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. The GPM interviews Radhika Desai and Gianluca Grimalda.
A small Canadian lake records humanity’s impact on Planet Earth. On the floor of Canada’s House of Commons, an old Nazi veteran gets a standing ovation. And, when official enemies are to blame, Canada calls for justice. For a beloved ally, Canada calls for justice to be suspended.
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.
Uranium mining in Niger: a filthy, toxic business. Fifty years after the end of America’s war on Vietnam, traces of US chemical weapons linger. And, the Anthropocene. A geologist talks about humanity’s transformation of Planet Earth.
After years of study, a scientific panel proposes a formal definition of the Anthropocene, naming the spot where humanity’s fingerprints are best observed in the rock record. A Canadian geologist relishes the moment. And, a First Nations elder reflects on the lake of her dreams and memories.
Nothing woolly-headed or Utopian about it: A universal, guaranteed basic income. A hundred years later, memories of war that do not fade. And, one of humanity’s great revolutions – the 1950s Great Acceleration has transformed Earth’s surface completely, hurtling our planet into an uncertain future.
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.
The roots of the US anti-abortion movement — misogyny, racism and hatred of immigrants. On the edge of a big Canadian city, an oasis of calm where wildlife thrives. And, the latest report from the World Meteorological Organization; its lead author is scared.
Drug-resistant infections – the new pandemic? And, a tangled network of tiny tubes, pulsating beneath our feet. Fungal networks below ground sustain life above.
Earth’s oceans are warming at a remarkable rate. Over ninety percent of the atmospheric heat humans have generated in the course of the past decades has been absorbed by Earth’s oceans. The consequences for oceans and atmosphere have been dire, and promise to play out over centuries, regardless of what we do.
Planet Earth is covered in water. Ninety-seven percent is in earth’s oceans. Most of the rest is frozen solid — locked up in sea ice and terrestrial ice sheets, glaciers and permafrost. Earth’s cryosphere plays a huge role in regulating climate. As our planet warms, its cryosphere is slowly melting, triggering positive feedbacks that make earth scientists worry.
Long before the ‘intractable conflict’ between Israeli Jews and Palestinians gets resolved, climate change will have thrown everything up for grabs — literally. It already has.
Earth’ surface is one degree warmer today, on average, than it was at the start of the industrial revolution 200 years ago. One degree doesn’t seem like much. The Paris Agreement would limit global temperature rise to two degrees. Sound like a conservative precautionary measure? Perhaps it isn’t.
A mild mid-March in Canada’s notoriously frigid prairie capital cannot be definitively pinned on global climate change. Still, for anyone willing to listen, read and watch, the writing is on the wall. Earth is warming — and fast.
Things constantly change. Everyone knows it. Steady, sometimes sudden change provides contour to individual human lives. Now, it seems humans have changed planet Earth like it’s never been changed before.
It would be difficult to go a day without stainless steel, and that steel would not be stainless without ferrochrome — the end product of chromite mining. In northern Ontario, chromium mining generates controversy.
