|PIC1|Following a private church service on Sunday in Pennsylvania, Prince Charles and wife Camilla continued their US whirlwind trip as they departed for New York.

Once in New York, Prince Charles and Camilla planned to visit Harlem Children's Zone, which runs the Promise Academy charter school and a range of social service, health and educational programmes.

The prince and duchess are to meet with schoolchildren and their families and observe a math carnival, basketball practice and rehearsal for Shakespeare's "A Midsummer Night's Dream."

On Sunday evening, Prince Charles received an award from Harvard Medical School's Centre for Health and the Global Environment. He gave a speech on environmental issues and received the award from last year's recipient, former Vice President Al Gore.

The Prince previously described climate change as the "biggest threat to mankind" and warned that we must act now before it is too late.

As an avid environmentalist, has called for greater determination
and political will from governments across the world to fight global warming.

"Climate change is now a critical issue for every Commonwealth country," he wrote in CPQ, the quarterly magazine of the Commonwealth Press Union (CPU).

"The challenge is to find ways to mobilise the whole of their society in tackling this ultimate threat to mankind."
