Dangerous tipping points threaten the stability of several of Earth’s natural climate-controlling systems. Conclusion: warming of 1.5oC is not safe. Possible to protect humans from dangerous animals without killing them. Tanzania accused of apartheid by its own people. Tips on tipping points Those who say, ‘Humans have always polluted their environment, there’s nothing new in Continue reading »

Peter Hehir, in his article “Good science has no bias”, asserts that climate scientists should not, and will not, participate in the climate debate. Before reviewing Peter’s reasoning, it would be helpful to outline the current situation. Climate scientists are overwhelmingly in agreement that atmospheric pollution from the emission of greenhouse gases is the prime Continue reading »
The recently published book 'Nuclear is not the answer' by Prof. M.V. Ramana at the University of British Columbia provides a comprehensive and well-researched response to the evolving debate on the relevance of nuclear in our energy mix. Continue reading »
The big battery storage market continues to charge ahead beyond expectations, buoyed by the doubling of planned capacity at what is already Queensland’s biggest battery, and a host of new projects that have taken the sector to levels and dimensions not contemplated even 12 months ago. The first 270 megawatt (MW) and 540 megawatt (MWh) Continue reading »
Climate change will soon be causing an additional 250,000 deaths per year worldwide – children are at particular risk. Only 4% of greenhouse gas emission reduction policies actually reduced emissions. Trust us, we’re doctors About 10 years ago I was reading a research paper in a café near Sydney University and I dropped it on Continue reading »
Australia punches well above its weight when it comes to global fossil carbon emissions. With less than one-third of one percent of the world’s population, we are responsible for about 4.5 percent of fossil carbon emissions globally, and around 80 percent of this comes from our fossil fuel exports. Our nation is thus responsible for Continue reading »
Right now, human population growth is doing something long thought impossible – it’s wavering. It’s now possible global population could peak much earlier than expected, topping 10 billion in the 2060s. Then, it would begin to fall. In wealthier countries, it’s already happening. Japan’s population is falling sharply, with a net loss of 100 people every hour. In Europe, Continue reading »
We need a no-holds-barred attack on corporate power to meet global threats. Humanity cannot — now — avoid troubled and turbulent times. Extreme events will powerfully influence the course ahead, the shape of things to come after the turmoil. They could help or hinder: provide the moral force for urgent action, or preoccupy us with Continue reading »
Climate activists are increasingly using the courts to challenge development approvals and change the law, but so are action delayers. Access to electricity is increasing worldwide, but fossil fuels still dominate electricity production. Climate litigation increasing worldwide Lots of decisions on development proposals by environmental protection authorities, land and environment courts and ministers for the Continue reading »
The scientific advice is clear; the world is tracking towards a climate catastrophe. Shamefully, the Australian government is contributing to the risk of a catastrophe with its support for fossil fuels, especially with its plan for a long-term expansion of gas production. This is a major policy failure. Australia is highly prone to extreme weather Continue reading »
