Hothouse Earth. A very unsafe operating space for human beings — indeed, totally uninhabitable. As Earth warms, at an increasing pace, invisible points of no return transgressed, that’s where we may be heading. The GPM speaks with the co-author of a recent report, and listens back to a conversation with a pioneer in Earth systems science, Will Steffen.

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.

Oceans of clean energy on humanity’s doorstep — wave, tidal, surface heat and, wherever freshwater flows into the sea … salt gradient energy. Tipping points in Earth systems. Unstable states world governments need to prepare for now. And, America’s Passionate Attachment to Israel. Loyalty is a must.

Planetary Boundaries Breached

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.”

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.

Cryosphere

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.
