Climate Change activists step up opposition to coal in Hunter Valley protests from mine to port

A banner drop at a construction site for a new coal loader terminal at the Port of Newcastle in the New South Wales Hunter Valley ended when police instructed the 60 metre crane be lowered to the ground. The Protestors say they were not given warning of this action and alledged it imperiled their lives.

“We are dismayed with the actions of police here today.” said spokesperson Steve Phillips. “We conducted a peaceful protest, with trained and experience climbers, and safety as our priority. NSW Police responded with gross negligence and dereliction of duty, and placed two lives at risk. Our climbers were not even warned before the crane was lowered.”

Climate change causing increase in extreme weather in South Pacific

An international study led by CSIRO oceanographer Dr Wenju Cai has identified that global warming is causing shifts in the rain band of the South Pacific Convergence Zone causing an increase in extreme weather across the island nation states of the South Pacific. The result of the movement causes drought and higher prevalence of forest fire in some areas while other islands experience extreme floods and increased frequency of tropical cyclones.

"Due to its strong rainfall gradient, a small displacement in the [South Pacific Convergence Zone] SPCZ's position causes drastic changes to hydroclimatic conditions and the frequency of extreme weather events such as droughts, floods and tropical cyclones experienced by vulnerable island countries in the region." says the paper.

Humour: And now for the real weather report...

Sick and tired of:

• ALL those weather records being broken?
  
• Record Loss of sea ice in the Arctic?
  
• Contemptuous news readers (@kainagata) just reading the smarmy corporate news script?
  

'Weather reader' Pippa (@pippa_mackie) goes sane and tells us the straight news on our warming climate caused by greenhouse gas emissions.

Well done Strut Studios in Vancouver, and Deep Rogue Ram, and @heatherlibby for writing the piece: Weathergirl Goes Rogue.

Not enough water: food production, carbon sequestration and climate change

A new study has found that there is not enough freshwater to meet the anticipated competing demands of water for food production for the global population of about 9 billion by 2050 and water for optimal growth of biomass for carbon sequestration for climate mitigation. As food production is essential, the authors of the study conclude that large scale carbon sequestration may not be realistic as a major method of climate mitigation, and we may need to rely more on direct reduction of emissions.

We rely on freshwater to drink daily, to bathe in and flush our toilets with; but also for growing our veggies and crops; to grow feed for our animals; for healthy riparian and aquatic habitats and ecosystems; for our forests and wild places to sequester carbon dioxide as biomass carbon sinks. But increasingly we are approaching boundaries and limits on the amount of freshwater available and the trade-offs involved in competing uses.

Climate Change Banner drop at London 2012 Games

In an open letter addressed to the international community attending the London 2012 Games, the group Climate Siren outlined why they did the action:

"The 2012 Olympics were a huge inspiration as to how we can come together to overcome challenges and achieve success – at many levels; as participants, as spectators, as competitors, even as a host nation. No doubt the Paralympics will equal or surpass this.

"But these Games can be an inspiration for us to confront the biggest challenge our species has ever faced – perhaps will ever face: The changing climate and the threat it poses to our civilisation’s very existence on this beautiful planet.

'Why is Baillieu funding coal?' demand climate activists

Activists from Quit Coal were able to get a message across this morning: with a banner drop over the main entrance of the Victorian State parliament house. The banner said "'Coal is the single greatest threat to civilisation and all life on our planet' Prof. James Hansen, NASA. Why is Baillieu funding coal?"

Four activists eluded security and were able to climb the scaffolding at the back of parliament house to the roof to drop the banner just after 9am. Two chained themselves on the roof while two more dropped down with the banner on ropes. Nine other people chained themselves on the steps of parliament house.

Protestor Dominic O'Dwyer said from the roof: "We are planning on staying here until the government does something recognising the threat that climate change poses. We would like the government to take the threat of climate change seriously."

Arctic sea ice Extent drops to lowest on record and still shrinking

On August 26 it was announced that arctic sea ice extent this summer has dropped to it's lowest level ever recorded, surpassing the previous record in 2007. And summer sea ice melt still has further to go this season with ice extent usually reaching a minimum area in mid September.

"This is a profound — and profoundly depressing — moment in the history of our planet," said Shaye Wolf, climate science director at the Center for Biological Diversity’s Climate Law Institute. "The sea-ice death spiral, coming during one of the warmest summers in American history, is just one more clear sign of the deepening climate crisis that we ignore at our own peril."

Australia puts the chill on hot July

July 2012 was the hottest month on record for the continental United States. The heat was also felt up into the Canadian prairies, the Arctic and northern Greenland, Northern Africa, Middle East, Central Europe, Russia, Ukraine and the Antarctic Peninsula. But the temperature record fell short due to a few places like Australia which experienced cold temperature anomalies.

Changes in extent and intensity of wildfire linked to Climate change

A new international scientific study lead by a researcher from the University of Utah links extreme fire weather to increasing temperatures and drought driven by climate change.

The study, lead by geography professor Mitchell Power, found that the extent and intensity of wildfires on a continental and global basis is connected to changing temperatures and climate. The study dismissed the theory that population decline was the primary cause for reduced wildfire during the cooler periods in the last 2000 years arguing "climate change was likely more important than indigenous population collapse in driving this decline."

Further subsidies for Victorian coal by Victorian and Federal Governments

Last week Federal Funding for new Victorian coal fired power station was withdrawn. This week the Federal and Victorian Government announced $90 million in funding for 'clean coal' type demonstration programs to justify continued exploitation of Victoria's brown coal resource. Two steps forward, now two steps back.

On Friday Federal energy and Resources Minister Martin Ferguson and his State Minister equivalent, Michael O'Brien, announced $90 million funding support for "advanced lignite technologies". These are supposed 'clean coal' technologies to convert the high carbon intensive content of lignite into a product somewhat less carbon intense, to justify continued reliance and addiction to coal technologies and to even justify development of a processed brown coal export industry.
