The Extinction Rebellion begins in Australia

Today saw the start of the Extinction Rebellion (XR) movement in Australia. In Melbourne, a crowd of around 150 gathered in Treasury Place to deliver a Climate Emergency Declaration to a government building. They marched in protest against both the state and federal governments, led by a group of “climate guardians” dressed in angel costumes, …

Could Prime Minister Morrison really make anything worse?

Events have overtaken the article I posted earlier today.  The latest leadership challenge spectacle in Australian politics has delivered the top job in the conservative Liberal/National government to neither the incumbent Malcolm Turnbull nor the challenger Peter Dutton. It turns out the new Prime Minister is Scott Morrison. Turnbull was supposedly a moderate out of …

The Paris Agreement was a sham anyway

Trump’s decision to withdraw the US from the Paris Agreement has been condemned by a surprisingly united chorus of political and corporate elites. The mainstream media narrative is that the world was progressing toward solving climate change, and now only Trump is standing in the way. But this narrative doesn’t make sense. Why are the …

Global warming is already dangerous

“Over the bleached bones and jumbled residues of numerous civilizations are written the pathetic words: ‘Too late.’” – Martin Luther King Jr. I’ve been reading up on what the latest climate science says about where we are and where we’re heading, and decided the best way to present the information is in the following table. …

IPCC AR5: global warming more evident than ever

Last week, the Intergovernmental Panel on Climate Change (IPCC) released the first (and primary) instalment of its Fifth Assessment Report (AR5). Its key conclusions include: The Earth is accumulating heat. Heat-trapping greenhouse gases are rising: Atmospheric levels of carbon dioxide (CO2), methane, and nitrous oxide have reached levels unprecedented in at least 800,000 years because …

The Australian Government’s independent Climate Change Authority (CCA) is conducting a Caps and Targets Review this year. In this series I will explain why the review is important, outline what I think its recommendations should be, and attempt to deconstruct everything I believe is wrong with the Government’s climate policies and its underlying flawed beliefs …

Doha climate talks: Island states stand up for ambition

“We have not seen concrete progress on the issues that are important to ensuring the survival of all our members. How many conferences do we have to endure where we go back to our countries and say, ‘next year we will increase ambition to reduce emissions, next year we will see finance, next year we …

Arctic sea ice minimum: A planetary emergency

The news that Arctic sea ice is in meltdown is being treated as merely one news item among many, even though it threatens to set off a chain of tipping points affecting all of humanity and life on Earth. I’m reminded of how the iceberg warnings sent to the Titanic by other ships were interspersed …

Arctic sea ice in a death spiral

Source: International Arctic Research Center As Australian politicians fiddle with the details of an extremely insufficient climate change policy, I’ve been watching Arctic sea ice news with increasing dismay. Summer sea ice in the Arctic is fast melting away, accelerated by amplifying feedbacks in what has been called a “death spiral”. The disappearance of Arctic …

Is Greenland close to a climate tipping point?

Recent findings suggest climate change in Greenland may be approaching a tipping point, beyond which amplifying feedbacks could lead (probably over centuries) to complete melting of the ice sheet, raising sea level by about 7 meters. In June, a team of glaciologists led by Jason Box predicted that we would see melting across 100% of …
