Caps Review Part 1: The global climate crisis

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 …

Liberals Part 1: Climate denial and deregulation

Almost all of my posts to date have focused on criticizing Australia’s incumbent Labor government. I have written very little about the alternate Liberal/National Coalition government. But as we enter an election year, it is time to examine the Liberals’ policies. Can the Liberals be trusted? To begin with, it is worth noting that the …

2012: The year the world snoozed

The Guardian described 2006 as “The year the world woke up” to climate change. If that’s the case then I guess 2007 was the year we rolled over and went back to sleep. Our alarm clock has continued to ring ever more loudly and clearly, but we just keep on hitting the snooze button – …

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 …

Good Arctic sea ice pic and vid

I’ve already blogged about the record Arctic sea ice melt. The following picture and video further illustrate the point. This graphic from the Australian Conservation Foundation shows what the Arctic melt would look like if Australia was melting: Note that Arctic sea ice volume has declined even more dramatically, with four-fifths disappearing in the 34-year …

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 Tony Abbott a liar, or just plain stupid?

It’s taken them two-and-a-half years, but it looks like the Australian media is finally beginning to cotton on to the blatant dishonesty of Tony Abbott, leader of the Liberal Party and Opposition. His latest mistruths are debunked here. What better time than to recall some highlights from his ever-growing litany of false, misleading, and contradictory …

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 …

Climate change explained in 15 minutes

The other day I found this great TED video where blogger David Roberts explains the significance of increasing degrees of global warming:
