The Great Barrier Reef is home to some 1,600 species of bony fish, 130 sharks and rays, and turtles, mammals and more. Most have had no population monitoring, meaning we don’t know how well they are faring.
The Grattan Institute has reported that the costs of solar panels have outweighed the benefits by almost A$10 billion in Australia. But the real benefits of cutting greenhouse emissions are much larger.
2C is the officially agreed safe limit for global warming, but a recent expert finds 2C is still in the danger zone.
While Australia has reached a deal on the Renewable Energy Target, there’s no long-term certainty for the sector yet.
Being time-poor makes it harder to be green, says a study which shows that people who work long hours are more likely to fall short on taking real action to address their environmental concerns.
This month Canada revealed its post-2020 climate target as 30% below 2005 levels by 2030. But current policies make it unlikely Canada will achieve the target within the country.
The United Nations is set to decide whether to add the Great Barrier Reef to the List of World Heritage in Danger. But what is the list, and what does it mean for the places that are on it?
Port traffic near the Great Barrier Reef will more than double by 2025, as coal and other exports grow. While major incidents are rare, the chronic toll on the reef itself still remains largely unknown.
Who cares more about environmental issues: people in rich countries, or not-so-rich countries? A survey suggests it’s those in poorer places who are more vulnerable to issues like climate change.
China’s falling coal production suggests the world is waking up to the real cost of coal, calculated as $5.3 trillion in a report released this week.
Countries will take emissions reduction pledges to international climate talks in Paris at the end of this year. Those pledges should also include funds for low-carbon R&D.
There is a way for governments to find out the consensus on global issues such as climate change. But it involves painstaking, complex work, and an end to the adversarial clash of competing ideologies.
With the federal cuts to the renewable energy target, the states are stepping up to fill the gap.
Nuclear power isn’t ‘zero-emission’, as many proponents claim. Factor in uranium mining, power plant construction, and other factors and it has similar emissions to wind power. But that’s still lower than fossil fuels.
Successive plans to curb the sediments, nutrients and pesticides flowing into the waters around the Great Barrier Reef have fallen short, leaving the corals that call the reef home highly vulnerable.
Recent water leaks related to coal seam gas development in New South Wales raise more concerns about the industry’s impact on groundwater.
Recent comments by Federal Minister for the Environment, Greg Hunt, implied that Australia is leading the world in reduction of greenhouse gas emissions per unit of GDP. Is that right?
With the United Nations set to decide on whether to list the Great Barrier Reef as officially in danger, we look at the various threats to the reef’s survival, starting with the biggie… climate change.
Nobel Laureates met recently in Hong Kong to sign a memorandum calling for cities to help guard against climate change. As the most creative places on the planet, big cities are the perfect place to meet this challenge.
While the recent emissions reduction auction in Australia was a success, much more needs to be done to build an effective climate policy.
Australia’s cattle industry is keen to begin live exports to the United States. But America is very different to existing live export markets such as Indonesia, making the move much more ethically fraught.
Is nuclear power worth it? No, says Mark Diesendorf – it’s never been a major world energy force, it has caused huge accidents, and its greenhouse emissions are higher than many people realise.
This year’s federal budget outlined plans for infrastructure in northern Australia, but it will need to do more than build roads and rail to sustainably develop the north.
A large new national park might sound like the best way to protect the critically endangered Leadbeater’s possum. But it won’t do anything to save possums from the major threat of bushfire.
