In last week's Radio Ecoshock show, Dr. Guy McPherson explained his scientific reasons why he thinks humans will become extinct before the year 2040. He outlined a combined ecological collapse, already on-going in the extinction of other species, a dying ocean, the prospect of abandoned or failing nuclear plants, and the over-riding shift of Earth's climate.

McPherson is a Professer Emeritus in natural science from the University of Arizona. He has collected masses of scientific papers, news articles, and statements to show the worst of all worlds developing.

Our next guest says Guy McPherson is wrong. Scott K. Johnson describes himself as "a geoscience educator, hydrologist, and freelance science writer contributing at Ars Technica." His personal blog is at fractalplanet.wordpress.com. An article there has become a focal point for people questioning McPherson and the whole idea of near-term human extinction. It's title is "How Guy McPherson gets it wrong".
