The first three months of the year are always difficult for me. It’s hot and humid, and there is a lot of physical work to do. I tend to have annual medical check ups, and our tax return for last year needs to be done by the end of March.
Last year I was in better shape because the blog was broken over the festive season, which allowed me to get a head start. This year the time to get it all sorted is now, so that is what I’m going to have to do.
In this post we find that the 2020 global average surface temperature was 1.25°C hotter than pre-industrial, equal first with 2016, according to The European Copernicus Climate Change Service. This is important for the Great Barrier Reef, because in a little known report in 2013 scientists found that 1.2°C is the warmest compatible with the Reef remaining a coral-dominated system. Focus recently has been on the emergence of annual severe bleaching (ASB) when the affected reefs are effectively dead. Climate change action of the type we are engaged in will only delay the emergence of ASB on average from about 2034 to 2045.Continue reading Temperature pushes Great Barrier Reef to tipping point→
I’m looking for a paradigm shift in the climate change goal from (a) ‘limitation of warming to 1.5°C’, thus escaping the worst of an already dangerous climate, to (b) ‘restoration of a safe climate’.
A safe climate may be described as ecological sustainability within planetary boundaries to include preservation, restoration and enhancement along with responsible economic, social and personal growth and development.
A mouthful perhaps, but the difference between hope and despair.
Looking at existing aspirations (zero net emissions for a 50% chance of limiting warming to 1.5°C) how can we say we will preserve the Great Barrier Reef when scientists tell us that 1.5°C will destroy up to 90% of it?
How can we stop our Pacific neighbours from being swamped by the ocean when we are told that current levels of total greenhouse gases (including methane and all of the ‘Kyoto six’) have an implied warming of 1.75–1.95°C (p13) and longer term equilibrium warming of~2.4°C?
Ask yourself a simple question. Can you give hope to future generations that the Great Barrier Reef will be protected if your policy is to limit warming to 1.5°C when the GBR is already disappearing before our eyes?
How can we set a target of 1.5°C temperature (actually a 50% chance of limiting the increase to that level) when we know that during the Eemian interglacial sea levels rose 6-9 metres with 300ppm of CO2, and we have already broken through the 410 ppm? Continue reading Our beds are burning→
“Climate change is the existential threat to humanity,” the former vice president said. “Unchecked, it is going to actually bake this planet. This is not hyperbole. It’s real. And we have a moral obligation.”
It was 24 June 2010. I was the dentist chair watching Kevin Rudd giving his tearful exit speech, played on the TV in the ceiling. Rudd recounted the achievements of his term. Quite a long list, it was.
To leave aside for a moment whether shunting Rudd was a good idea, and how all that worked out, Brent thinks the reason for our quick turnover of PMs is the Senate and our propensity to elect third party senators.
Currently the Coalition needs three out of five from One Nation’s two, Centre Alliance’s two and Jacqui Lambie’s one.
I pinched that cartoon from the Townsville Bulletin from Facebook, where it was doing the rounds. I think it’s tragic rather than funny, but may go some way to explain why Labor, in Queensland and federally, is over-reacting to the ‘message’ that was sent on Adani, and the prospect of jobs flowing from the resources industry as against climate change and saving the planet. Both Queensland and federal Labor appear to be caving in to coal interests, and both appear to be clueless about the urgency of the climate emergency.

Thailand is happy about being the least miserable country in the world in the in the Bloomberg Misery Index, which is an economic indicator devised by Arthur Okun, and is derived by simply adding the forecasts of unemployment and inflation for the following year.
However, Thailand’s performance in the index is due to the Thai government’s unique way of tallying unemployment. More noteworthy are the performances of Switzerland, Japan and Singapore. For what it’s worth, here are the 10 least miserable: Continue reading Weekly salon 4/5→
The Grattan Institute found that providing tax cuts in the never-never while reducing government expenditure from 24.9% of GDP in 2018-19 to 23.6% during the next decade will necessitate cutting existing programs by more than A$40 billion a year in 2029-30. That should have been the story of the week, but somehow it wasn’t.
While Labor’s 2019 Climate Acton Plan has been completely rewritten compared to the plan they took to the 2016 election the target of 45% emissions reductions (from 2005) by 2030 remains the same. I can’t recall whether they espoused zero emissions by 2050, as they do now, I think it may have been 90%. Their overall strategy is, I think, based on six considerations.
Firstly, Labor acknowledges the cost of doing nothing:
Failure to act on climate change will expose the Australian people and environment to devastating costs for our economy, society, security, health and environment. Experts at the ANU, University of Melbourne and CSIRO estimate failing to keep global warming to below two degrees will eventually cost the average Australian household $14,000 per year.
Secondly, they say:
Labor accepts the science of climate change and endorses the Paris Agreement to keep global warming well below two degrees Celsius as well as a more qualified commitment around a 1.5 degree threshold.
