(Rev. 2 – 29/10/2023) Water was the cradle and mother of all life. When the world is too hot it is also the destructor that erases life, as in Derna, Libya on 11/09/2023 Life originated in the sea, dependent on and driven by water based chemistry. When our remote ancestors colonized the land more than …

Notable observations and news items from the Web, with no processing and little in the way of comment. Make of them what you will. Leading up to this September’s extremes https://grist.org/extreme-heat/parts-of-the-world-have-already-grown-too-hot-for-human-survival/ How much are these extremes costing society. For an idea see the following graphic from Scientific American’s blog. Note: this graphic applies only to …
G20 nations broke records in 2022 subsidizing fossil fuel: $1.4 TN in 2022 — more than twice what they have invested in sustainable energy. Clearly, fossil fuel subsidies help the greedy special interests whose carbon emissions are smothering our planet drag us towards mass extinction from the ‘runaway greenhouse‘. Equally clearly, members of governments approving …

News Corp 2 Aug 2023. Caption says it all
Labor Gov’t slashes vital Antarctic research by $25 M while promoting fossil fuel production/export and gifting $200 million to Aussie sport despite the desperate need to understand how unprecedented Antarctic ice and oceanic conditions relate to the climate crisis. Anthony Albanese and the federal Labor government are supposedly concerned to keep Australians safe. Yet, if …

Unedited links etc to climate news sources I trust The Age reports Global warming to cost Australia up to $423 billion over 40 years https://www.theage.com.au/politics/federal/global-warming-to-cost-australia-up-to-423-billion-over-40-years-20230823-p5dyvx.html. This relies on the IPCC’s consistent downplaying of risks in complex dynamical systems that are inherently unpredictable – especially when based on input data that likely did not include observational …

As I write this, the average climate for our WHOLE PLANET is changing so freaking fast we can see visibly measurable changes in the averages from one day to the next! The sudden speed up of changes in …

Carbon release through abrupt permafrost thaw https://www.nature.com/articles/s41561-019-0526-0 Abstract The permafrost zone is expected to be a substantial carbon source to the atmosphere, yet large-scale models currently only simulate gradual changes in seasonally thawed soil. Abrupt thaw will probably occur in <20% of the permafrost zone but could affect half of permafrost carbon through collapsing ground, …

Tipping points toward Hothouse Earth
Northern Hemisphere summer is just starting but heat and wildfire records are already shattered over three continents! Oz + El Niño + summer? The 6 June 2023 Washington Post gives us a bit of a hint of the kinds of conditions humans are likely to face over the next few years if we fail to …

Human activities are triggering self-reinforcing existential climate risks that are growing more lethal with time — our extinction is likely Over the last 200 years prodigious amounts of carbon-based fossil fuels (coal, oil, methane) have been burned to produce waste gases (mostly CO₂) and useful energy to drive the Industrial Revolution, our affluence, our toys, …

Following on from my May 22 post, the Australian Bureau of Meteorology is raising warning flags that the impending El Niño will be the worst yet. There is actually a lot more on the front burner than El Niño. There are signs we may have just crossed a catastrophic ocean tipping point over the last …

Around 90% of the extra heat trapped by the greenhouse layer warms our Ocean to slow rising temperatures. We’ll pay the price. The climate scientist, Bill McKibben reminded me of this fact in his regular newsletter, The Crucial Years, in his 18 May post, Maybe we should have called this planet ‘Ocean’. His post on …
