GR: Here’s an article that I hope at least my friends and family read. If it doesn’t worry and motivate you, then you are a victim of “willful blindness” a cognitive condition that can be either conscious or subconscious. You can recover from the subconscious condition, but it’s usually after you’ve fallen in a hole and wonder “why didn’t I see this coming.” However, you can make a conscious effort to reassess your beliefs and act to avoid the hole. And I assume that this is what’s going to happen as demonstrations like the massive climate march that just filled Pennsylvania Avenue continue to grow.

“While apocalyptic beliefs about the end of the world have, historically, been the subject of religious speculation, they are increasingly common among some of the leading scientists today. This is a worrisome fact, given that science is based not on faith and private revelation, but on observation and empirical evidence.
“Perhaps the most prominent figure with an anxious outlook on humanity’s future is Stephen Hawking. Last year, he wrote the following in a Guardian article:
Now, more than at any time in our history, our species needs to work together. We face awesome environmental challenges: climate change, food production, overpopulation, the decimation of other species, epidemic disease, acidification of the oceans. Together, they are a reminder that we are at the most dangerous moment in the development of humanity. We now have the technology to destroy the planet on which we live, but have not yet developed the ability to escape it.
“There is not a single point here that is inaccurate or hyperbolic. For example, consider that the hottest 17 years on record have all occurred since 2000, with a single exception (namely, 1998 [hottest on record to that point]), and with 2016 being the hottest ever. Although 2017 probably won’t break last year’s record, the UK’s Met Office projects that it “will still rank among the hottest years on record.” Studies also emphasize that there is a rapidly closing window for meaningful action on climate change. As the authors of one peer-reviewed paper put it [PDF paper published in Nature, Climate Change]:
The next few decades offer a brief window of opportunity to minimize large-scale and potentially catastrophic climate change that will extend longer than the entire history of human civilization thus far. Policy decisions made during this window are likely to result in changes to Earth’s climate system measured in millennia rather than human lifespans, with associated socioeconomic and ecological impacts that will exacerbate the risks and damages to society and ecosystems that are projected for the twenty-first century and propagate into the future for many thousands of years.
“Furthermore, studies suggest that civilization will have to produce more food in the next 50 years than in all of human history, which stretches back some 200,000 years into the Pleistocene epoch. This is partly due to the ongoing problem of overpopulation, where Pew projects approximately 9.3 billion people living on spaceship Earth by 2050. According to the 2016 Living Planet Report, humanity needs 1.6 Earths to sustain our current rate of (over)consumption — in other words, unless something significant changes with respect to anthropogenic resource depletion, nature will force life as we know it to end.
“Along these lines, scientists largely agree that human activity has pushed the biosphere into the sixth mass extinction event in the entire 4.5 billion year history of Earth. This appears to be the case even on the most optimistic assumptions about current rates of species extinctions, which may be occurring 10,000 times faster than the normal “background rate” of extinction. Other studies have found that, for example, the global population of wild vertebrates — that is, mammals, birds, reptiles, fish and amphibians — has declined by a staggering 58 percent between 1970 and 2012. The biosphere is wilting in real time, and our own foolish actions are to blame.” –Phil Torres (Continue: It’s the end of the world and we know it: Scientists in many disciplines see apocalypse, soon – Salon.com.)
