Prince William will headline a virtual event on climate change set for Oct. 10. The Duke of Cambridge will speak at a TED Talk that will also feature Marvel stars Mark Ruffalo, Chris Hemsworth and Don Cheadle, former Vice President Al Gore and singer Yemi Alade.

Finding Freedom author Omid Scobie revealed Prince William's participation in the major event on his Twitter account. The all-day affair will also feature scientists, farmers, government officials, entrepreneurs, climate change activists, urban planners, investors and artists. The purpose of the event is to find more ideas to help the world address this pressing issue. 

Prince William said in December 2019 that humans need to "lead, innovate and problem-solve" as the Earth has reached a tipping point. Faced with an impending catastrophe brought the by destruction of natural resources, the Duke of Cambridge launched the Earthshot Prize to reward those with the best solutions to tackle climate change. 

The duke's initiative hopes to find five people who can provide answers to problems that will address air pollution, water pollution, biodiversity, energy use and preservation of nature. Earthshot Prize was inspired by former U.S. President John F. Kennedy's Moonshot program in the 1960s. 

Prince William received much support from environmentalist Sir David Attenborough for this idea. The royal also sought advice from his father, Prince Charles, and grandfather, Prince Philip, who are both avid farmers. 

It won't be the first time Prince William speaks out on climate change. Nearly a year ago, the royal also brought attention to the melting Chiatibo Glacier during his visit to Pakistan with Kate Middleton, the Duchess of Cambridge. 

Prince William said that surrounding communities vulnerable to this particular shift have to be aware of what's happening around them. He was encouraged to see young local leaders involved and engaged in the conversations around climate change. 

The Duke of Cambridge said during his visit that the U.K. and Pakistan need to work together to prevent an "impending global catastrophe." Over 200 million people will be affected if the flooding in the Pakistani mountains continue

Meanwhile, TED Talk head Chris Anderson said that climate discussion is always a top priority for the TED community. This year's forum will unite "all levels of society" to target a decrease in greenhouse gas emissions by 50 percent in 2030 and zero emissions in 2050. The free digital event will be streamed on the official TED website, as well as on YouTube.
