Near-Term Human Extincton: Making the Case




RADIO ECOSHOCK show

Summary: SUMMARY: Retired ecology Professor Guy McPherson says extreme climate change will wipe out humans before 2050. Psychologist Carolyn Baker says grieve now for lost future. Environmental Horticulturist Kim Eierman on eco-beneficial home planting. Radio Ecoshock 140910 LISTENER WARNING: If you are feeling depressed or even considering suicide, this is not the program for you. People suffering from PTSD may want to think twice. The subject matter is very depressing. However, in next week's show I will attempt to counter the argument made by our guests, with at least some bleak optimism, and why we may not be doomed.

GUY MCPHERSON ON OUR EXTINCTION Let me ask you: Do you have days when you feel we are doomed as a species? That's every day, for our next guest. When a successful Professor of Natural Resources, Ecology, and Evolutionary Biology left the University of Arizona, for his mud hut retreat, he probably didn't intend to stir up the world. But that's just what Guy McPherson has done. He's becoming a voice for the worst fears of many people. In fact, McPherson says climate change has gone so far, so fast, humans will become extinct before 2050. Dr. McPherson makes his case, and offers ways to cope with the ultimate bad news, in a new book co-authored with psychologist Carolyn Baker. It's called "Extinction Dialogs: Living with Death in Mind". That's coming out this Fall. Eventual human extinction may not be as impossible as it sounds. In addition to James Lovelock, two of the world's top scientists, Professor John Schullnhuber in Germany, and Dr. James Hansen, formerly of NASA, have worried we'll blow past any survivable limits to climate change. In a speech to the "4 Degrees of More" conference in Australia, Schullnhuber suggested that if we reach 4 degrees, the whole thing could easily slide to 8 degrees, which most of us would agree is beyond human tolerance. Hansen wondered if we might blow off the atmosphere altogether, as apparently happened on Mars. That possibility has since been discounted by other scientists. Most of the big name scientists, other than James Lovelock, hedge their warnings with the idea that we could still save ourselves IF we mount a huge campaign to switch energy to renewable sources, and stop our carbon-wasting ways. Guy says it's too late for all that. We have already committed the Earth to a severe shift in climate, beyond the survival limits of not just our civilization, but of our species. Let's find out why Guy McPherson thinks we are finished. I ask Guy what he means by extinction. Does he mean most humans die, but there would be a few left in caves or around the Arctic ocean, as Dr. James Lovelock once suggested? His exact reply was: "I'm a conservation biologist, and when I say extinct I mean every member of the species is gone." McPherson has woven the risk of nuclear power into his story of our end times. He's right to say that if the global electric grid goes down, for any reason, whether due to a massive collapse, or a solar flare or big nuclear war - then up to 400 nuclear reactors could melt down like Fukushima. However, we don't know for sure that even those events would bring all electricity down, all over the world. So we may add a lot of radiation, leading to millions or even a billion cases of cancer, but that's not enough to depopulate the world, much less cause our extinction. That's my opinion, and I'm dead-set against nuclear power. I think they should all be shut down as soon as possible. Guy says the oceans are dying. Anyone who lives near the ocean, as I did for 25 years, knows that isn't true - yet. A growing chorus of the best oceanographers do say ocean acidification from our carbon pollution can change the whole food chain
