Kelp is a large seaweed that grows in underwater forests along temperate coasts, sustaining many marine species in turn. The Kelp Highway Hypothesis postulates that Pacific Rim kelp forests and the wealth of fish, mammals and birds that they supported sustained maritime hunter-gatherers spreading into the New World 16,000 years ago. Kelp species play an important role in Chinese, Japanese, and Korean cuisines, and fuelled the production of soda ash in the Scottish Highlands and islands until the industry's collapse in the 19th century, which in turn fuelled emigration to North America and beyond. Charles Darwin wrote of the kelp forests of Tierra del Fuego that "if in any country a [terrestrial] forest was destroyed, I do not believe nearly so many species of animals would perish as would here, from the destruction of the kelp".

What would you do with an extra $550 a week? Australia is set to become the first government to repeal laws that put a price on carbon, and will instead begin directly paying polluters to stop, polluting. Called "Direct Action", Australia's freshly minted conservative government claims the scheme "will reduce Australia’s greenhouse gas emissions and deliver improvements to our environment" Others think not The government also claims that the world is moving away from market based schemes to direct action schemes, but this claim seems uncertain. The government has also moved to close the Climate Change Authority as well as The Clean Energy Finance Corporation What is Direct Action and how does it differ from an emissions trading scheme? Australia's new Prime Minister has had varying points of view on the science of climate change, and the nations recent attendance at the recent climate change talks in Poland offer a glimpse.
It's so hot in Australia they've added a new color to the weather map, a Tasmania-sized deep purple blob 50 degrees or more (123 F). In the USA 2012 was the hottest year ever recorded, smashing through previous records by a healthy margin. 2012 was also the second-worst on a measure called the Climate Extremes Index, surpassed only by 1998. Globally, 2012 is expected to be ranked as the eighth-warmest year on record, with that announcement coming later in the month. "Climate change has had a role in this,” said Jake Crouch, a climate scientist at NOAA.
Yesterday Australia joined many developed nations in putting a price on carbon pollution (fixed at $23/tonne CO2e for three years) (prev). Despite extensive compensation, this moderate economic reform has proved enormously unpopular ("based on a lie") and is expected to be repealed if/when the Federal Opposition are returned to government.
Clean Energy Future. Australia has embarked on a tradeable carbon permit system, covering about 60% of emissions, beginning on 1 July 2012, and mixing in substantial progressive tax reform, putting a line under a very long debate on this matter indeed.
You probably haven't heard of Gina Rinehart. However, she's Australia's richest person and will quite possibly be the world's richest person in a few short years. Her currently limited political activity appears primarily directed at maintaining profitability, avoiding taxes and stopping a price on carbon pollution.
We care about climate change, but we hate the idea of having to do anything about it. Professor of Public Ethics at CAPPE, Clive Hamilton (also author of Requiem for a Species and Affluenza), tells it like it is on climate change policy in Australia.
The Australian Government has committed to a price on carbon from 1 July 2012, prior to a likely full emissions trading scheme within three to five years. The Opposition are outraged, predicting a people's revolt. This should clearly define the next election.
Australia's emissions trading scheme, the "Carbon Pollution Reduction Scheme", is being debated in the Senate today. [more inside]
Bush administration tries to silence NASA's chief climate expert James Hansen from granting interviews about global warming. Meanwhile, a new study by Australian researchers confirms that global sea levels are rising, and may make island nations like Tuvalu and the Maldives uninhabitable by the end of the century.
