The previous season marked the highest temperatures in the Arctic for the past 125 years. March, typically the month with the greatest sea ice extent, recorded the lowest levels in 47 years of satellite data. The North American tundra exhibited unprecedented greenness, showing more vegetation than ever before.
These findings, released on Tuesday in the National Oceanic and Atmospheric Administration’s annual Arctic Report Card, illustrate the swift and dramatic changes taking place in the region as global temperatures rise.
“The Arctic is warming at a pace that exceeds the global average, with the last decade being some of the hottest on record,” stated Steve Sarr, NOAA’s acting principal scientist and associate administrator for ocean and atmospheric research.
Due to this warming, “over 200 watersheds in the Alaskan Arctic are turning orange as permafrost thaws, ecosystems evolve, and elements like iron are released into rivers,” Thursday indicated. The research highlighted increased acidity and higher levels of toxic metals in these discolored streams.
This is just one of many consequences of climate change affecting the region detailed in the report. This marks the 20th year that NOAA has published the Arctic report card, which originally surfaced during President Donald Trump’s second term.
The Trump administration has worked to diminish or eliminate other climate change reports, including the National Climate Assessment and the extensive climate disaster database. President Trump has labeled climate change a “swindler” and is actively trying to reduce the Environmental Protection Agency’s power to regulate greenhouse gas emissions.
Matthew Druckenmiller, a writer of the report and researcher at the National Snow and Ice Data Center, affirmed during a Tuesday press conference that the team faced “no political interference concerning our findings.”
Independent scientists consulted by NBC News remarked that the report conveys a similarly urgent tone and message as in previous years, with a few minor distinctions.
“Frankly, we haven’t observed a significant shift in tone compared to prior Arctic report cards, which is encouraging,” commented Tom Di Liberto, a climate scientist and media director at Climate Central. “The implications of their conclusions remain consistent with earlier Arctic report cards. The Arctic acts as a warning sign.”
Di Liberto, who previously worked in NOAA’s communications office before his position was cut in March as part of staff reductions, noted that the previous year’s report emphasized reducing fossil fuel production, whereas this year’s report does not mention fossil fuels at all. Otherwise, he identified no major differences.
NOAA unveiled a report at the American Geophysical Union’s annual meeting in New Orleans, highlighting how climate change is disrupting ecosystems and threatening livelihoods in the Arctic. This event is one of the largest scientific gatherings of the year, attracting thousands of scientists.
Mark Alessi, a climate scientist and fellow at the Union of Concerned Scientists, remarked that the report card “effectively communicates the realities of what is occurring on the ground in the Arctic.”
“Anyone reading this will understand that we continue to raise the alarm,” he emphasized.
In strong language, the report’s authors point out that proposed budget cuts to scientific programs collecting data in the Arctic, including satellite programs monitoring sea ice, threaten to undermine the data collection essential for this report and related decision-making.
“Aging infrastructure, along with risks to funding and staffing, could further erode existing AONs.” [Arctic Observing Network] Gaps are forming that hinder long-term trend analysis and decision-making,” the report warned.
Specifically, the report highlights several satellites within the Defense Weather Satellite Program set to be decommissioned in 2026. The cessation of these satellites will restrict sea ice measurements. It also mentions that the tundra greenness dataset will remain unchanged due to NASA funding cuts, and other climate datasets may also be jeopardized by proposed federal budget cuts in fiscal year 2026.
The Arctic is warming two to four times quicker than the rest of the globe, a phenomenon known as Arctic amplification. This process alters ocean currents and the degree of sunlight absorbed by the Earth’s surface at the poles.
“This feedback loop leads to the loss of sea ice and land ice, increased absorption of sunlight, and consequently, more rapid warming,” explained Alessi.
Temperature records are categorized by the Arctic water year, with the latest data ranging from October 2024 to September 2025.
