Need to Know, May 20, 2011: Climate change and tropical disease, Upper Big Branch mine disaster, Stuxnet

This week, we explore the threats that climate change may already be posing to human health. We report on a rare but deadly fungal disease, previously known to occur only in tropical and subtropical regions, that has recently led to several deaths in the Pacific Northwest. Scientists believe climate change may have already affected the spread of other diseases like West Nile virus and dengue fever.

Also: We revisit the Upper Big Branch coal mining disaster, one year later, to find out the results of the investigation into the cause of the explosion. We also take a look at the sophisticated and alarming Stuxnet worm, the first major manifestation of a physical cyber attack that targeted an Iranian uranium enrichment facility last year.

And: We speak with John Esposito of Georgetown University on President Obama’s attempt to redefine the U.S.’s relationship with the Middle East in light of the Arab Spring, and Jon Meacham returns with another “In Perspective” essay.

     Given that it’s been verified that the Upper Big Branch mine blast was preventable it would be great if Don Blankenship were to be convicted of 29 counts of voluntary manslaughter and fined for the $12 million payout at least. Unfortunately, it appears the most he can be hit with would be a civil lawsuit. Unfortunately, the victim’s families won’t get justice for their losses.

    Great idea Chuck. Throw in some charges for having the security guards warn him mshaw was comin. Thats a federal crime.
