Cyclone frequency declining while intensity increasing across Australian and Pacific region: CSIRO

New research by CSIRO scientists is showing a trend for fewer tropical cyclones forming off the Western Australian coast, but those that do form may become more intense and potentially destructive. The results apply across the Australian region according to CSIRO in an interview with Dr Debbie Abbs from CSIRO Marine and Atmospheric Research published on December 21, 2011.

Dr Debbie Abbs said there could be a 50 percent reduction in the number of storms in the second half of this century – from 2051-2090 – compared to the period from 1971-2000. The climate model developed by Dr Abbs' team also indicates a distinct shift towards more destructive storms. "Despite a decrease in the number of tropical cyclones, there is a greater risk that a tropical cyclone that forms will be more severe in future," Dr Abbs said. "Even a small increase in cyclone intensity is concerning because of the threat to life, property, industry and agriculture,” said Dr Abbs in a CSIRO media release.

NSW set to hinder wind energy with onerous planning regulations

The NSW Draft planning regulations on wind farms was released on Friday December 23: on the very last working day before Christmas. You don't need to be a cynic to understand the Barrie O'Farrell conservative Government wants to bury news coverage of these draft planning regulations which impose strict limits on wind farm development which are very similar in scope to the draconian Victorian wind farm planning regultions.

"The new wind guidelines introduced today place more rigourous requirements on wind projects than on any other project development in the state." said Lindsay Soutar, national coordinator of the community 100% Renewable campaign. "While coal and coal seam gas get the red carpet, wind power just gets more red tape."

Climate Change: Going Beyond Dangerous - a frank presentation by Professor Kevin Anderson

Listen to this 55 minute webinar (voice presentation with slideshow) by Professor Kevin Anderson, on Climate Change: Going Beyond Dangerous. Professor Anderson is Deputy Director of the Tyndall Centre for Climate Change Research and holds a chair in Energy and Climate Change at Manchester University, and is an advisor to the British Government on climate change (see Wikipedia).

Kevin Anderson explains in simple language what we are facing in our climate future - a four degree world perhaps as soon as 2060 and a 6 to 8 degree world by the end of the century. He is brutally honest and straight forward in his assessments of where we are at with mitigation and the options open for humanity. Climate negotiations have dithered since 1992, and have left no easy options for us. The longer we delay, the more difficult it will be to respond to climate change.
It is only through knowing the dire extent of the situation that we can take the actions necessary to possibly avoid the worst climate impacts.

We Don't Want Coal For Christmas! We want a safe climate.

Eight days ago shoppers in Melbourne CBD were treated to Santa on a seven seater bike and elves asking people to sign a petition for Julia Gillard not to fund the HRL coal gasification power station.

"I’m confused", Santa told onlookers. "I thought nobody wanted coal for Christmas. But then why would Victoria have plans the new coal fired power station HRL? Not to mention a new coal mine in Bacchus Marsh?"

Extreme Weather: Flash flooding kills over 1000, displaces 100,000 in the Philippines

Heavy rain and flash flooding on Friday night and Saturday in the Philippines associated with tropical cyclone Washi, known locally as Sendong, has killed 521 people, with many still missing and unaccounted for, and displaced over 100,000 people. The cities of Cagayan de Oro and Iligan were particularly hard hit.

Tropical Storm Washi dumped on the island of Mindanao more than a month of average rains in just 12 hours. According to weather forecaster Leny Ruiz the records show that storms that follow Washi's track come only once in about 12 years. Officials claim it was one of the most destructive calamities in southern Philippines in recent years and struck areas not used to severe flooding. River flooding was worsened by the high tide.

Update 23 Dec 2011 - Latest report from AFP say that more than 1,000 people dead and another 1,000 missing, with about half a million people affected and 50,000 in evacuation centres.

Wildfires in Canada approaching threshold point due to climate change

The climate is changing in Canada. New research indicates that large areas of Canada are approaching a threshold value where they may experience a rapid increase in the size of wildfires. Both the area burnt down annually and the average size of the fires would increase, write the researchers of the Helmholtz Centre for Environmental Research (UFZ) and the University of Michigan who undertook the research.

Wildfire is expected to increase as a result of climate change in Canada with the majority of wildfires occurring in non-fragmented coniferous forests. Recovery from fire usually takes 20 years. If fires or logging occurrs on a frequent basis, this can cause landscape traps in which the ecology becomes permanently changed. (See example: mountain ash forest landscape trap of Victoria, Australia)

Climate sensitivity - paleoclimate record points towards potential rapid climate change

"The paleoclimate record reveals a more sensitive climate than thought, even as of a few years ago. Limiting human-caused warming to 2 degrees is not sufficient," said NASA climatologist James Hansen at the American Geophysical Union meeting on December 6 2011, "It would be a prescription for disaster."

In a press conference at the American Geophysical Union Fall meeting 2011 in San Fransisco climate scientists James Hansen, Ken Caldeira and Eelco Rohling explained that the climate sensitivity may be greater than previously thought. This has implications particularly for action on climate change mitigation and adaptation with major impacts on sea level rise, ocean acidification and many other areas. The latest proposals and pledges from Durban put the world on the path of 4.3°C of warming by the end of the century.

Is it possible to decouple economic wealth from carbon dioxide emission rates?

Is it possible to decouple economic wealth from carbon dioxide emission rates? Dr Tim Garrett applies basic thermodynamic physics principles to the economics of wealth, carbon emission rates and civilization and comes up with some very disturbing results.

I came across this randomly chasing youtube links. This talk captured in a 3 part video was given at the Pacific Institute for Climate Studies Seminar May 31st, 2010, University of Victoria in Canada, but only recently uploaded to youtube in December 2011. Dr. Tim Garrett is an Associate Professor of Physics in the Department of Atmospheric Sciences, University of Utah, whose main academic work is in cloud physics.

Xstrata Ulan coal mine expansion required to offset greenhouse gas emissions

In a landmark judgement concerning climate change, a judge in the NSW Land and Environment Court has given approval for the expansion of the Xstrata Ulan coal mine near Mudgee in Central western New South Wales, but conditional on the mine offsetting all of its greenhouse gas emissions generated in mining the coal.

The Hunter Environmental Lobby brought an appeal against the $1.2 Billion Ulan West project based upon it's long term impact of exacerbating global anthropogenic climate change, as well as damage to groundwater systems and clearing of critically endangered vegetation communities. The mine expansion proposal includes a 239 hectare open cut mine and approximately 25 square kilometres of additional longwall mining. The environment group were represented by The Environment Defenders Office. (See June 2011 article - Legal Challenge to Xstrata Ulan Coal mine expansion)

In delivering her judgement on the landmark case on Thursday 24 November, Justice Nicola Pain invited the NSW Minister for Planning, Ulan Coal and Hunter Environment Lobby to come to agreement on several environment conditions in the Ulan West project. The Nature Conservation Council of NSW has welcomed the decision saying that this is a landmark legal precedent for coal mines required to offset greenhouse pollution.

Locking in native forest logging: say goodbye to Victorian forest carbon sinks

The Victorian Coalition Government have given a green light to their logging mates by announcing the expansion of native forest logging and locking in to place much longer native forest logging contracts.

In a statement yesterday Agriculture and Food Security Minister National Party MP Peter Walsh released the Timber Industry Action Plan. Under the plan Vicforests would be able to harvest and sell timber through supply agreements of up to 20 years, instead of the current maximum five year period. VicForests will also be given the right to sell timber in a variety of ways, including both timber auctions and other sales arrangements. And contract clauses will be written in to provide compensation if there happens to be a change of government policy in the future (as sometimes happens in a democracy).
