Fears over a US withdrawal from the climate change pact known as the Paris Agreement are starting to thaw.
It comes as nations with an interest in the arctic renew calls for the world to address global warming.
But US secretary of state Rex Tillerson, the former head of oil major ExxonMobil, says Washington will not rush to make a decision on its policies.
Mr Tillerson spoke in Fairbanks, Alaska, at a meeting of the Arctic Council, an advisory group made up of the eight Arctic nations and indigenous groups.
The council adopted a nine-page Fairbanks Declaration 2017, which noted that the Arctic is warming at more than twice the rate of the global average.
The document noted the importance of reducing soot and methane emissions and said climate change is the most serious threat to Arctic biodiversity.
Mr Tillerson signed the document, but in opening remarks, he cautioned that the US is reviewing several important policies, including how the Trump administration will approach climate change.
Mr Tillerson said to other representatives on the council: “We are appreciative that each of you has an important point of view, and you should know that we are taking the time to understand your concerns.”
“We’re not going to rush to make a decision. We’re going to work to make the right decision for the United States.”
The Arctic Council, he said, will continue to be an important platform as the Trump administration deliberates.
The president has said little about Arctic policy, but has taken steps to put US Arctic Ocean waters back in play for petroleum drilling.
The Arctic Council’s goals are sustainable development and environmental protection of the Arctic. The council does not make policy or allocate resources, and its decisions must be unanimous.
The US, an Arctic country because of the state of Alaska, is joined on the council by Canada, Russia, Denmark, Finland, Iceland, Norway and Sweden.
Swedish foreign minister Margot Wallstrom said she walked away from a private conversation with Mr Tillerson hopeful of US intent in the region.
She said: “He said, well, you know, we ought to first establish our climate policy and then decide on the Paris Agreement and how it relates
“And I think that sounds reasonable to do so.”
The worst-case scenario feared by some would be that Mr Tillerson used this gathering to announce the US would withdraw from the Paris Agreement.
Ms Wallstrom added: “Then that did not happen, and I think that bodes well for the future.
“I believe that we will see a continued American engagement and commitment to the Arctic.”
