Three Climatic Monsters with Asteroid Impact

Three monster climatic events are currently shaping up to collide. It’ll be like an asteroid collision. In that regard, this article, in two parts, explores real, already happening, indisputable climate change that is starting to take down ecosystems throughout the biosphere. It’s happening now.

For perspective on asteroids, the last one, 7 ½ miles wide, hit 65 million years ago (dinosaurs wiped-out), vaporizing sulfate rocks, filling the atmosphere with sulfuric particles, blocking out sunlight, temps dropped 18-29F, followed thereafter by vaporized carbonate rocks, emitting CO2 at the rate of 0.2 ppm over 100,000 years as temps increased by 5C.

Today, CO2 increases at the rate of 3.0 ppm after only 200+ years of anthropogenic (human) influence. Ergo, humans are 15xs more powerful than an asteroid! Try that one on for size mister extinction!

The three monsters are: (1) A State Shift in the biosphere; (2) Human-caused greenhouse gases –GHG- alter the planet, disrupting the Holocene Era of 10,000 years of Goldilocks’ climate, not too hot, not too cold, going away fast; (3) Collapsing ecosystems 100% due to human footprint, inclusive of excessive toxic chemicals galore, worldwide.

Monster #1, A State Shift has been detected in a landmark study by twenty-two biologists and ecologists (“Approaching A State Shift In Earth’s Biosphere,” Nature, June 2012), concluding that when more than 50% of ice-free land converts to crops, livestock, highways, schools, towns, bridges, cities or the human footprint in toto, the ecological web collapses. As of today, human impact is fast approaching that milestone, as the Great Acceleration smothers the planet with human footprint.

The crux of monster #1 involves inventory of ecologically productive land. How much and for whom? Estimates are 3-4 acres of ecologically productive land per capita for 7.5B people. The problem is: Twenty-five percent (25%) of the world’s population, i.e., the developed/industrialized countries, requires nearly 100% of ecologically productive land to support sustainability of lifestyles, like razor blades, automobiles, houses, and bread & butter and ice cream, beyond which natural capital goes into deficit.
