The document provides an overview of an article that introduces the concept of the Anthropocene, a proposed new geological epoch defined by human influence on Earth systems. It summarizes the article's discussion of how human impacts have grown since the Industrial Revolution and accelerated after WWII. The authors assess evidence that human activity is the dominant influence on the planet and consider implications and possible paths forward, including continued growth, mitigation efforts, or geoengineering. They warn that the next few decades will be critical in determining the trajectory of the Anthropocene.

“The Anthropocene:
Are Humans Now Overwhelming
the Great Forces of Nature?”

The article has become a classic and has taken on a large
following. The notion of the Anthropocene has stuck.

5. How did we get there
from here?

6. What are the implications?
Shanghai, 2007 (National Geographic)4/30/2014 6

7. From One Earth to One World:
This phrase, the subtitle of the Brundtland
Commission Report, Our Common Future,
implies that:
• The two images of Earth, one rooted in nature
and the other in global economic society,
must be reconciled.
• This broadly defines the challenge of World
Sustainability.

8. The abstract from the original:
4/30/2014 8

9. Try another definition:
"A period marked by a regime change in the activity of
industrial societies which began at the turn of the
nineteenth century and which has caused global
disruptions in the Earth System on a scale unprecedented
in human history: climate change, biodiversity loss,
pollution of the sea, land and air, resources depredation,
land cover denudation, radical transformation of the
ecumene, among others. These changes command a
major realignment of our consciousness and
worldviews, and call for different ways to inhabit the
Earth.“
(Emphasis added; source, A Cartography of the Anthropocene, viewed on 9/9/2012)

10. The article’s first two paragraphs
frame the challenge.
• Human-induced change raises disturbing questions about the
future of Earth and the environmental services that support
human civilization.
• They ask: Has the Earth left the benign interglacial state of the
Holocene to enter a new era of Earth history, the
Anthropocene?
• They assert: “The Earth is rapidly moving into a less
biologically diverse, less forested, much warmer, and probably
wetter and stormier state.”
• This “represents a profound shift in the relationship between
humans and the rest of nature.”

11. Before the Anthropocene:
• The Agricultural Revolution began 10,000 to 12,000
years ago. Humans domesticated animals and plants,
cleared forests, and discovered fire. Humans did not
yet possess the technology or organization to
dominate nature above a transitory regional level.
• About 10,000 years ago, written language allowed
the “accumulation of knowledge and social learning,”
which the authors describe as “an impressive
catalytic process”.

12. The origins of the Anthropocene I:
The Industrial Era (ca. 1800-1945)
1. The Industrial Revolution
2. The widespread use of coal (fossil fuels)
3. The expansion of economic society
4. Human population expands from about 750
million to about 2.5 billion.
Note the emphasis on economics and not
demography: Population growth follows economic
growth.
4/30/2014 12

13. Note the importance of energy:

14. The Anthropocene II:
The Age of Acceleration
(1945-ca. 2015)
“This first stage of the Anthropocene ended
abruptly around 1945, when the most rapid and
pervasive shift in the human-environment
relationship began.”
This is also the advent of the USA as a world
military, economic, and cultural power.
4/30/2014 14

15. An inflection point starts around
mid-20th century.
The Age of Acceleration starts soon after World
War II, in 1950 with the USA as its epicenter.
This historical observation initiates much of
what unfolds in our course.

17. Examine indicators of
the Anthropocene:

18. See the original report
for indicators.
See especially table 1 and figure 2, page 617 of
the original article on the Anthropocene.

