School strike for the climate

U.S. President Donald Trump on Jan. 21 assailed environmental "prophets of doom", delivering an uncompromising message in Davos after Swedish teenage campaigner Greta Thunberg slammed government inaction on the climate crisis.    

Swedish activist Greta Thunberg marched with 10,000 protesters in the Swiss city of Lausanne on Jan. 17 and said "you have not seen anything yet" before some head to Davos next week to challenge the global financial elite to fight climate change.
