U.S. top diplomat Rex Tillerson is facing questions about climate as he attends the Arctic Council summit which is underway in Fairbanks, Alaska.
The Arctic Council, which includes the United States, Russia, Canada and five other countries, meets every two years to tackle problems in the region, which is warming at a faster pace than any other part of the world.
Unlike former President Barack Obama, Trump has expressed doubts about whether human activity has a significant role in climate change, and is mulling whether to pull the United States out of a global pact to fight it.