19. Anthropocene III:
Stewards of the Earth (ca. 2015-?)?
“Humankind will remain a major geological force
for many millennia, maybe millions of years, to
come. … Can humanity meet this challenge?”
4/30/2014 19

20. Humanity is becoming aware
by these means:
1. Research, particularly on “interdisciplinary
work on human-environment systems”
2. The Internet as “a global self-organizing
information system”
3. The spread of free and open societies
4. Democratic political systems and the
emergence of civil society.
4/30/2014 20

21. Three paths are open.
1. Business as usual
2. Mitigation
3. Geo-Engineering
We need to examine them and perhaps go
even further, regarding the challenge as an
opportunity.
4/30/2014 21

22. Consider a fourth path:
social ecology
The Institute for Social Ecology considers social
ecology to be:
1. A coherent radical critique of contemporary
social, economic, political, and anti-ecological
trends;
2. A democratic path toward reconstruction based
on the convergence of small-scale, decentralized
communities and bio-regions around
appropriate technology and ethical social
relations. This is called re-inhabitation.
4/30/2014 22

23. The business as usual scenario:
Stated as: “…the institutions and economic system that
have driven the Great Acceleration continue to
dominate human affairs.” This assumes:
1. Human-driven changes will not disrupt the global
economy or societies.
2. Economic society (“market-oriented economic
system”) can adapt adequately.
3. The resources are available to mitigate damage.
4/30/2014 23

24. The risk to business as usual:
“The long-term momentum built into the Earth
System means that by the time humans realize
that a business-as-usual approach may not
work, the world will be committed to further
decades or even centuries of environmental
change. Collapse of modern, globalized society
under uncontrollable environmental change is
one possible outcome.”
4/30/2014 24

25. The authors do not express optimism:
They note that “the Great Acceleration has
considerable momentum and appears to be
accelerating.”
They conclude: “The critical question is
whether the trends of dematerialization and
shifting societal values become strong enough
to trigger a transition of our globalizing society
to a more sustainable one”
4/30/2014 25

26. The mitigation scenario involves:
• Improved technology and social organization
• Wise use of resources
• Control of human and animal population
• Conservation and restoration of the
environment
4/30/2014 26

27. The authors stress dematerialization:
Technology and economic development is
essential. “Over the past several decades rapid
advances in transport, energy, agriculture, and
other sectors have led to a trend of
dematerialization in several advance economies.
The amount and value of economic activity
continue to grow but the amount of physical
material flowing through the economy does
not” (619).
4/30/2014 27

28. Energy is important in the
mitigation scenario.
“In addition to the many opportunities for
energy conservation, numerous technologies ---
from solar thermal and photovoltaic through
nuclear fission and fusion to wind power and
biofuels from forests and crops --- are available
now or are under development to replace fossil
fuels” (619).
4/30/2014 28

29. The geo-engineering scenario:
Essential to this scenario is sequestration of
carbon dioxide in underground reservoirs.
Another technology is the release of aerosols to
reflect the sun’s rays in the stratosphere.
4/30/2014 29

30. A warning about the
geo-engineering scenario:
Geo-engineering carries risks of unintended
consequences and is subject to intense ethical
debate. They warn that the cure could be worse
than the disease.
4/30/2014 30

31. The conclusion issues a warning.
The final paragraph states that the Great
Acceleration is approaching a critical stage.
The authors conclude: “Whatever unfolds,
the next few decades will surely be a tipping
point in the evolution of the Anthropocene.”
What do you think?

32. My expansion on the theme of the
Anthropocene
Anthropocene ==>
Technosphere ==>
Noosphere
4/30/2014 32

33. The article explains the Noosphere:
4/30/2014 33

34. From Anthropocene to Noosphere
The teleology, or end point, of the biosphere
was to provide the physical conditions for the
ultimate destination of evolution, the
transformation of the biosphere into the
noosphere. Just as the biosphere transformed
the earlier geosphere, the noosphere would
transform the biosphere, extending the
culminating destiny of humanity. (From W.
Hayes, The Noosphere.)
4/30/2014 34

35. Vernadsky, Russian geographer and
cosmologist stated in 1929:
“The biosphere is the
cradle of the noosphere.”
4/30/2014 35

36. From Teilhard de Chardin
In 1926, Vernadsky met Teilhard de Chardin, a
paleontologist and a Jesuit priest. Chardin had
speculated about a global transformation, the
noosphere.

37. To be continued!
My intention in this presentation is simply to
connect the Anthropocene to the Technosphere
and then to the Noosphere. This will be
continued later.
