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.

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 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 …

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 …
