Tapping Earth’s largest source of clean energy — its oceans. Ocean waves, tides and heat. A massive resource. Then, there’s salt gradient energy. Wherever fresh river water flows into salty seas, electricity can be generated, with zero carbon emissions.

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.

Sleeping and dreaming — essential and mysterious. An old Tanzanian friend speaks about torrential rains and village celebrations. And, in the Dutch city of Delft, a big university digs deep for the heat beneath: geothermal energy.
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.

Turning tall cane stalks into small, supple reeds for woodwind instruments. Decarbonizing construction; tons of carbon are embodied in buildings; there’s plenty of ways to decarbonize them. And, the Palestinian village of Jubbet al-Dibh. Last week, the Israeli military bulldozed its elementary school!.
London’s largest ever public protests for climate and Earth justice have come to a close. An estimated hundred thousand attended the four-day event, organized by Extinction Rebellion and other UK groups, rallying around the theme, “Unite to Survive.”

Young Israelis who refuse to serve in the military. And, as climate catastrophe sweeps the planet, in the Swedish city, Goteborg, engineers and students are designing the sort of building where people can live – comfortably — without squandering Earth’s limited resources, or polluting its atmosphere
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.
It’s the ultimate green dream: some device or substance that can capture the sun’s infinite flood of energy, store that energy, release it as heat and electricity — in controlled fashion — then absorb it all over again in a continuous closed loop. A little organic molecule called norbornadiene promises to make dreams come true, in the crucial realm of home heating and cooling.
Imagine an electric-powered fleet of Canada Post vehicles, along with vehicle charging stations at post offices. And postal banking, where loans could be secured for renewable energy installations and home energy retro-fits. Listen up.
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.
Will global capitalism eventually wean itself off fossil fuels? Can wind, solar, geothermal and other renewable energy sources generate enough joules to drive permanent economic growth? Should carbon emissions be taxed?
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.
Like Earth’s climate, Manitoba Hydro’s office tower — in the city of Winnipeg — is an integrated system. As Earth’s climate warms, energy efficient buildings like this will be in demand.

Stuart Franklin is turning air miles into trees. Franklin — the founder of a carbon offsetting project in Ecuador — calculates how many seedlings he needs to plant to capture the carbon dioxide emitted by tourists jetting to the Galapagos Islands each year.
