MEDIA RELEASE Penrith by-election: Greens vote surge, bad news for Labor in Balmain The doubling of the Greens vote in the Penrith by-election underlines the level of voter anger with Labor and indicates a likely Lower House breakthrough for the party in the NSW 2011 state election. With 60 per cent of the vote counted the Greens candidate Suzie Wright has received 12.6 per cent. At the 2007 state election the Greens received 5.5 per cent of the vote in Penrith. Labor’s vote has halved to 24 per cent of the vote. The Liberals won with a primary vote of 50.9 per cent. “Labor’s failure to address the needs of Penrith and western Sydney has resulted in the crash in the government’s vote,” Ms Wright said. “Although the Liberals have received a massive swing I believe this was a vote against Labor rather than a vote for the opposition. “The swing to the Liberals is more than 20 per cent on the two party preferred vote. “The collapse of Labor’s vote puts the government and the opposition on notice. This area needs a major upgrade of public transport services. Greens MP Lee Rhiannon said that today’s results for the Greens suggests a strong result at the 2011 state election. “The Greens beat Labor in all four lower Blue Mountains polling booths. “Penrith is not normally a strong seat for the Greens so the fact that we have more than doubled our vote is very encouraging. “These results will be unsettling for Labor in state seats like Balmain and Marrickville where they are under threat from an increasing Greens demographic. “These results are in keeping with recent polls that have had the Greens between 13 and 16 per cent of the vote. “The Greens have also received a strong result in the Hawkesbury City Council by-election with our candidate Danielle Wheeler gaining 23 per cent of the vote. This is up from 10 per cent in the last local council election,” said Ms Rhiannon. For more information – 0427 861 568 — Another message from the Greens Media mailing list. Too many messages?

Cutting greenhouse gases will be no quick fix for our weather, scientists say
The research suggests that increased floods and droughts could continue long after future efforts to stabilise temperature may succeed.
Vicky Pope, head of climate change advice at the Hadley Centre, said: “We can’t say that if we manage to bring down our carbon dioxide emissions then we don’t need to worry any more. There will still be changes beyond that point.”
A team led by Peili Wu used a computer model to analyse how the Earth’s water cycle could react to changes in future amounts of carbon dioxide in the atmosphere.
It found that once carbon dioxide levels rise to a high level, even sharp reductions fail to prevent longlasting impacts on snow and rainfall.
This is down to accumulated heat in the oceans, which dissipates slowly and drives changes in the water cycle as it does so.
Writing in a paper to be published in the journal Geophysical Research Letters, the scientists say: “Our results suggest that relationships between precipitation and warming may significantly underestimate precipitation changes during periods of [greenhouse gas] stabilisation or reduction.
“The inertia due to the accumulated heat in the ocean implies a commitment to changes long after stabilisation.”
They add: “This effect must be taken into account when assessing the implications of various mitigation options for flooding, water supply, food production and human health.”
The study simulated the effects of a steady rise in carbon dioxide levels until the equivalent atmospheric concentration topped 1,000ppm (parts per million).
The current CO2 level is just over 390ppm, and most policies aimed at tackling climate change suggest the world should not exceed 450ppm-550ppm, though this would require significant curbs on carbon pollution.
In the study, the scientists then rapidly brought the CO2 level back down to pre-industrial levels of around 280ppm.
In practice, this would be impossible – without geo-engineering techniques that could actively remove it from the atmosphere – but the scientists wanted to see what would theoretically happen.
The model showed that, while temperatures dropped sharply as CO2 was reduced, the disruption to precipitation continued for several decades.
How the rainfall may change for a particular region is a more complicated question, though the scientists said their model suggested significant drying in South America, Southern Africa and Australia.
