"As the Arctic warms, its mighty rivers are changing in ways that could have
vast consequences – not only for the Arctic region but for the world.
Rivers represent the land branch of the earth’s hydrological cycle. As rain and
snow fall, rivers transport freshwater runoff along with dissolved organic and
particulate materials, including carbon, to coastal areas. With the Arctic now
warming nearly four times faster than the rest of the world, the region is
seeing more precipitation and the permafrost is thawing, leading to stronger
river flows.
We’re climate scientists who study how warming is influencing the water cycle
and ecosystems. In a new study using historical data and sophisticated computer
models of Earth’s climate and hydrology, we explored how climate change is
altering Arctic rivers.
We found that thawing permafrost and intensifying storms will change how water
moves into and through Arctic rivers. These changes will affect coastal
regions, the Arctic Ocean and, potentially, the North Atlantic, as well as the
climate."
