Queen Elizabethaddressed the assembled delegates via a recorded message as part of the reception, noting that climate change was a “subject close to the heart of my dear, late husband,Prince Philip, the Duke of Edinburgh.”

Sharing a memory from the start of Philip’s half-a-century-long campaign to fight climate change, she urged, “If we fail to cope with this challenge, all the other problems will pale into insignificance.”

She continued, “It is a source of great pride to me that the leading role my husband played in encouraging people to protect our fragile planet lives on through the work of our eldest son, Charles, and his eldest son, William. I could not be more proud of them.”

“Of course, the benefits of such actions will not be there to enjoy for all of us here today: we none of us will live forever,” she also noted. “But we are doing this not for ourselves butfor our children and our children’s children, and those who will follow in their footsteps.”

The Queen plans to the National Service of Remembrance in a few weeks and will continue to undertake light duties from Windsor Castle.
