Prime Minister Julia Gillard announced that the Government’s carbon tax will not apply to petrol for individual drivers, so that the higher petrol prices will not impact on families or small businesses. If carbon is priced at $25 a tonne, the price of petrol could increase by six cents per litre. Larger businesses may be charged the increased petrol costs, although details of how they will be charged have not yet been released.
The Ningaloo Coast in Western Australia has been listed as a world heritage site by the United Nations. The area, which contains one of the world’s longest near shore reefs, harbours a number of rare marine species including sea turtles and whale sharks. Paul Gamblin from WWF says the listing will afford the reef better protection, and is a great win for campaigners who called for its conservation.
Thousands of people around the nation’s capital cities have rallied at ‘Say Yes’ campaigns in support of the Federal Government’s plan to set a price on carbon pollution. But CEO of the Climate Institute, John Conner, says the rallies are not a simple endorsement of the proposed carbon tax, because Australians also want policies for clean energy and energy efficiency. Details of the Government’s carbon pricing scheme will be finalised in early July before legislation is brought into Parliament in September and fixed carbon pricing is introduced in 2012.
A new report commissioned by the Federal Government has evaluated the potential damage under a worst-case climate change scenario, a sea level rise of 1.1 metres within 90 years. With a massive 85 per cent of Australia’s infrastructure located along the coast, the report found $226 billion worth of assets would be at risk of being damaged or wiped out. The research is intended to warn any future coastal developments to take account of potential sea level rises, and to allow people to adapt and prepare for the consequences of climate change Australia may face.
An Australian study has found the first known negative impact of ocean warming on a fish species in the southern hemisphere. The study, published in Nature Climate Change showed harmful effects on the growth of the banded morwong, an inshore species of fish from south-east Australia and New Zealand. Growth rates of the fish actually increased with mild rises in water temperature, but at average annual water temperatures of above around 17°C the fish suffered a decline in growth, thought to be caused by physiological stress.
Japanese researchers will be scanning parts of the Great Barrier Reef with a deep-sea robot, able to dive to 1,000 metres. The robot will take video recordings in high definition and record data of sea floor conditions. Not much is currently known about the sea floor of the Great Barrier Reef, but it is hoped this study will improve knowledge about the animals, how they have evolved, and any links to a possible Antarctic current.
Earth Hour 2011 saw ten million Australians and a record 134 countries and territories around the globe take part. Co-founder Andy Ridley said Earth Hour is not really about the amount of power saved during the hour, but about what can happen when people work together. This year organisers asked that people also commit to an environmental action that they will continue throughout the year.
