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!

Mass extinctions and climate change: why the speed of rising greenhouse gases matters
[G]reenhouse gases are rising faster than at any time since the demise of dinosaurs, and possibly even earlier. According to research published in Nature Geoscience this week, carbon dioxide (CO₂) is being added to the atmosphere at least ten times faster than during a major warming event about 50 million years ago.
We have emitted almost 600 billion tonnes of carbon since the beginning of the Industrial Revolution, and atmospheric CO₂ concentrations are now increasing at a rate of 3 parts per million (ppm) per year.
With increasing CO₂ levels, temperatures and ocean acidification also rise, and it is an open question how ecosystems are going to cope under such rapid change.

Considers the grim Apocalyptic Horsemen of too many people and too much consumption in a world approaching runaway global warming
by Corey J. A. Bradshaw, et al., 13/01/2021 in The Conversation
Worried about Earth’s future? Well, the outlook is worse than even scientists can grasp
Anyone with even a passing interest in the global environment knows all is not well. But just how bad is the situation? Our new paper shows the outlook for life on Earth is more dire than is generally understood.
The research published today reviews more than 150 studies to produce a stark summary of the state of the natural world. We outline the likely future trends in biodiversity decline, mass extinction, climate disruption and planetary toxification. We clarify the gravity of the human predicament and provide a timely snapshot of the crises that must be addressed now.
The problems, all tied to human consumption and population growth, will almost certainly worsen over coming decades. The damage will be felt for centuries and threatens the survival of all species, including our own.

The Apocalyptic horseman of ecosystem collapse is already thundering through Australia’s native ecosystems. His friends aren’t far behind
by Dana M Bergstrom et al., 29/02/2022 in The Conversation
‘Existential threat to our survival’: see the 19 Australian ecosystems already collapsing
In 1992, 1,700 scientists warned that human beings and the natural world were “on a collision course”. Seventeen years later, scientists described planetary boundaries within which humans and other life could have a “safe space to operate”. These are environmental thresholds, such as the amount of carbon dioxide in the atmosphere and changes in land use.
Crossing such boundaries was considered a risk that would cause environmental changes so profound, they genuinely posed an existential threat to humanity.
This grave reality is what our major research paper, published today, confronts.

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
by Caitlin Moore et al., 25/03/2022 in The Conversation
From rainforests to savannas, ecosystems on land absorb almost 30% of the carbon dioxide human activities release into the atmosphere. These ecosystems are critical to stop the planet warming beyond 1.5℃ this century – but climate change may be weakening their capacity to offset global emissions.
This is a key issue that OzFlux, a research network from Australia and Aotearoa New Zealand, has been investigating for the past 20 years….
The biggest absorbers of atmospheric carbon dioxide in Australia are savannas and temperate forests…. as effects of climate change intensify, ecosystems such as these are at risk of reaching tipping points of collapse.

Thanks to 100 years of extracting burning fossil fuels, the human population has expanded to exploit and control the resources of essentially the entire surface of our planet.
We live on the surface of a sphere of finite size with a fixed surface area, but population growth is almost always exponential (i.e., growth is by multiplication from one generation to the next, rather than addition) — until all the resources are used up. This situation is called ecological overshoot when resources are consumed faster than our world can replace them.
As long as people try to carry on with business as usual the situation gets worse and worse until populations begin to collapse from system breakdown, starvation and disorder in what can become an Apocalypse when the four horsemen come out to play. These situations have occurred locally throughout human history (e.g., in the 14th Century when the Black Death overcame Europe), but now we face a situation that is even more dire.
Not only have we over stretched our limited resources, but the greenhouse gas emissions from our 100-year long frenzy to burn millions of years accumulation of fossil organic carbon has so changed the composition of our planet’s atmosphere that so more solar energy is captured to significantly raise the average temperature of the whole world. In turn, this extra heat has caused changes in the polar regions to capture still more heat — we are now crossing tipping points that lead towards runaway global warming and mass extinction. See my series of posts about David Spratt’s articles on this topic in Climate Code Red for an array of evidence that these tipping points are real.
David Shearman’s article in the political news blog, “The Hill”, featured here, shows a remarkably clear understanding of the ecological aspects of the current apocalyptic crisis I have outlined above. We need to stop the Apocalypse NOW by stopping runaway global warming.
by David Shearman, 21/03/2022 in The Hill
Climate change and loss of biodiversity are the terrible twins working together to threaten human existence. Unfortunately, their wicked problems are accompanied by two equally important drivers of calamity —population and economic growth. These four horsemen gallop in unison and must be considered together.

If it took a much smaller (there were only 3 billion when I was born), and more ignorant population of humans more than 100 years of the industrial revolution using relatively primitive technology to stuff up our atmosphere. If it isn’t already too late….. Given our present population of 8 billion; vastly greater understanding of physics, geology, biology and many other kinds of science; combined with our vastly advanced and powerful technologies we should be able to work out how to recapture our excess emissions and safely put them back into the ground so the Earth can begin to cool.
However, as Shearman’s article shows, society will have to assemble, organize and mobilize a monumentally large and coordinated “global war effort” to have any hope of doing what is needed to avoid total mass extinction and ensure our species’ survival into the future.
In Australia our present LNP COALition Government has made it clear that they will do everything they can to keep shoveling Australian coal on the fire to support and further extend economic growth and business as usual until the very end. Our first step in organizing the war effort to escape the horsemen of the apocalypse must be to replace these puppets of the fossil fuel special interests headed up by Scotty from Marketing.
It seems to taken the clear thinking of Greta Thunberg, a 16 year-old girl who concluded school was pointless as long as humans continued their blind ‘business as usual’ rush towards extinction.
In other words, wake up! smell the smoke! see the grimly frightful reality, and fight the fire that is burning up our only planet so we can give our offspring a hopeful future. This is the only issue that matters. Even the IPCC’s hyperconservative Sixth Assessment WG2 Report that looks at climate change’s global and regional impacts on ecosystems, biodiversity, and human communities makes it clear we are headed for climate catastrophe if we don’t stop the warming process.
Scott Morrison and his troop of wooden-headed puppets are doing essentially nothing to organize effective action against the warming. In fact all they doing is rearranging the furniture in the burning house to be incinerated along with anything and everyone we may care about.
In Greta’s words, “even a small child can understand [this]”. People hope for their children’s futures. She doesn’t want your hopium. She wants you to rationally panic enough to wake up, pay attention to reality, and fight the fire…. so our offspring can have some hope for their future. Vote Climate One’s Traffic Light Voting System will help you use your preferential votes wisely on behalf of our offsprings’ future.
