Free public transport
Free Public transport campaign from the Scottish Socialist Party
- Its time has come. I will dig around one day for figures to support that it will be cheaper for the community to have free public transport than not to due to the expense of congestion, pollution, road deaths, road works, property buy-outs for new roads etc..

Environment is secondary to private profits
May 22, 2008
From The AGE
Investing in renewable energy is being ignored to keep fossil fuels burning.
THE idea that coal-fired electricity generation can continue to be the major contributor to global electricity generation and the world can still restrict carbon dioxide emissions to a level constant with holding climate warming below 2 degrees is a fairytale, according to letter in the premier science journal Nature (published online, May 7, 2008).
Vaclav Smil, of the University of Manitoba, in Canada, makes a new point that is critical to the debate as it is being run by state and federal governments in Australia: "Carbon geosequestration is irresponsibly portrayed as an imminently useful large-scale option for solving the challenge. But to sequester just 25% of carbon dioxide emitted in 2005 by large stationary sources of the gas we would have to create a system whose annual throughput by volume would be slightly more than twice that of the world's crude-oil industry, an undertaking that would take many decades to accomplish."
And yet the Brumby and Rudd Governments persist in pouring money into geosequestration research at the expense of developing solar energy, among other renewable alternatives. Last month Premier John Brumby announced a $127 million package to develop "clean coal" including a $110 million fund to establish new large scale, pre-commercial carbon capture storage demonstration projects. These latest commitments will take Victoria's total clean coal investment to more than $244 million since 2002.

Australia Stuck in the coal age, when the solar century has already begun
Martin Ferguson let the cat out of the bag shortly after the Budget, when he said that carbon capture and storage would be "essential for the long-term sustainability of coal-fired power generation." With those words, he betrayed the fact that his Government prioritises the coal sector's profits over climate protection.
If that seems like a long bow to draw, look at the evidence that the Budget presents.
In the vital area of commercialisation of technologies, the myriad of renewable energy options that are ready to roll out now were allocated precisely zero for the coming year, with only $125 million in this term of Government. Next to that, the pipedream that is 'clean coal' received $35 million this year and $250 million this term.
When immediately called to task by the geothermal industry, which was, like many other renewable technology developers, calling for urgent commercialisation funding, the Government chose to make that sector an ad hoc $40 million grant, instead of shifting funding priorities. What's worse, instead of taking the $40 million from the coal sector's windfall, the Government took it out of the Energy Innovation Fund, money that had been earmarked for research into storage of solar energy.

Renewable energy has the potential to power our whole country with zero emissions within the near future, something coal cannot dream of. However, in terms of fast, cheap emissions reductions, nothing can beat energy efficiency. The Greens' proposal for a systemic infrastructure upgrade across Australia, to increase efficiency by 30 per cent or more across the economy, stands in stark contrast to the Government's piecemeal, tokenistic approach. A few tens of millions in rebates, grants and loans will cover a tiny percentage of homes, businesses and industry, while the cash-only offer fails to address the other well-known barriers to energy efficiency, such as lack of information and priority. Tackling energy efficiency provides a tremendous economic and social opportunity, let alone the climate benefits. Yet it was largely ignored by the Rudd Government.

Civilization's last chance
From LA Times
A few weeks ago, NASA's chief climatologist, James Hansen, submitted a paper to Science magazine with several coauthors. The abstract attached to it argued -- and I have never read stronger language in a scientific paper -- that "if humanity wishes to preserve a planet similar to that on which civilization developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO2 will need to be reduced from its current 385 ppm to at most 350 ppm."
Hansen cites six irreversible tipping points -- massive sea level rise and huge changes in rainfall patterns, among them -- that we'll pass if we don't get back down to 350 soon; and the first of them, judging by last summer's insane melt of Arctic ice, may already be behind us.
So it's a tough diagnosis. It's like the doctor telling you that your cholesterol is way too high and, if you don't bring it down right away, you're going to have a stroke. So you take the pill, you swear off the cheese, and, if you're lucky, you get back into the safety zone before the coronary. It's like watching the tachometer edge into the red zone and knowing that you need to take your foot off the gas before you hear that clunk up front.
...
Hansen's words were well-chosen: "a planet similar to that on which civilization developed." People will doubtless survive on a non-350 planet, but those who do will be so preoccupied, coping with the endless unintended consequences of an overheated planet, that civilization may not.
Civilization is what grows up in the margins of leisure and security provided by a workable relationship with the natural world. That margin won't exist, at least not for long, as long as we remain on the wrong side of 350. That's the limit we face.

World carbon dioxide levels highest for 650,000 years
From The Guardian (UK)
The figures, published by the US National Oceanic and Atmospheric Administration on its website, also confirm that carbon dioxide, the chief greenhouse gas, is accumulating in the atmosphere faster than expected. The annual mean growth rate for 2007 was 2.14ppm - the fourth year in the last six to see an annual rise greater than 2ppm. From 1970 to 2000, the concentration rose by about 1.5ppm each year, but since 2000 the annual rise has leapt to an average 2.1ppm.
Scientists say the shift could indicate that the Earth is losing its natural ability to soak up billions of tonnes of CO2 each year. Climate models assume that about half our future emissions will be reabsorbed by forests and oceans, but the new figures confirm this may be too optimistic. If more of our carbon pollution stays in the atmosphere, it means emissions will have to be cut by more than is currently projected to prevent dangerous levels of global warming.
