In November 2010, DiCaprio donated $1 million to the Wildlife Conservation Society at Russia's Tiger Summit. DiCaprio's persistence in reaching the event after encountering two plane delays caused then Prime Minister Vladimir Putin to describe him as a "muzhik" or "real man". In 2011, DiCaprio joined the Animal Legal Defense Fund's campaign to free Tony, a tiger who had spent the last decade at the Tiger Truck Stop in Grosse Tête, Louisiana. A benefit "11th Hour" fine art auction he organized in 2013, raised nearly $40 million for his foundation. He told attendees, "Bid as if the fate of the planet depended on us." It became the world's highest-grossing environmental charity event ever held. In 2014, he was appointed as a United Nations representative on climate change, and later that year he made an opening statement to members of the UN Climate Summit. In 2015, he announced his intention to divest from fossil fuels. He again spoke at the UN in April 2016 prior to the signing of the Paris Climate Change Agreement.
