Anthropocene

Anthrocene or Anthropocene?

Anthropogenic or anthropogenically? Anyway you look at it, you and your billions of fellow anthro-inhabitants are having an impact...

○ ○

Humans and their creations/products/industries/developments/lifestyles/extractions and emissions are having an impact on Planet Earth or, as often called by native people, 'Mother Earth'. 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 (yes, Senator Inhofe, you 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.

1610 or 1964?

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

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.

Paying for the environmental damage they do would render global industries unprofitable overnight: The externalities are massive

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.
