Trump has threatened several times to withdraw from the Paris accord saying it is crippling U.S. business.
Just days before, the President European addressed 55 world leaders from Arab and other Muslim-majority nations in Riyadh, Saudi Arabia. He has called for the agreement to be renegotiated.
Earlier this year, Trump declared that the USA would no longer be a part of the landmark 2015 accord with 196 countries, claiming the non-binding agreement imposed unfair standards on American businesses and workers.
Obama said he has become "obsessed" with the way news is handled and consumed, particularly by the young.
Obama was in China and India before he arrived in France.
