To the public, collapse is a term applied to a heart attack victim on a street corner or a building stricken by an earthquake or bomb. To a glaciologist, it describes the transition to unavoidable loss of an ice sheet — a process that can take centuries to get into gear, and millenniums to complete.

Collapse in the imagination of most people sounds like a catastrophic event that is going to happen in the next few years. We are talking about a retreat that is unstoppable because we think we have enough evidence to say that these glaciers will keep retreating for decades and even centuries to come…. We’re talking about a slow degradation of ice in this part of Antarctica.
Linguists identify 15,000-year-old 'ultraconserved words' - The Washington Post - 0 views

You, hear me! Give this fire to that old man. Pull the black worm off the bark and give it to the mother. And no spitting in the ashes! It’s an odd little speech. But if you went back 15,000 years and spoke these words to hunter-gatherers in Asia in any one of hundreds of modern languages, there is a chance they would understand at least some of what you were saying.

That’s because all of the nouns, verbs, adjectives and adverbs in the four sentences are words that have descended largely unchanged from a language that died out as the glaciers retreated at the end of the last Ice Age. Those few words mean the same thing, and sound almost the same, as they did then.

A team of researchers has come up with a list of two dozen “ultraconserved words” that have survived 150 centuries. It includes some predictable entries: “mother,” “not,” “what,” “to hear” and “man.” It also contains surprises: “to flow,” “ashes” and “worm.”

Geology's Timekeepers Are Feuding - The Atlantic - 0 views
-
, in 2000, the Nobel Prize-winning chemist Paul Crutzen won permanent fame for stratigraphy. He proposed that humans had so throughly altered the fundamental processes of the planet—through agriculture, climate change, and nuclear testing, and other phenomena—that a new geological epoch had commenced: the Anthropocene, the age of humans.
-
Zalasiewicz should know. He is the chair of the Anthropocene working group, which the ICS established in 2009 to investigate whether the new epoch deserved a place in stratigraphic time.
-
In 2015, the group announced that the Anthropocene was a plausible new layer and that it should likely follow the Holocene. But the team has yet to propose a “golden spike” for the epoch: a boundary in the sedimentary rock record where the Anthropocene clearly begins.

Scientists Can No Longer Ignore Ancient Flooding Tales - The Atlantic - 0 views
-
It wasn’t long after Henry David Inglis arrived on the island of Jersey, just northwest of France, that he heard the old story. Locals eagerly told the 19th-century Scottish travel writer how, in a bygone age, their island had been much more substantial, and that folks used to walk to the French coast. The only hurdle to their journey was a river—one easily crossed using a short bridge.
-
there had been a flood. A big one. Between roughly 15,000 and 6,000 years ago, massive flooding caused by melting glaciers raised sea levels around Europe. That flooding is what eventually turned Jersey into an island.
-
Rather than being a ridiculous claim not worthy of examination, perhaps the old story was true—a whisper from ancestors who really did walk through now-vanished lands

To really grasp the present, we need to imagine the future – then look back from it to better see the now. The angry climate kids do this naturally. The rest of us need to read good science fiction. A great place to start is Kim Stanley Robinson.

read 11 of his books, culminating in his instant classic The Ministry for the Future, which imagines several decades of climate politics starting this decade.
-
The first lesson of his books is obvious: climate is the story.
