H.S.H. Prince Albert II and girlfriend Charlene Wittstock have wrapped up a visit to the United States. He visited Washington DC to tend to some government business, met with Secretary-General Ban Ki-Moon at the United Nations in New York on the 19th and yesterday attended the Princess Grace Awards, presenting the prizes to the winners and rubbing elbows with numerous celebrities. The Princess Grace Awards Gala was held at Cipriani 42nd Street. At the end of this week the Sovereign Prince will be in San Diego, California to speak at the Bright Green Future Conference where he will also be given the Scripps Institute of Oceanography’s Roger Revelle Prize on Friday. The award, and what the prince will most likely be speaking about, was given for the Prince's work in studying and raising awareness of the danger to marine life from rising levels of co2 in the oceans caused by global warming.
