Earth seconds: Evolution did a great job!

La Muse des Géologues du Boulou

When counted in Earth-seconds, our human history is a story of a few minutes or hours.

Counting Earth-seconds, living plants and animals populate the planet since some years, at best since two decades; first they lived in the sea and much later they lived on land as well.
Using the same folded time scale – folded by 31 million – the beginning of microbiological life on our planet dates back hundred to hundred-twenty years from today or up to four billion Earth-seconds ago. That is a century of Earth-years before more developed forms of life could emerge on planet Earth.

Editor’s note

Sapere Aude, the century old call of European enlightenment still is out, listened to and on offer to be listened to. Nowadays, while we humans discovered our terraforming skills, recognized collaterals of our aeon-old activities, and are the main agency of this world, it is time to assume duty of stewardship in a world where dichotomy of ‚culture‘ and ’nature‘ is gone. It’s time to be the ‚first servant of our world‘.

Why citizen geoscience?

What’s Prometheus doing today?: Human Niche & Citizen’s Geoscience: Why „citizen geoscience“ or „citizen earth scientists“ should be a feature of modern geosciences? Why is opportune to…

When ‚geoethics‘ (i) „consists of research and reflection on the values which underpin appropriate behaviours and practices, wherever human activities interact with the Earth system“, and (ii) „deals with the ethical, social and cultural implications of geoscience education, research and practice, and with the social role and responsibility of geoscientists in conducting their activities“ (quote from IAPG’s outline of „geoethics“) then ‚geoethics‘ is as much about citizens as it is about geoscientists, their various lifestyles and different professional conducts, respectively.

IMG_0182Geoscience know-how is firmly knotted into many day-to-day activities of modern societies and the design of contemporary production systems and consumption patterns.

Examples to illustrate this perspective of engineering a human niche are many, such as (i) Civil engineering is about building visible intersections of the geosphere and economic activities; e.g. dredging a waterway, building a bridge or constructing a hydropower plant; (ii) a less visible intersection is the design of production systems and consumption patterns, which couple human activity and the bio-geosphere through fluxes of matter and energy; (iii) urban dwellings may serve as a further example; they are a visible intersection with the bio-geosphere and on they are coupled with the bio-geosphere through massive fluxes of matter and energy; e.g. receiving drinking water and ejecting waste water, receiving electric power or fuels and ejecting heat, receiving food and ejecting manufactured goods that at the end of their life-cycle are discarded or recycled elsewhere on the globe; (iv) as more as technology evolved as more convoluted get the involvement of geosciences, such as renewable energy from the wind and solar, local weather forecast of thunderstorms, sea wave forecast for shipping, or global position systems shielded against solar storms.

Under this perspective, a perspective of an anthropocentric Anthropocene, i.e.; human niche for a global population of billion people, geoethics is a common good that needs citizen involvement.

What was “Hacking the Anthropocene”? (Or, why the Environmental Humanities needs more Feminism)

The Seed Box Blog

by Jennifer Mae Hamilton and Astrida Neimanis

Welcome to the Anthropocene! Although this geological era is still to be officially included in the Chronostratigraphic Chart, members of the Anthropocene expert working group agree that we humans are interfering in planetary systems in consequential and irreversible ways. As a result, many are thinking about the current geological epoch as the Age of Man [sic].

None of this is news. Some have, hopefully, been sobered by the idea of the Anthropocene. The concept raises important questions about the impact of human activity on the earth and offers an apocalyptic image of a planetary future in which the only trace of human existence is a curious and toxic layer of rock and chemical sediment. The flipside of sobriety is, of course, intoxication. And, just as the idea can be humbling or cautionary, it can also lead to celebration of an…
