Study predicts imminent irreversible planetary collapse
Date:6/8/2012

Using scientific theories, toy ecosystem modeling and paleontological evidence as a crystal ball, 18 scientists, including one from Simon Fraser University, predict we're on a much worse collision course with Mother Nature than currently thought.

In Approaching a state-shift in Earth's biosphere, a paper just published in Nature, the authors, whose expertise span a multitude of disciplines, suggest our planet's ecosystems are careening towards an imminent, irreversible collapse.

Earth's accelerating loss of biodiversity, its climates' increasingly extreme fluctuations, its ecosystems' growing connectedness and its radically changing total energy budget are precursors to reaching a planetary state threshold or tipping point.

Once that happens, which the authors predict could be reached this century, the planet's ecosystems, as we know them, could irreversibly collapse in the proverbial blink of an eye.

"The last tipping point in Earth's history occurred about 12,000 years ago when the planet went from being in the age of glaciers, which previously lasted 100,000 years, to being in its current interglacial state. Once that tipping point was reached, the most extreme biological changes leading to our current state occurred within only 1,000 years. That's like going from a baby to an adult state in less than a year," explains Arne Mooers. "Importantly, the planet is changing even faster now."

The SFU professor of biodiversity is one of this paper's authors. He stresses, "The odds are very high that the next global state change will be extremely disruptive to our civilizations. Remember, we went from being hunter-gathers to being moon-walkers during one of the most stable and benign periods in all of Earth's history.

"Once a threshold-induced planetary state shift occurs, there's no going back. So, if a system switches to a new state because you've added lots of energy, even if you take out the new e
