A lot of the "rock scientists" simply have no sense of timescales shorter than 1 million years
No species lasts in its existing form for 2 billion years.
The serious problems that humanity is facing are in the next 200 years.
Nice try, Rockdoc. There are two working groups on the Subcommission on Quaternary Stratigraphy,
One group working on the subdivision of the Holocene, the other on the determination if the Holocene has ended and when.
There is a political battle going on between Geologists who are loathe to recognize man's impact, and those that recognize man's impact, which has created a deep political polarization within the organization.
The subdivision working group reported first. That is all. Anti-Anthropocene geologists are declaring victory, but whether the Holocene has ended has yet to be determined.
The subdivision working group exceeded their mandate when they stated the Holocene continues in their report.

IUGS ratifies Holocene subdivision
Posted on July 20, 2018 by Martin J. Head
On June 14, 2018, the Executive Committee of the International Union of Geological Sciences (IUGS) ratified the subdivision of the Holocene Series/Epoch as follows:
Lower/Early Holocene Subseries/Subepoch = Greenlandian Stage/Age with a base dated at 11,700 years b2k (before 2000 AD). GSSP = NGRIP2 Greenland ice core.
Middle Holocene Subseries/Subepoch = Northgrippian Stage/Age with a base dated at 8236 years b2k. GSSP = NGRIP1 Greenland ice core.
Upper/Late Holocene Subseries/Subepoch = Meghalayan Stage/Age with a base dated at 4250 years b2k. GSSP = a speleothem (specifically a stalagmite) from Mawmluh Cave, Meghalaya, northeast India.
The above subdivision has no bearing on the Anthropocene, which remains an undefined unit under active investigation by the SQS Anthropocene Working Group.

Working Group on the ‘Anthropocene’
What is the ‘Anthropocene’? – current definition and status
◾The ‘Anthropocene’ is a term widely used since its coining by Paul Crutzen and Eugene Stoermer in 2000 to denote the present time interval, in which many geologically significant conditions and processes are profoundly altered by human activities. These include changes in: erosion and sediment transport associated with a variety of anthropogenic processes, including colonisation, agriculture, urbanisation and global warming. the chemical composition of the atmosphere, oceans and soils, with significant anthropogenic perturbations of the cycles of elements such as carbon, nitrogen, phosphorus and various metals. environmental conditions generated by these perturbations; these include global warming, ocean acidification and spreading oceanic ‘dead zones’. the biosphere both on land and in the sea, as a result of habitat loss, predation, species invasions and the physical and chemical changes noted above.
◾The ‘Anthropocene’ is not a formally defined geological unit within the Geological Time Scale. A proposal to formalise the ‘Anthropocene’ is being developed by the ‘Anthropocene’ Working Group for consideration by the International Commission on Stratigraphy.
◾The ‘Anthropocene’ is currently being considered by the Working Group as a potential geological epoch, i.e. at the same hierarchical level as the Pleistocene and Holocene epochs, with the implication that it is within the Quaternary Period, but that the Holocene has terminated.
◾Broadly, to be accepted as a formal term the ‘Anthropocene’ needs to be (a) scientifically justified (i.e. the ‘geological signal’ currently being produced in strata now forming must be sufficiently large, clear and distinctive) and (b) useful as a formal term to the scientific community. In terms of (b), the currently informal term ‘Anthropocene’ has already proven to be very useful to the global change research community and thus will continue to be used, but it remains to be determined whether formalisation within the Geological Time Scale would make it more useful or broaden its usefulness to other scientific communities, such as the geological community.
◾The ‘Anthropocene’ has emerged as a popular scientific term used by scientists, the scientifically engaged public and the media to designate the period of Earth’s history during which humans have a decisive influence on the state, dynamics and future of the Earth system. It is widely agreed that the Earth is currently in this state.

