As a weather attribution study finds that climate change made the weather that drove the devastating Australian fires 30% more likely, Joe Duggan, a science communicator at ANU returned to his project of asking climate scientists how they feel about climate change.
Graham Readfern explains that Duggan was bowled over when he first started the project in 2014. Continue reading Sad, angry, guilty, some hope – climate scientists reveal their feelings
That image is a shot of the earth rising over the moon, photographed on Christmas Eve 1968 from Apollo 8, taken from a 2016 article by Martin Rees, looking at the dawn of the Anthropocene.
He plots two futures, one where we continue to degrade the planet, another more optimistic, where human societies could navigate current threats, achieve a sustainable future, and inaugurate a future more marvellous than what was achieved in the Holocene. He is interested in humans becoming electronic beings, which I’d see as a dystopia. Nevertheless, if humans act together, in the interest of the the broad ecology, including our species as a whole, our future could be bright.
In the real world we take action within nation states, which typically put the nation’s interest, however derived, ahead of other nations or indeed ahead humanity as a whole.
Internationally through the IPCC (Intergovernmental Panel on Climate Change) and the UNFCCC (United Nations Framework Convention on Climate Change) we are offered scenarios on climate change where, at best, the already bad will get worse. In the case of the latest IPCC 1.5°C report we are offered a 50% chance of avoiding the worst of a dangerous climate. Meanwhile, even if ‘successful’ sea levels will continue to rise, the Great Barrier Reef will be devastated, bad weather, droughts, floods and wildfires will get worse.
Unfortunately in Australia we have a government in power that intends to meet it’s commitments through cheap accounting tricks, where its environment department sees emissions continuing to rise through to 2030. Given that we are one of the largest per capita emitters in the OECD, our Paris commitments are exceptionally modest at 26-28% from 2005 levels. Those were initial commitments. A point overlooked is that under the Paris Agreement parties we undertook to ratchet up our commitments post 2020.
So what should Labor do if elected in 2022 to work towards a safe climate and a world were responsible growth and development is possible? What is a climate emergency, and can we respond appropriately? Continue reading Climate emergency – ecological sustainability within planetary boundaries, and a safe climate
This is the final version of a post first published on Thursday 26 September. This version contains additional material, and a considerable amount of the earlier version has been pruned.
I hope to do a specific post on the UN Climate Action Summit in New York. Meanwhile we have a closing media release from the summit. While it tells us that “77 countries committed to cut greenhouse gas emissions to net zero by 2050, [and] while 70 countries announced they will either boost their national action plans by 2020 or have started the process of doing so”, none of the large emitters were included. Matt McDonald, Associate Professor of International Relations at the The University of Queensland, gives a neat summary with lots of links in Highly touted UN climate summit failed to deliver – and Scott Morrison failed to show up.
One success of the Summit was Greta Thunberg’s amazing speech:
In 1988 James Hansen addressed the US Senate warning of the danger of climate change. Ostensibly the world took notice in the Earth Summit at Rio and the establishment of the UNFCCC (UN Framework Convention on Climate Change) which meets in the Conference of Parties for two weeks in early December each year. It gave us the Kyoto Protocol and the Paris Agreement. However, as I indicated in Four graphs that matter in the climate emergency: bonus edition, the effect on rising CO2 emissions is invisible:
This is what was shown for July 01, 2019 at Muana Loa:
This is an updated version earlier post, slightly shorter, where I have deleted some material in favour of new material, especially towards the end, and sharpening some points along the way.

Part of my delay in completing this week’s edition was waiting for something that wasn’t ridiculous to happen. There is plenty like Boris Johnson suspending parliament, and Trump attacking Fox News, and Fox News hitting back.
To be honest, I’ve been knocked a bit askew by the David Spratt’s question At 4°C of warming, would a billion people survive? The answer according to some respected scientists is, in brief, probably not, something less than a billion, and 4°C seems to be where we are heading.
That would mean on average more than a million deaths from global warming each week for the next 90 years. Continue reading Weekly salon 1/9
Again, this post started as an edition of Climate clippings.
Where I ended up after a series of happenings as described below, is concluding that we need a paradigm shift in our climate change aspirations. Instead of trying to limit warming to a point where we can avoid dangerous climate change, we need to recognize that we’ve already gone too far, that the climate is already dangerous, so we should aim to ratchet down GHG concentrations in the atmosphere to attain a safe climate.

At a mid-year meeting of UNFCCC in Bonn this year in June a small group of countries led by Saudi Arabia have put the kybosh on any formal consideration of the IPCC Special Report on 1.5°C in the UNFCCC forum. Continue reading Saudis throw a spanner

With France breaking heat records by nearly 2°C and 1.5 metres of hail fall on Guadalajara in Mexico, Australian blog Lethal Heating has been blogging a storm on the climate emergency. LH selects and republishes three articles per day, adding value by making some available that may be paywalled, and adding a list of links to relevant previously published articles.
Below I’ve linked to some recent articles. Continue reading Climate clippings 232: climate emergency edition

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.
