  1. Crowded Planet: A Conversation with Alan Weisman

    Over the course of the past one hundred years, we humans have grown in population at a rate rarely seen outside of a petri dish. Alan Weisman, author of the best-selling The World Without Us, spent two years traveling to twenty nations to investigate what this population explosion means for our species as well as those we share the planet with—and, most importantly, what we can do about it. His book Countdown: Our Last, Best Hope for a Future on Earth? will be released later this month. Orion managing editor Andrew D. Blechman met with Alan at his home in rural Massachusetts, amid birdsong and the patter of rainfall, to discuss some of the most serious issues ever to face the human species.

    We know our sun is vast and blazing. But sometimes it’s blazing more aggressively than others. Positively storming. Last week, the largest solar storm in almost a decade boomed out with a wave of cosmic energy across the 93 million miles to Earth. And we got hit.

    Superheated gas hurling waves of particles off the sun. Slamming Earth’s magnetic field. Threatening power grids, orbiting satellites, GPS signals, airline flights, radio communications. And making some amazing Northern Lights.
