Earthquake, Tsunami, and Nuclear Power in Japan

August 17, 2011 by Karen Street

Grief was our first reaction when a civilized nation so prepared for earthquakes was devastated. Those of us who live in earthquake country found it hard to tamp down the fear that we can't protect ourselves from nature. Japan, so much better prepared than the West Coast, actually did quite well with the once-in-a-millennium earthquake (the previous largest in that area was M8.3, in 869 CE), but the tsunami killed thousands, left hundreds of thousands homeless, and may have a cost of hundreds of billions of dollars.[read more]

Image via Wikipedia In a Treehugger interview on Climate Change and Intergenerational Justice, NASA’s James Hansen says it is very unfortunate that “a number of nations have indicated that they’re going to phase out nuclear power… The truth is, what we should do is use the more advanced nuclear power. Even the old nuclear power is much...[read more]

Fukushima is Japanese For “It’s Much Worse Than You Thought”

June 24, 2011 by Lou Grinzo

I’m astonished that this interview ran on CNN. I had concluded that nothing short of a China Syndrome event could make the US media mention that still unfolding disaster again. Now that we have an admission from TEPCO that there was a complete meltdown of three cores, and we’re seeing radiation pop up in the US and other places around...[read more]
