Antarctica: ...and still it melts

President Trump announced his decision June 1 to pull the United States out of the Paris Agreement on Climate, signed by 195 nations and formally joined by 147, including the US. The United States now joins Syria and Nicaragua as the only nations in the world not supporting the accord. Nicaragua, it should be noted, failed to join because the terms of the accord are not binding, and it was therefore considered too weak. Syria is consumed by internal war, and was iced from the negotiations by restrictions on its envoys traveling to the talks. The agreement, which seeks to limit global warming to 2°C above pre-industrial levels, came into force on Nov. 4, 2016, just days before Trump was elected. Each country sets its own commitments under the accord. The United States, second-largest emitter on the planet after China, had committed to reducing its carbon emissions by 26 to 28% below 2005 levels by 2025. It also commited up to $3 billion in aid for poorer countries to address climate change by 2020. (ENS, June 2; NYT, June 1; WP, May 31)

Ominously, Trump's announcement comes just as scienists report that s massive crack in an Antarctic ice shelf has grown by 11 miles in the past six days—with one of the world's biggest icebergs ever poised to break off. The crack in the Larsen C ice shelf is now about 120 miles long, and only eight miles remain until it cuts all the way across, producing an iceberg about the size of the state of Delaware.

Adrian Luckman of Project MIDAS, a British research project that is monitoring crack, said this week saw the largest jump since January. The breaking point, known as "calving," is now said to be "very close."  Once the iceberg breaks off, it "will fundamentally change the landscape of the Antarctic Peninsula."

Three years to prevent climate catastrophe

From The Independent, June 29:

The world has three years to start making significant reductions in greenhouse gas emissions or face the prospect of dangerous global warming, experts have warned in an article in the prestigious journal Nature.

Calling for world leaders to be guided by the scientific evidence rather than "hide their heads in the sand," they said "entire ecosystems" were already beginning to collapse, summer sea ice was disappearing in the Arctic and coral reefs were dying from the heat.

The world could emit enough carbon to bust the Paris Agreement target of between 1.5 to 2 degrees Celsius in anything from four to 26 years if current levels continue, the article said.

Global emissions had been rising rapidly but have plateaued in recent years. The experts, led by Christiana Figueres, who as Executive Secretary of the United Nations Framework Convention on Climate Change played a key role in the Paris Agreement, said they must start to fall rapidly from 2020 at the latest.

Note that James Hansen and others have already predicted that even with the 2 degrees Celsius lmit established by the Paris Accord that the US just abandoned, New York, London, Calcutta, Shanghai and many other cities will be flooded and basically uninhabitable within a century. If current carbon output levels continue, we'll reach 6 degrees within a century, which would likely mean human extinction. A rise of 11 degrees has been broached. (AFP, Nov. 30, 2015; Slate, July 20, 2015; CNN, May 22, 2015; WP. Nov. 28, 2011)

Disintegration of Antarctic ice shelf: it's on

Well, that crack in the Larsen C ice shelf has now cut all the way across, producing (as predicted) an iceberg about the size of the state of Delaware. The ice shelf is now 12% smaller. The new massive 'berg weighs a trillion tons and contains as much water as Lake Erie—the biggest iceberg ever recorded. The media are full of don't-worry-be-happy commentators who keep reminding us that the giant breakaway iceberg will have no impact on sea level because the ice shelf itself was already resting on the ocean. More sober voices point out that as the ice shelves deteriorate, the inland ice sheets will start sliding into the sea. If the entire West Antarctic Ice Sheet were to melt, it would raise sea levels by a devastating 15 feet. Of course this would "take centuries," so don't worry about it. Fuck posterity, right?

Era of 'Biological Annihilation' underway

From the New York Times, July 11:

From the common barn swallow to the exotic giraffe, thousands of animal species are in precipitous decline, a sign that an irreversible era of mass extinction is underway, new research finds.

The study, published Monday in the Proceedings of the National Academy of Sciences, calls the current decline in animal populations a "global epidemic" and part of the "ongoing sixth mass extinction" caused in large measure by human destruction of animal habitats. The previous five extinctions were caused by natural phenomena.

Gerardo Ceballos, a researcher at the Universidad Nacional Autónoma de México in Mexico City, acknowledged that the study is written in unusually alarming tones for an academic research paper. "It wouldn't be ethical right now not to speak in this strong language to call attention to the severity of the problem," he said.

Dr. Ceballos emphasized that he and his co-authors, Paul R. Ehrlich and Rodolfo Dirzo, both professors at Stanford University, are not alarmists, but are using scientific data to back up their assertions that significant population decline and possible mass extinction of species all over the world may be imminent, and that both have been underestimated by many other scientists.

So here we are reading in the MSM that the sixth mass extinction is imminent or underway—the first (obviously) that is anthropogenic. This raises the question of whether we humans really are rational, conscious beings or, ultimately, a blind force of nature, like the meteor that wiped out the dinosaurs at the end of the Cretaceous...

The industrial system that is driving this planetary collapse is the fruit of rationalism. Yet its continuance is so thoroughly irrational. It's such a paradox.
