Smears on integrity of Polar wildlife scientist a prelude to Arctic Oil Drilling

A misconduct complaint has been filed against the US Interior Department on behalf of an Arctic scientist who has been under investigation since the start of the year. The scientist, Dr. Charles Monnett, PhD, a wildlife biologist with the U.S. Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) formerly known as the Minerals Management Service, has not been told why he is under investigation or what the allegations are against him, although a record of interview from February this year seemed to question his scientific integrity by focussing on a 2006 scientific paper co-written with Jeffrey Gleason - Observations of mortality associated with extended open-water swimming by polar bears in the Alaskan Beaufort Sea.

Tim DeChristopher jailed for two years and fined $10,000 for climate civil disobedience

On July 26, 2011 in the Salt Lake City Federal courthouse Tim DeChristopher was sentenced to two years prison and a $10,000 fine for making false bids as 'Bidder 70' in disrupting auctions of public lands by the US Bureau of Land Management (BLM) in December 2008 in the final days of the Bush Administration. DeChristopher was successful in 22 bids amounting to $1.8million and caused the prices to be bid up on many other parcels in bidding among the oil companies.

DeChristopher even offered an initial payment within two weeks to the BLM, but this was refused. Many of the parcels of land auctioned were subsequently ruled invalid by the Obama Adminstration, which underlines the injustice of this indictment.

Impacts of Climate change on the NSW South Coast and Illawarra Regions

A new report by the Climate Commission says the Illawarra region and South Coast of New South Wales highlights the increasing risks of the impacts of climate change. These impacts include an increase in the likelihood of large and intense fires as temperatures increase, rising sea levels causing coastal flooding of buildings and infrastructure, changing rainfall patterns and more intense storms increasing the dangers of severe flooding, and impacts to the regional biodiversity.

Professor Will Steffen, Climate Commissioner and author of the report, said "The evidence for climate change is overwhelming and clear. This report shows that the NSW South Coast and the Illawarra region are particularly vulnerable to the impacts of a changing climate."

Lethal heat wave hits the United States

Over fourteen hundred maximum temperature records have been broken or tied across the United States so far this July as a heatwave lingers from the mid-western and southern states and expands to encompass the eastern states. High humidity accompanies the high temperatures making the heat further unbearable. Little relief is being found overnight with highest minimum temperatures recorded also breaking new records: with 1,951 new records and 1,421 tied records to 21st July.

Platypus feeling the heat of Climate change

Some of Australia's most iconic animals are feeling the heat of climate change and global warming. Scientists have already reported that Koalas face starvation, extinction due to climate change and now it seems the Platypus is under threat due to increasing summer temperatures.

The video above of a platypus seen feeding mid-afternoon surrounded by half a dozen people watching is unusual. Platypus are generally nocturnal and shy creatures usually glimpsed at dawn feeding in streams and rivers.

Deforestation in Sarawak and Climate Change

A report by Wetlands International in February reported on the Borneo Orangutan Survival website reports "Two thirds of Sarawak's peatlands were until recently covered by thick, biodiversity-rich rainforest. Between 2005-2010 almost 353,000 hectare of the one million hectare peatswamp forests were opened up at high speed; largely for palm oil production. In just 5 years time, almost 10% of all Sarawak's forests and 33% of the peatswamp forests have been cleared. Of this, 65% was for conversion to palm oil production. (2011; Sarvision, Impact of oil palm plantations on peatland conversion in Sarawak 2005-2010.)

Marcel Silvius from Wetlands International said: "As the timber resource has been depleted the timber companies are now engaging in the oil palm business, completing the annihilation of Sarawak's peat swamp forests."

Conservationists arrested protesting logging in Tasmania and Sarawak by Malaysian Company Ta Ann

Conservationists have today participated in a protest on Hobart's wharf, where a vessel is being loaded for the Malaysian logging company Ta Ann. The protest highlights the ongoing loss of high conservation value temperate forests in Tasmania and the rapacious logging of tropical rainforests of Borneo and destructon of habitat for Orangutan and dispossession of the indigenous Penan people from their ancestral forests and lands.

"Four conservationists have attached themselves to the vessel, we are participating in today's non violent protest to highlight the ongoing loss of high conservation value forests," Huon Valley Environment Centre's Jenny Weber said.

Forests play a major role as carbon sink say scientists

The world's forests remove over one quarter of current annual human carbon emissions from the atmosphere each year, the equivalent of about 2.4 billion tonnes of carbon according to the latest published scientific research. An international team of scientists, including from the US Forests Service and the Australian CSIRO, have quantified the greenhouse gas carbon sink provided by the world's tropical, temperate and boreal forests.

"This is really a timely breakthrough with which we can now clearly demonstrate how forests and changes in landscape such as wildfire or forest regrowth impact the removal or release of atmospheric carbon dioxide (CO2)," says Dr Pep Canadell, CSIRO co-author of the paper: A Large and Persistent Carbon Sink in the World's Forests. "What this research tells us is that forests play a much larger role as carbon sinks as a result of tree growth and forest expansion."

4 Degrees or more? - Science into Policy: Securing a Clean Energy Future for Australia - speech by Greg Combet

In an early morning session on Thursday the Minister for Climate Change and Energy Efficiency, Greg Combet, addressed the Four degrees or more? conference and spoke on the scientific imperatives driving the Government to price carbon and outlined the Government's carbon pricing policy and addressed some of the consequences of that policy for science and innovation.

Despite the policy failing to match the emissions reductions that are needed to close the Global Emissions Gap to limit temperatures to 1.5 to 2 degrees Celsius of global warming, most of those present saw the policy as necessary first steps and were impressed with the multifaceted comprehensive features which will help to decarbonise the economy and drive innovation towards clean energy to adapt to the impacts of climate change.

Here is a transcript of his full speech.

4 Degrees or More? Climate Change: The Critical Decade - a speech by Professor Hans Joachim Schellnhuber

This was the 1st keynote address to the Four degrees or more? conference Australia in a hot world which is currently meeting in Melbourne. After a day and a half of listening to climate scientists detailing the present climate impacts and future projections, understandably I, and many others, felt a little depressed.

But most of these scientists and other delegates are possessed of a human optimism that the challenge can be overcome. That human society has the technical and engineering capability to avoiding a 4 degree or higher world, to limit global warming to 2 degrees celsius as agreed to in Copenhagen in 2009 and affirmed in Cancun in 2010.
