Human-caused climate disruption worsening at accelerating rate...
In an article this summer in the Proceedings of the National Academy of Sciences, 16 climate scientists from around the world argued that the planet may be much closer than previously realized to locking in what they call a “hothouse” trajectory—warming of 4C or 5C (7F or 9F), “with serious challenges for the viability of human societies.”
Jem Bendell, a professor at the University of Cumbria who popularized the term "deep adaptation", calls it a mix of physical changes—pulling back from the coast, closing climate-exposed industrial facilities, planning for food rationing, letting landscapes return to their natural state—with cultural shifts, including “giving up expectations for certain types of consumption” and learning to rely more on the people around us.
“The evidence before us suggests that we are set for disruptive and uncontrollable levels of climate change, bringing starvation, destruction, migration, disease and war,” he wrote in a paper he posted on his blog in July after an academic journal refused to publish it. “We need to appreciate what kind of adaptation is possible.”
Ethics of Human impacts on the Environment
- by Rika Preisera, Laura M.Pereira, Reinette O. Biggs
The “Anthropocene” demands new forms of engagement and responses to achieve sustainability, but different fields suggest quite different approaches.
We set out four perspectives that we argue have fundamentally different framings of the “problem” of the Anthropocene, and consequently point to very different responses to achieving sustainability.
These four fields include: the eco-modernist perspective, the planetary stewardship paradigm, the pathways to sustainability approach, and the critical post-humanist paradigm.
We suggest that a deeper underlying framing which can help integrate aspects of these four perspectives is an understanding of the “Anthropocene as responsibility”.
We argue that from this perspective it becomes possible to engage with an ethics of responsibility that comes with being human and acting on the planet, in the face of an uncertain and unknowable future.
Introduction
A recent spate of articles has appeared in social media and through other popular channels about the diversely understood concept of the “Anthropocene” (Chin et al., 2016).
Proposed by Paul Crutzen as a new “human-dominated, geological epoch” (Crutzen, 2002), the Earth System Science community increasingly accepts the notion of the “Anthropocene”, and Maslin and Lewis (2015:111) argue “the evidence for humans being a major geological power has been accepted and the paradigm shift has occurred”...there has been an enriching debate within other fields as to the usefulness of this term (Brondizio et al., 2016; Lövbrand et al., 2015). Much of the debate specifically centers on what the concept of the Anthropocene implies in terms of actions needed to reshape human interactions with the Earth System in order to achieve environmental and social sustainability, and more controversially whether it could be possible to conceptualize of a “good” Anthropocene (Bennett et al., 2016).

"A recent report in March 2016 by the Center for American Progress Action Fund shows that more than six out of every 10 Americans are represented by someone in Congress who denies the reality of Anthropogenic Climate Disruption (sometimes referred to as ACD or AGW as in anthropogenic global warming and CAGW - catastrophic anthropogenic global warming). According to the report, 59 percent of the Republican House caucus and an amazing 70 percent of the Republicans in the Senate deny ACD is real. The report also reveals that, according to the US Census, 202,803,591 Americans are represented by an ACD denier."
"The general public is way ahead of Congress — a recent poll found that 76 percent of Americans said they believed global climate change is occurring, including 59 percent of Republicans... and nationally 67 percent support President Obama’s plan to regulate power plants to cut carbon emissions."

Anyway you look at these self-centered words, you and your billions of fellow 'anthro-inhabitants' (planet citizens) are having an unprecedented human impact on Earth's ecology...
When GreenPolicy began at Green Institute, one of our advisors was Bill McKibben, author of "End of Nature". Our point of view brought a larger-than-self perspective, recognizing the dawning and daunting fact that humans had entered a new age, one where we could no longer speak of nature as 'apart' from humanity, where writers and poets would speak of nature as distinct and separate force 'beyond' us all.
The "End of Nature" focused on this new deep reality, where we become aware of our responsibilities for what we have created and, as many societies and cultures and 'good books' have spoken of throughout history, the need to learn and re-learn, generation to generation, the ancient wisdom of 'what goes around comes around' and we will, for good or bad, 'reap what is sown.'
- "Whatever we once thought Nature was — wildness, God, a simple place free from human thumbprints, or an intricate machinery sustaining life on Earth — we have now given it a kick that will change it forever. Humanity has stepped across a threshold. In his free-ranging and provocative book, Bill McKibben explores the philosophies and technologies that have brought us here, and he shows how final a crossing we have made."
- — James Gleick, author of Chaos
- "Bill McKibben's The End of Nature deals with humanity's effect on our natural environment the same way that Jonathan Schell's Fate of the Earth presented the harsh facts of the potential nuclear destruction of life. Both books left me better informed, deeply saddened and wondering if the human species has too much natural ability to dominate (each other and our environment) without the wisdom to use such abilities for the promotion of life."

