What is Wilderness? (Part 8)

By

“Wilderness is mainly in the mind’s eye – to be a stranger in a strange land for a fraction of a second and create an other world where what is familiar and drab and safe is fleetingly unrecognisable yet beckons like a siren’s song. A place like home yet a place like no other.”

Divergent Climate Histories for East and West Antarctica Over 14 Million Years

By

There is an interesting News Focus story in this week’s Science journal, that helps to confirm the different climate histrories for the East and West Antarctic ice sheets – a phenomenon that persists in modern times:

ANTARCTICA: Freeze-Dried Findings Support a Tale of Two Ancient Climates

A surprising cache of ancient plant material adds evidence for divergent climate histories of the East and West Antarctic ice sheets over the past 14 million years

Excerpt: These findings appear to be contradictory at first glance, but in fact they buttress an evolving view among scientists that the two major features of the continent, the western and eastern ice sheets, have experienced vastly different climate histories. Data from the Dry Valleys reveals an East Antarctic Ice Sheet that is high, dry, cold, and stable, at least in its central area. And the ANDRILL cores suggest a more volatile West Antarctic Ice Sheet that is subject to the changing temperatures of the sea in which it wades. “It reaffirms the fragility of the West Antarctic Ice Sheet [WAIS] and the stability of the central part of the East Antarctic Ice Sheet,” says Peter Barrett, a sedimentologist at the Victoria University of Wellington (VUW) in New Zealand, who advised the ANDRILL project.

“Why do we love to believe that mankind is a plague upon the Earth? We view anything and everything that happens in nature, no matter how barbaric, bloody, or destructive, as good. Indeed, the word ‘natural’ has no negative connotation at all.

If a volcano like Mt. Pinatubo in the Philippines dumps millions of tons of sulfur into the stratosphere, cooling the Earth for two or three years, this is simply Mother Nature at work. If humans did it, we would call it an environmental catastrophe.”
