"Rusting Rivers" in Arctic An Ominous Sign Of Climate Change

Rusty water in a waterway in the Arctic. The permafrost
is melting, which releases metals that were once frozen
into place, onto the surface. 

High up in the Arctic, rivers and streams are turning red-orange, as if billions of nails were rusting away and flowing into what should be pristine brooks way up there. 

As NPR reports, these rusty rivers are now widely documented in the Brooks Range in northern Alaska. 

"Hundreds of Arctic rivers and streams are turning bright red-orange, not from chemical pollution, but from naturally occurring iron spilling from long-frozen ground as temperatures warm. 

The "rusting rivers" phenomenon, which has been documented across the Brooks Range in northern Alaska, offer a vivid example of the effects of climate change in a region that is warming faster than the global average."

Other metals, like aluminum and copper are also being release from the thawing permafrost, NPR says. Those metals can do a number on fish and other animals in the food chain. People are also wondering if the metals might contaminate rural drinking supplies, but so far, there's been no evidence of that. 

This information comes from an annual  "Arctic Report Card" that was recently released by the National Oceanic and Atmospheric Administration (NOAA). They've been doing this for 20 years because the Arctic is the fastest warming place on Earth. And what goes on in the Arctic doesn't stay in the Arctic. 

This annual report is threatened because - big eye roll - the Trump administration does not want any government reports to even hint at climate change. He's terribly allergic to the term, constantly referring to idea of a warming world as a "hoax"

Scientist hope to keep the report card going, maybe by working around the United States.  

As NPR reports:

"An independent network of global scientists writes and compiles the research in the annual report, offering it some shelter from political winds. Some sections of this year's edition openly discuss the effects of climate change, and at least one study notes its major cause - burning fossil fuels."

Let's hope Trump doesn't find out about that line.

It's depressing to realize that basic scientific facts are now much like Soviet-era samizdat, publications that take great risks at offending the Fascist In Chief. We can't be sure if there will be another valuable Arctic Report Card next year 

Other information in the 2025 Arctic Report Card:

-- The Greenland Ice Sheet lost 129 billion tons of ice in 2025, continuing its long term trend. 

-- Alaskan glaciers have lost an average of 125 vertical feet since the 1950s. 

-- Arctic sea ice reached its lowest level on record this fall and early winter. 

-- The period from October 2024 to September, 2025 was the Arctic's warmest and wettest on record. 

-- Because of the increased precipitation in the Arctic, snow cover was above average during the heart of winter.  But the snow cover was well below normal by June, because of the unusual Arctic warmth. 

-- The relative lack of ice and snow allows the sun to heat the ground and water in the Arctic more than it would otherwise. That makes existing left over snow and ice melt even faster. It's called a feedback loop.    

As I've said before, what goes on in the Arctic doesn't stay in the Arctic. As much as climate change is messing up the top of the world, its effects will bleed down to the mid-latitudes through higher sea levels on the coasts, and bigger, more destructive storms.