Humans and their creations/products/industries/developments/lifestyles/extractions and emissions are having a profound impact on the planet, an impact science is beginning to measure and assess. As it is, the human species no longer stands 'outside' the forces of nature (if we ever did) but rather we are now impacting and changing the patterns and dynamics of nature going forward.
... On climate humans are impacting ... on agriculture, oceans, air and water, forests and fisheries, species and varieties ... food chains beginning with the least of creatures (phytoplankton and die-offs) to the large, recognizably endangered mammals ... the modern, industrial activities of humankind are shifting the geologic era in which we live. Anthro-genetics drive us, so to speak, and we will continue to shift future dynamics of nature, changing systems over time as we develop and populations surge. The extent of humanity's impact on the planet is only now beginning to be measured, with baseline data and science surveying the extent and depth of change -- and the resulting impacts on natural systems are sending flashing, warning signals. The evidence is strong and, apart from those in denial, the evidence is resonating strongly, suggesting it is time to act to sustain the biosphere and environmental systems on which our quality of life depends.

Time is divided by geologists according to marked shifts in Earth’s state. Recent global environmental changes suggest that Earth may have entered a new human-dominated geological epoch, the Anthropocene. Here we review the historical genesis of the idea and assess anthropogenic signatures in the geological record against the formal requirements for the recognition of a new epoch. The evidence suggests that of the various proposed dates two do appear to conform to the criteria to mark the beginning of the Anthropocene: 1610 and 1964. The formal establishment of an Anthropocene Epoch would mark a fundamental change in the relationship between humans and the Earth system.

Back to the Anthrocene
In 1992, the science writer Andrew Revkin – in his book Global Warming: Understanding the Forecast – coined the term “Anthrocene” to describe a new geological era dominated by the actions of humans. Slideshare
More recently, he has quoted from his book: “We are entering an age that might someday be referred to as, say, the Anthrocene. After all, it is a geological age of our own making. The challenge now is to find a way to act that will make geologists of the future look upon this age as a remarkable time, a time in which a species began to take into account the long-term impact of its actions.” It now appears that like all respectable geological eras, the Anthrocene will be clearly identifiable as a distinct transition in the stratigraphy of the rocks that will make up that future world.
Over the past 200 years, the oceans have absorbed about half of the Carbon dioxide released into the atmosphere as a by-product of burning fossil fuels such as oil and gas. Researcher’s form the National Oceanic and Atmospheric Administration in the US have been monitoring the acidifying effect that this additional Carbon dioxide is having on the oceans, and have found a detectable decline in pH. Studies by other groups indicate that even small changes in pH have detrimental consequences on species that build their shells out of calcium carbonate, and particularly those in cold water ecosystems, which appear to be sensitive to levels of acidification that could occur in the oceans over the next few decades. These organisms; including sea urchins, cold-water corals, coralline algae, and plankton known as pteropods, provide essential food and habitat to others, their demise could affect entire ocean ecosystems.
The calcite shells of these creatures are also the raw material from which limestone rock is formed, a fact that could result in the beginning of the “Anthrocene” era made visible to future geologists as a stratigraphic boundery, formed by reduced limestone formation, and a period of mass extinction in the oceans. It seems that humans could now be changing the very bed-rock of the planet on which they live; it is a very remarkable time indeed!

- Mass extinctions and ocean acidification
http://link.springer.com/article/10.1007/s00338-008-0381-8#page-1
Primary causes of mass extinctions are linked in various ways to the carbon cycle in general and ocean chemistry in particular with clear association with atmospheric carbon dioxide levels.
The prospect of ocean acidification is potentially the most serious of all predicted outcomes of anthropogenic carbon dioxide increase.
Acidification has the potential to trigger a sixth mass extinction event and to do so independently of anthropogenic extinctions that are currently taking place.

