    When the Doomsday Clock was created in 1947, the greatest danger to humanity came from nuclear weapons, in particular from the prospect that the United States and the Soviet Union were headed for a nuclear arms race. The *Bulletin *considered possible catastrophic disruptions from climate change in its hand-setting deliberations for the first time in 2007.












  • Niobium and hafnium do not occur as free elements in nature, but are refined from mineral ores. They are used in semiconductors and superalloys.

    In addition to these two unusual elements, a significant number of particles contained copper, lithium and aluminum at concentrations far exceeding the abundance found in meteorics, or ‘space dust.’ “The combination of aluminum and copper, plus niobium and hafnium, which are used in heat-resistant, high-performance alloys, pointed us to the aerospace industry,’’ Murphy said.

    they are finding elements that don’t even occur in nature, and elements that do occur but in proportions in the atmosphere that have grown significantly since we started burning up rockets.

    Armchair scientists don’t seem to give actual scientists much credit.
