The Great Acceleration: Earth systems commandeered by permanent human growth economics, fueled by coal, oil and gas. A quarter of the planet’s core energy base — natural primary productivity — appropriated for human food, fiber and fuel production. The GPM speaks about human socioeconomic metabolism and appropriation of net primary production with Vienna University ecologist Fridolin Krausmann. And, about the mid-20th century Great Acceleration with Georgetown University historian John McNeill.

Living on the edge of inferno. Perfectly normal for the people of Iceland, where volcanoes and ground cracks spew red hot magma. The GPM speaks with an Icelandic Earth scientist. Magma and the rock it turns into can be put to work, pumping carbonated water into it, turning atmospheric CO2 into limestone, for good. We speak about this with a Columbia University geologist.

The geology of cities — built out of stuff mined from the ground. That’s where all cities will end up, broken down and fossilized. The GPM speaks with a geologist who gazes into the future. Some human-made molecules won’t break down either. Forever chemicals, they’re called, and they’re everywhere. In non-stick cookware, cosmetics and clothing. They last forever, and they’re toxic. On a happier note — the human microbiome. All those bacteria living on us and in us, delivering crucial services. Nothing more amazing than the bacteria in the gut of a pregnant woman, steering healthy fetal development.

Risky moves: A Canadian political scientist attends a sanctioned forum in Russia — and asks Vladimir Putin a question. An Italian climate researcher refuses to return to work fast, from the other side of the planet. Slow travel releases less carbon, he tells his bosses.

Six out of nine planetary systems key to the survival of the human species are under threat. Is Earth still a safe operating space for human beings? And, a mega-engineering project to save an endangered African lake — on the drawing board, and very worrisome.
Six out of nine planetary systems key to the survival of the human species have been compromised, breaching the estimated boundaries of Earth system stability and resilience and pushing it “well outside of the safe operating space for humanity.” The GPM spoke with Katherine Richardson, lead author of “Earth beyond six of nine planetary boundaries.”
The Anthropocene defined — geologically. I speak with Jan Zalasiewicz about the history and work of the Anthropocene Working Group. Zalasiewicz was its first chair.

Humanity’s impact on Planet Earth has a name: the Anthropocene. The start of Earth’s human age can be pinpointed in ice and biological cores, and the bottom sediments of bays and lakes — including a small lake in southern Ontario. But human beings have no control. And now we stand at catastrophe’s door.

A US Supreme Court ruling throws American wetlands under the bus. In the oven, wheat and corn flour turn into bread and tortillas; spread on farm fields, rock flour reacts with carbon dioxide, turning into carbonates that get stored – forever. And, sharp questions off his tongue and a smartphone in hand, a Canadian activist ambushes politicians.