Natural Capital & Externalities
* http://en.wikipedia.org/wiki/Externality
* https://www.greenpolicy360.net/w/Category:Externalities
Grist -- grist for thought... (2013) -- The notion of “externalities” has become familiar in environmental circles. It refers to costs imposed by businesses that are not paid for by those businesses. For instance, industrial processes can put pollutants in the air that increase public health costs, but the public, not the polluting businesses, picks up the tab. In this way, businesses privatize profits and publicize costs.
If we take the idea seriously, not just as an accounting phenomenon but as a deep description of current human practices, its implications are positively revolutionary.
[Begin by reviewing] a Natural Capital & Externalities Report conducted by environmental consultancy Trucost on behalf of The Economics of Ecosystems and Biodiversity (TEEB) program sponsored by United Nations Environmental Program. TEEB asked Trucost to tally up the total “unpriced natural capital” consumed by the world’s top industrial sectors. (“Natural capital” refers to ecological materials and services like, say, clean water or a stable atmosphere; “unpriced” means that businesses don’t pay to consume them.)
It’s a huge task; obviously, doing it required a specific methodology that built in a series of assumptions. (Plenty of details in the report.) But it serves as an important signpost pointing the way to the truth about externalities.
Here’s how those costs break down:
The majority of unpriced natural capital costs are from greenhouse gas emissions (38%), followed by water use (25%), land use (24%), air pollution (7%), land and water pollution (5%), and waste (1%).
So how much is that costing us? Trucost’s headline results are fairly stunning.
First, the total unpriced natural capital consumed by the more than 1,000 “global primary production and primary processing region-sectors” amounts to $7.3 trillion a year — 13 percent of 2009 global GDP.
Second... Surprising no one, coal is the enemy of the human race. Trucost compiled rankings, both of the top environmental impacts and of the top industrial culprits.
The biggest single environmental cost? Greenhouse gases from coal burning in China. The fifth biggest? Greenhouse gases from coal burning in North America.
Trucost’s third big finding is the coup de grace. Of the top 20 region-sectors ranked by environmental impacts, none would be profitable if environmental costs were fully integrated. Ponder that for a moment: None of the world’s top industrial sectors would be profitable if they were paying their full freight. Zero.
Coal power generation in Eastern Asia, which generates revenues of $443.1bn, has a natural capital cost of $452.8bn (that's unpriced natural capital – the report already takes into account the various ways in which industries are forced to price in their externalities), largely due to greenhouse gases. Cattle ranching in South America, with revenues of $16.6bn, has capital cost of $353.8bn, due to the unpriced cost of land use. And so on.
You can quibble the figures – and doubtless many will – but what is clear is they are large. Really, really large. Many of the biggest industries in the world can only exist because they don't have to pay the true environmental cost of what they do. The word "unsustainable" is thrown around too much these days, but it seems to fit here.

"Apparently, impending catastrophe doesn't mean much to some of the United States' wealthiest people. Once again a report has arisen documenting how fossil fuel millionaires pumped more than $100 million into Republican presidential super PACs last year.

- NASA recently released data confirming that February was the warmest month ever measured globally
- A study recently published in the journal Nature Geoscience revealed that carbon emissions are now the highest they have been since the age of dinosaurs, 66 million years ago
- Former NASA scientist James Hansen... published a paper showing that 1 degree Celsius was the scientifically proven point of no return ...
Dozens of countries across Europe and Asia set or tied all-time temperature records
Cities across the United States saw record warm temperatures, in which the 2015-2016 winter was the warmest ever recorded
Winter in the US, according to meteorologists, technically takes place from December through February. This year, that winter was 4.6 degrees Fahrenheit warmer than normal, breaking the previous record, which was set in 1999-2000
Every single US state had winters nearly 2 degrees Fahrenheit warmer than normal and Alaska's winter was an incredible 10.6 degrees Fahrenheit warmer than normal
The New Scientist reported in early March that earth had its highest-ever annual increase in carbon dioxide levels
Meanwhile, melting in Greenland is occurring so intensely and quickly that it is "feeding on itself," according to a recently published study
In North America, millions of acres of forests are struggling and under increasing threat
Another recent study shows that food scarcity caused by ACD would cause at least half a million deaths across the world by 2050, due to food production being impacted by the effects of ACD
The UN recently released a report showing that an ongoing decline of pollinating species now poses a very dire threat to the global food supply
ACD has caused the onslaught of rising sea levels, melting permafrost and other impacts
In Africa, at least 36 million people are facing hunger due to record-high temperatures and drought
Meanwhile in the Arctic, February saw alarming melting of Arctic sea ice, where record-high temperatures brought with them other records -- including record lows for that month's extent and area of Arctic sea ice
In the oceans, things continue to look grim. Recent research shows that coral growth is already being weakened by increasingly acidifying oceans. One-quarter of the carbon dioxide released as a result of human activities is absorbed into the world's oceans, where it alters their chemistry

Rising Temperature a 'Wake-up Call?'
"This has been the saddest research trip of my life," James Cook University professor Terry Hughes, the convener of the National Coral Bleaching Taskforce, said in a press release after the team aerially surveyed almost 2,500 miles of the northern Australia reefs.
Marine Scientists Say: the Undersea Biodiversity Is Dying
Coral bleaching is a modern phenomenon. Over the past 400 years, there's no evidence of bleaching events until the late 20th century. Changing environmental factors like rising sea temperatures can cause the coral to expel their photosynthetic algae, called zooxanthellae, making many turn stark white. Others remain vivid, but have lost the green and brown hues that signal health. Without the symbiotic algae to process sunlight into oxygen and other nutrients, the coral dies.
