The sentinel lighthouse warns mariners of rocky shores. Climate Sentinel News provides similar warnings to Australians and people everywhere threatened by the growing Climate Emergency.


Rev. 0 – 11/03/2024! 2023 set new planetary extremes as our activities force global temperatures ever higher on the way to mass extinction. 2024 looks even worse! Soon humans will no longer be able to survive in the climate we are forging. My featured image of the state of Earth’s oceans up to February 1 …

If we don’t reverse the climate system’s growing energy imbalance it will soon drive us over the lethal fall into global mass extinction ALL the global climate indicators are at or near all-time records so extreme that by September last year staid climate professionals have called the readings “gobsmackingly bananas.” — a phrase that is …
(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 …
The idea of a ‘tipping point’ is more than academic. Once you trip over it you are on a downhill slide towards Hell at the bottom of the hill Featured image: Shutterstock from the featured article.
An EOS article published today puts exclamation marks around yesterday’s post: “Thawing permafrost in the Arctic warns we are probably crossing several critical tipping points on the road to runaway warming and near-term human extinction“. “The increasing incidence of wildfire in the Arctic is not only thawing permafrost but also changing the entire underlying structure …
Part 6 of David Spratt’s guidebook to events along the road to Hothouse Hell: Burning Siberian tundra, taiga forests and peat soils are all contributing to thawing permafrost and pushing greenhouse gas emissions past an important tipping point Spratt focuses almost exclusively on the consequences of permafrost thawing without much consideration of the overall environment …
Tipping points should be identified early and acted on fast to tackle the climate crisis. Social change needs to be dramatically accelerated. by Damian Carrington, 11/02/2022 in The GuardianIdentify A-ha moments to trigger fast climate action, say UK scientists: Using ‘tipping points’ can unlock the changes needed on energy, food and plastics, analysis shows

Part 7 – concluding David Spratt’s guidebook to events along the road to Hothouse Hell: Have we triggered so many tipping points already that we are already at or past the point of no return? Clearly, we wont know if we have passed the point of no return until it is too late to do …
Part 5 of David Spratt’s guidebook to events along the road to Hothouse Hell: Increasingly frequent and stronger marine heatwaves are bleaching and killing corals, architects of reef ecosystems. Rotting organic matter emits GHGs Coral polyps are the primary architects of the remarkably diverse coral reef ecosystems that border lands and islands in tropical oceans …
If Howard and I are right, we have already passed several tipping points triggering positive feedbacks that will cause global warming to increase exponentially towards a point-of-no return where global mass extinction (including humans) is almost inevitable (he links the same science articles I use in this context). To avoid this end we need to turn the barbecue around to roast the pigs and their wooden-headed puppets first.
If you want a future, it is time to take global warming seriously and totally mobilize to fight the fires driving us towards Hothouse Hell. Bill McKibben, one of America’s most respected environmentalists and a founder of the international 350.org, reports from the northern state of Vermont on the winter that wasn’t. As noted by …

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 …

25/07/2023 (for the last version see 8/07/2023) What’s this article about, and why is the date important? 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, …
