He says he's in favor of researching geoengineering in order to gauge its effectiveness and its potential side effects...

Uruguay, of course, has other serious problems that will need to be addressed in order to maintain the welfare of its citizens.

One of the two pilots is believed to have been awake all night before the flight and the other was known to occasionally sleep in the crew lounge at Newark Liberty Airport. The FAA is expected to release new regulations on pilot work limits next year. "I don't think many regular company employees would be able to work 16 hours a day, five...
