London (CNN Business) US President Donald Trump and environmental activist Greta Thunberg are getting top billing at Davos this year as the conference for global elites turns its attention to the climate crisis and sustainability . Two hours later, Thunberg — Time Magazine's Person of the Year — will open a debate on how to avert a "climate apocalypse." Trump, who is aggressively rolling back environmental protections and pulling the United States out of the Paris climate agreement, may well be challenged over his view on climate change. About 3,000 of the people who flock to Davos are official conference participants. The official conference schedule is filled with dozens of speeches, debates, performances and events.
