The worst predicted impacts of climate change are starting to happen — and much faster than climate scientists expected

“Historians may look to 2015 as the year when shit really started hitting the fan. Some snapshots: In just the past few months, record-setting heat waves in Pakistan and India each killed more than 1,000 people. In Washington state’s Olympic National Park, the rainforest caught fire for the first time in living memory. London reached 98 degrees Fahrenheit during the hottest July day ever recorded in the U.K.; The Guardian briefly had to pause its live blog of the heat wave because its computer servers overheated. In California, suffering from its worst drought in a millennium, a 50-acre brush fire swelled seventyfold in a matter of hours, jumping across the I-15 freeway during rush-hour traffic. Then, a few days later, the region was pounded by intense, virtually unheard-of summer rains. Puerto Rico is under its strictest water rationing in history as a monster El Niño forms in the tropical Pacific Ocean, shifting weather patterns worldwide.”
On July 20th, James Hansen, the former NASA climatologist who brought climate change to the public’s attention in the summer of 1988, issued a bombshell: He and a team of climate scientists had identified a newly important feedback mechanism off the coast of Antarctica that suggests mean sea levels could rise 10 times faster than previously predicted: 10 feet by 2065. The authors included this chilling warning: If emissions aren’t cut:
“We conclude that multi-meter sea-level rise would become practically unavoidable. Social disruption and economic consequences of such large sea-level rise could be devastating. It is not difficult to imagine that conflicts arising from forced migrations and economic collapse might make the planet ungovernable, threatening the fabric of civilization.”

In an amazing one-two punch of scientific understanding, the University of Georgia and Arizona State University have, independently, brought new insights into the root causes of accelerated climatic disruption, unprecedented species extinctions, resource depletions—all at the hands of humanity—plus a dramatic spurt of population growth in the last couple of centuries and the resulting threat of human self-extinction.
“You can think of the Earth like a battery that has been charged very slowly over billions of years. The sun’s energy is stored in plants and fossil fuels, but humans are draining energy much faster than it can be replenished.”
In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technological-informational economy, to grow our population to more than 7 billion, and to transform the biogeochemical cycles and biodiversity of the earth.
This rapid discharge of the earth’s store of organic energy is what fuels the human domination of the biosphere, including conversion of natural habitats to agricultural fields and the resulting loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear, hydro, wind, and solar energy sources.
The laws of thermodynamics, part of physics, govern the trickle-charge and rapid discharge of the earth’s battery and are therefore universal and absolute. In the long span of universe history, Earth is only temporarily poised on its outpost, some distance away from the thermodynamic equilibrium of outer space.
With the rapid depletion of the chemical energy stored in planetary biomass, however, the earth is shifting back toward the inhospitable equilibrium of outer space—with fundamental ramifications for the biosphere and humanity. Because there is no substitute or replacement energy for living biomass, the remaining distance from equilibrium that will be required to support human life is unknown.
