more accurately, less chilly), yet Northern Europe and North America are large local areas of cooling. Possibly this effect caused cold air to move south, but in any case, the cooler overall northern hemisphere in the most inhabited regions has hit the news, a slightly misleading picture when you look at the whole map.

Dead Zones
A dead zone is part of the ocean where oxygen levels are too low (less than 2 parts per million) to support life, or anoxic. Here is a site at Montana State University that provides some information. For more, see NASA’s information on dead zones. Algal blooms can make part of an ocean anoxic. In an extreme case, about 251-million years ago, the oceans became widely anoxic, as part of a mass extinction event at the boundary between the Permian and Triassic though probably that event had different causes.

How Green is the electric car?
Electric cars – in the early days of motoring, a mainstream option – are making a comeback, with variations such as hybrids and plug-in hybrids. But how green are they really? Here’s an article with more detail. Check out Tesla’s first sedan. A UK company, Riversimple, has some interesting ideas on how to build an ultra-efficient car using a hydrogen fuel cell. I remain unconvinced of the hydrogen economy because hydrogen takes a lot of energy to produce, but Riversimple has some interesting ideas, like leasing the cars rather than selling them as a way of avoiding the false economy of planned obsolescence.

Smart Grid
Something that will be talked about increasingly is managing energy use more intelligently not only to be more efficient but to fit swings in demand to swings in supply better, as a remedy for the intermittency of some modes of renewable energy. Look out for articles about the smart grid such as this one.

Electric Vehicles
Now that the Obama administration is talking up clean energy, there’s been an explosion of interest in electric vehicles, so much so that rather than summarize articles, I’ll list pointers to them here as I encounter them:

Biochar
Biochar is the idea of burning carbon-containing materials in low oxygen (pyrolysis), resulting in charcoal that can be buried in the ground, improving the soil while sequestering carbon and reducing nitrous oxide (potent greenhouse gas) emissions from the soil. Biochar can also be used to produce biofuels as a byproduct. Here’s a nice YouTube summary of Australian work on biochar:

“Clean” coal
Various projects claim to be cleaning up coal. Carbon sequestration is one of the buzz words. The theory is that you can bury the CO₂ deep underground. In practice, to do so on a significant scale would be very hard. The perceived need for carbon sequestration arises from the incorrect perception that a coal producing country like Australia cannot survive a transition away from coal, a claim that is hotly contested even by former coal supporters. Here are some contrary views:

• Quarry vision: why clean coal isn’t the answer, ABC Radio National, 25 March 2009
• Quarry vision: why coal is no longer important, ABC Radio National, 25 March 2009

• Mining stalwart sees no future in carbon plan, Sydney Morning Herald, 25 April 2009

Some obstacles: worldwide emissions would amount to around 30km³ per year even compressed down to a liquid. One power station would be a lot less but still a vast volume of toxic gas to handle. Pumping it out at high temperature through a high smoke stack dissipates it into the air, and turbulence mixes it into the atmosphere quickly. A cold leak at ground level on the other hand will not dissipate fast, and can kill people in large numbers, as occasionally happens as a result of volcanic processes. Here is a detailed critique I wrote of a “clean coal” proposal for Felton in Queensland. And here is a Coen brothers ad featuring their take on clean coal:

Forest management and climate change
The forestry lobby is big on the benefits of harvesting timber. Cutting down trees, they claim, is somehow good because new growth will sequester even more carbon. The reality is a lot more complex than that; logging old growth is almost always a net loss, and managing plantations for the best overall return on carbon emissions takes careful management. This Forest, Carbon, Climate Myths slide show covers most of the major issues.
