The USA has a sovereign interest in Antarctica and the Arctic Ocean.

It also has interests in icefields within the sovereign borders of the country itself.

"The Impact of Global Warming on Glacier Mass Balance in the North Cascades, Washington (State, USA) and the Juneau Icefields, Alaska, USA., by Mauri S. Pelto and Maynard M. Miller, Foundation of Glacier and Environmental Research; World Resource Review, Vol. 13, No. 1, pp. 91-105. 2001.

...Conclusion
Glaciers in both the North Cascades of Washington and southeast Alaska have had similar mass balance histories. In particular substantial negative mass balances from 1976-1998. The negative mass balances have led to retreat of all 47 alpine glaciers observed in the North Cascades and the total loss of three glaciers. The negative mass balances are not limited to this region as indicated by the nearly ubiquitous retreat of small alpine glaciers in many ranges around the world.

The USA has made investment and has responsibilities.

Maynard M. Miller was a professor at the University of Idaho and was the founder of the Foundation of Glacier and Environmental Research. He brought young scientists from all over the world to Juneau every year, even into his retirement years. He was still leading expeditions to the glaciers within these icefields at the age of 81 years old in 2004. At that point he was contemplating retirement and handing over the leadership to the younger scientists involved.
