The Four Horsemen Of The Sixth Mass Extinction, Jeremy Hance

Periodically, in the vast spans of time that have proceeded us, our planet’s living beings have been purged by planetary catastrophes so extreme they make your typical Ice Age look like the geological equivalent of a stroll in the park. Scientists count just five mass extinctions in an unimaginably long expanse of 450 million years, but they warn we may well be entering a sixth.

Mourning The Changes That Surround Us: Readers Speak Out, By Dahr Jamail

In early July, I asked Truthout readers to share the weather anomalies they are witnessing on their home turf. Large numbers of readers responded with a range of harrowing observations, from vanishing snow, to shifts in seasons, to skyrocketing temperatures, to wildfires and floods. People often conceptualize climate disruption in very theoretical terms – as if it is a phenomenon that will take place in the future. However, as the Truthout community knows, the impacts of planetary warming are very real – and they are happening now.

So the advent of the Anthropocene shatters the self-contained world of social analysis that is the terrain of modern social science, and explains why those intellectuals who remain within it find it impossible to “analyze” the politics, sociology or philosophy of climate change in a way that is true to the science. They end up floundering in the old categories, unable to see that something epochal has occurred, a rupture on the scale of the Industrial Revolution or the emergence of civilization itself.

A stunning new study published in the prestigious journal Science concluded that we are on the verge of causing “a major extinction event” in the oceans, and one of the scientists who authored the study stated frankly, “I honestly feel there’s not much hope for normal ecosystems in the ocean” without a dramatic shift away from the current business-as-usual fossil-fueled economy. Additionally, another recent study found that sea levels are now rising 25 percent faster than previous estimates, and the acceleration witnessed in the 1990s is even more dramatic than previously calculated. To make matters worse, another major study published in Science recently found that human activity has already pushed the planet beyond four of its nine “planetary boundaries.” The conclusion of the study said that at the rate things are progressing, the coming decades will see the earth no longer as a “safe operating space” for human beings, let alone most other species. The four boundaries we’ve already crossed are the extinction rate, deforestation, atmospheric carbon dioxide levels, and the flow of nitrogen and phosphorous (land fertilizers) into the oceans.