Rockdoc, you idiot. Did you think I would just let that lie go without coming back with documentation from the Subcommision itself? Everyone already knows you never post the truth, why do you even bother anymore? You have a credibility of -10.
Ten years ago Timothy Lenton spearheaded a scientific paper examining expert assessments on the types and likelihoods of Tipping Elements in the Climate System. A number of top European climate scientists published an update a few days ago, to get a handle on the risk of cascading climate feedbacks propelling the Earth into a hothouse state. They suggest that we are on that path now, and have a decade or two to avoid the worst. I fear that we have already gone over that cliff, and I declare a global climate change emergency to claw back up the rock face to attempt to regain system stability, or face an untenable calamity of biblical proportions.
It may sound like the title of a low budget sci-fi movie, but for planetary scientists, "Hothouse Earth" is a deadly serious concept.
Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.
Even if countries succeed in meeting their CO2 targets, we could still lurch on to this "irreversible pathway".
Their study shows it could happen if global temperatures rise by 2C.
We explore the risk that self-reinforcing feedbacks could push the Earth System toward a planetary threshold that, if crossed, could prevent stabilization of the climate at intermediate temperature rises and cause continued warming on a “Hothouse Earth” pathway even as human emissions are reduced. Crossing the threshold would lead to a much higher global average temperature than any interglacial in the past 1.2 million years and to sea levels significantly higher than at any time in the Holocene. We examine the evidence that such a threshold might exist and where it might be. If the threshold is crossed, the resulting trajectory would likely cause serious disruptions to ecosystems, society, and economies. Collective human action is required to steer the Earth System away from a potential threshold and stabilize it in a habitable interglacial-like state. Such action entails stewardship of the entire Earth System—biosphere, climate, and societies—and could include decarbonization of the global economy, enhancement of biosphere carbon sinks, behavioral changes, technological innovations, new governance arrangements, and transformed social values.

Sail boats, even just running under motor alone, get far better mileage than a powerboat. Unless the powerboat is designed and powered as a displacement only hull.
Twin screws are not so good in the ice. The keel, especially a sailboat keel, provides a lot of protection to the prop and rudder, it deflects the ice.

The Great Dying wiped out at least 90% of the species on Earth due to an abrupt rise in global-average temperature about 252 million years ago. The vast majority of complex life became extinct. Based on information from the most conservative sources available, Earth is headed for a similar or higher global-average temperature in the very near future. The recent and near-future rises in temperature are occurring and will occur at least an order of magnitude faster than the worst of all prior Mass Extinctions. Habitat for human animals is disappearing throughout the world, and abrupt climate change has barely begun. In the near future, habitat for Homo sapiens will be gone. Shortly thereafter, all humans will die.
There is no precedence in planetary history for events unfolding today. As a result, relying on prior events to predict the near future is unwise.

I’m often accused of cherry picking the information in this ever-growing essay. I plead guilty, and explain myself in this essay posted 30 January 2014. My critics tend to focus on me and my lack of standing in the scientific community, to which I respond with the words of John W. Farley: “The scientific case is not dependent on citation of authority, no matter how distinguished the authority may be. The case is dependent upon experimental evidence, logic, and reason.” In other words, stop targeting the messenger.
In other words, near-term extinction of humans was already guaranteed, to the knowledge of Obama and his administration (i.e., the Central Intelligence Agency, which runs the United States and controls presidential power). Even before the dire feedbacks were reported by the scientific community, the administration abandoned climate change as a significant issue because it knew we were done as early as 2009. Rather than shoulder the unenviable task of truth-teller, Obama did as his imperial higher-ups demanded: He lied about collapse, and he lied about climate change. And he still does.

According to a paper published online in the 5 February 2015 issue of Geophysical Research Letters, “underwater volcanoes defy expectations and erupt in bursts rather than a slow pace.”

64 and 65. A study published in the 11 July 2016 online issue of Nature thoroughly documents one of the most profound planetary changes yet to be caused by a warming climate: The distribution of clouds all across Earth has shifted. Specifically, the shift has expanded subtropical dry zones, located between around 20 and 30 degrees latitude in both hemispheres, and also by raising cloud tops. Each of these changes worsens overall planetary warming. According to a story in the Washington Post accompanying the paper’s release, each of these two changes to clouds is a positive feedback to climate change.
Climate change is causing the North Pole’s location to drift, owing to subtle changes in Earth’s rotation that result from the melting of glaciers and ice sheets. The finding suggests that monitoring the position of the pole could become a new tool for tracking global warming.
Computer simulations had suggested that the melting of ice sheets and the consequent rise in sea level could affect the distribution of mass on the Earth’s surface. This would in turn cause the Earth’s axis to shift, an effect that has been confirmed by measurements of the positions of the poles.
Now, Jianli Chen of the University of Texas at Austin and colleagues have shown that melting due to our greenhouse-gas emissions is making its own contribution to the shift.
The wobble in Earth’s axis of rotation is a combination of two major components, each with its own cause. One is called the Chandler wobble and is thought to arise because the Earth is not rigid. Another is the annual wobble, related to Earth’s orbit around the sun.
