The Point of No Return: The Nightmares Are Already Here

First, to set the tone, excerpts from an essay in Rolling Stone, published six months ago:

The Point of No Return: Climate Change Nightmares Are Already Here

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."

Hansen's new study also shows how complicated and unpredictable climate change can be. Even as global ocean temperatures rise to their highest levels in recorded history, some parts of the ocean, near where ice is melting exceptionally fast, are actually cooling, slowing ocean circulation currents and sending weather patterns into a frenzy. Sure enough, a persistently cold patch of ocean is starting to show up just south of Greenland, exactly where previous experimental predictions of a sudden surge of freshwater from melting ice expected it to be. Michael Mann, another prominent climate scientist, recently said of the unexpectedly sudden Atlantic slowdown, "This is yet another example of where observations suggest that climate model predictions may be too conservative when it comes to the pace at which certain aspects of climate change are proceeding."

James Hansen, the dean of climate scientists, retired from NASA in 2013 to become a climate activist. But for all the gloom of the report he just put his name to, Hansen is actually somewhat hopeful. That's because he knows that climate change has a straightforward solution: End fossil-fuel use as quickly as possible. If tomorrow, the leaders of the United States and China would agree to a sufficiently strong, coordinated carbon tax that's also applied to imports, the rest of the world would have no choice but to sign up. This idea has already been pitched to Congress several times, with tepid bipartisan support. Even though a carbon tax is probably a long shot, for Hansen, even the slim possibility that bold action like this might happen is enough for him to devote the rest of his life to working to achieve it. On a conference call with reporters in July, Hansen said a potential joint U.S.-China carbon tax is more important than whatever happens at the United Nations climate talks in Paris.

Unfortunately, even Hansen has a tragically blinkered perception of what's happening in the world. Here's a clue, Jimmy:
It ain't just climate change...

What humans & livestock have done so far:

99% of Rhinos gone since 1914.
97% of Tigers gone since 1914.
90% of Lions gone since 1993.
90% of Sea Turtles gone since 1980.
90% of Monarch Butterflies gone since 1995.
90% of Big Ocean Fish gone since 1950.
80% of Antarctic Krill gone since 1975.
80% of Western Gorillas gone since 1955.
60% of Forest Elephants gone since 1970.
50% of Great Barrier Reef gone since 1985.
40% of Giraffes gone since 2000.
30% of Marine Birds gone since 1995.
70% of Marine Birds gone since 1950.
28% of Land Animals gone since 1970.
28% of All Marine Animals gone since 1970.
97% – Humans & Livestock are 97% of land-air vertebrate biomass.

10,000 years ago we were 0.01% of land-air vertebrate biomass.
Humans and livestock have caused 80% of land-air vertebrate species extinctions and now occupy half the land on earth.

Next, my favourite graphic:



Now, the Great Acceleration:


A final editorial note: Hansen is every bit as colonized by techno-industrial values as the rest of them: Klein, McKibben, Brown, Lovins, Hawken, Suzuki, Al Gore... Specialist seems to suffer severe blind spots when crucial information originates outside their area of specialization.

OK, my question is, why use a column from August 5, 2015 OKIsItJustMe Feb 2016 #5
why, would the conclusion be any different? phantom power Feb 2016 #6

We can't talk about it for fears of dictatorship.

I mean, what the fuck else can one say? Let's dance. Dance all around the actual problem, but not really look or talk about it. After all, what the fuck can we do about it? Be a sex dictator?

I have to admit, I don't know what to do. I do know one thing, this all boils down to what each person is doing, times a billion or so.

If you like what you see, keep behaving the same way. That's about all I can say.

It's 5am and I now realize my 5am posts can be a bit weird.

And, if you’re going to use a column from August 5, 2015, why not include the date?

The column itself is not from a scientific journal; it’s from Rolling Stone. (Something which would be clearer, if an open URL were used, rather than a linked headline.)

I'm a fan of transparency…

I'm reading Gar Alperovitz’s America Beyond Capitalism - almost done. Many good ideas and information on things i knew nothing about. But i couldn't help but see that he essentially has a blindspot when it comes to environmental issues. He seems to take for granted that we will have insane population growth and while there is discussion of climate change in terms of water, drought and sea level rise there is nada about ecological collapse. It's really hard to have hope these days.


thanks, i guess, for posting
