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 …
(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 …

Now the Victorian Election is over, we we must keep our politicians feet to the fire. Strong, early, and competent action against global warming is the only issue in Parliament that really matters if we are concerned for the futures of our families, or indeed, for our species and the majority of life on our …

Australia has a new government. Every month we fail to stop global warming is a month closer to global mass extinction. Still no visible progress towards solution. The graphic above downloaded today shows the current state of sea-ice surrounding the Antarctic continent. Despite what seems to be a cold winter in Victoria, its coverage indicated …

Tropical warming is cutting life-spans of Australian and other rainforest trees in half by robbing them of moisture they need for survival Featured Image: Alexander Schenkin, Author provided (from the article). / I’m fascinated by this pic. Each tree totally controls its air space with little or nothing left to waste (or share), leaving a …

Lystrosaurus
A 2016 article lays out where we were then compared to past extinctions. We are now closer to point of no return. Warming must be stopped! Featured image: Moschorhinus kitchingi with Lystrosaurus. Basal Triassic of South Africa. Lystrosurus was one of the few large animals that survived the Permian-Triassic global mass extinction event anywhere on …
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 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 …
by Joel Makower, 31/01/2022 in GreenBizThe new ‘ROI’ for climate: The ‘risk of inaction’
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 …
Part 4 of David Spratt’s guidebook to events along the road to Hothouse Hell: Overheated tropical forests are turning from carbon sinks into net greenhouse gas emitters. In this part of his narrative, David Spratt leaves the polar regions he discussed in Part 3, to see what is happening to tropical forests (and other habitats). …
Part 3 of David Spratt’s guidebook to events along the road to Hothouse Hell: Collapse of the Greenland Ice Sheet. Continuing from David Spratt’s look in Part 2 of his guidebook at evidence that the West Australian Ice Sheet is beginning to collapse; here, in Part 3 he turns his attention north, to signs that …
Part 2 of David Spratt’s guide-book to events along the road to Hothouse Hell: collapse of the West-Antarctic Ice Sheet This post continues David Spratt’s account of how we humans seem to be passing critical tipping points in the dynamics of Earth’s Climate System initiating the positive feedbacks of runaway global warming to Earth’s Hothouse …
In the last 150 years, greenhouse gases have spiked to never before seen levels. Global masss extinction will result if these are not reversed,.
In this article David Spratt explains how we have embarked on this road to Earth’s Hothouse Hell. Spratt’s story will continue Spratt warns us that more posts will follow in this series. One might relate to the unexpectedly rapid thawing of the Siberian permafrost (H on the map above) that holds at least two times …
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 …
