- 1Permafrost and wildfire emissions could amplify climate change by 30%●Permafrost, wetland, wildfire and freshwater emissions could amplify climate change by up to 30%, study finds
A new study finds that carbon emissions from permafrost thaw, wetlands, wildfires and freshwater systems could amplify climate change by as much as 30%, adding to warming already driven by human activity. The findings highlight natural feedback loops that are increasingly releasing greenhouse gases as the planet heats, suggesting climate projections may understate future warming.
- 2Arctic thaw is turning Alaska's rivers orange, study finds●As the Arctic warms and tundra thaws, minerals long trapped in frozen soil are leaching into rivers, turning them orange
Scientists in northern Alaska report that thawing permafrost is releasing minerals once locked in frozen soil into rivers, turning the water orange and acidic. The study found these 'rusting' waters are more metallic and more acidic than drainage from metal mines, raising concerns about impacts on aquatic ecosystems as the Arctic continues to warm.
- 3Arctic permafrost thawing and releasing heat-trapping gases▼Arctic permafrost is thawing and leaking heat-trapping gas into the atmosphere
Arctic permafrost is thawing and releasing heat-trapping greenhouse gases such as methane and carbon dioxide into the atmosphere, adding a new driver of global warming. Scientists warn the process could create a feedback loop: warming temperatures melt more permafrost, which releases more gas, which accelerates warming further.
- 4Alaska's rivers turning bright orange as permafrost thaws▼Alaska's rivers are turning bright orange - and we know why
Rivers across Alaska are turning a striking bright orange, and scientists say they now understand the cause. Thawing permafrost is releasing minerals such as iron into waterways, rusting streams across the state's remote wilderness. The discoloration is raising concern about impacts on fish and ecosystems.
- 5Alaska permafrost soil found warming fastest▼In Alaska, soil in permafrost regions is warming the fastest
New research reports that soil in Alaska's permafrost regions is warming faster than other areas, raising concerns about accelerating thaw. Scientists warn that rapid warming of frozen ground could release stored carbon and destabilize infrastructure across the Arctic. The findings add to evidence that Alaska is among the fastest-warming parts of the United States, drawing attention from climate researchers and policymakers.

Popular Science reports that remnants of ice from the last ice age still exist on Earth today, preserved in places such as deep permafrost and polar regions. The piece highlights how ancient ice can persist for tens of thousands of years, offering scientists a record of past climates. Readers are engaging with the surprising idea that the ice age never fully ended in every corner of the planet.
- 7A fifth of Swiss Alpine glacier ice lost in five years●🏔️ A fifth of Swiss Alpine ice has vanished in five years https://www. swissinfo.ch/eng/glaciers-perm afrost/a-fifth-of-
Switzerland has lost around a fifth of its Alpine glacier ice volume in just five years, according to reporting by Swissinfo on glacier and permafrost monitoring. The rapid melt is attributed to persistently warm summers and low snowfall, continuing a dramatic retreat of ice across the Alps. Observers are sharing the figures as a stark marker of accelerating climate change in mountain regions.
- 8Alaska soil temperatures rising rapidly at depth, research finds▼Recent research demonstrates that soil temperatures across Alaska are rising rapidly and at considerable depths, with th
New research shows that soil temperatures across Alaska are rising quickly and at considerable depths, with the fastest and most severe warming occurring in high-latitude continuous permafrost regions. The findings point to accelerating permafrost thaw, a process scientists warn can release stored carbon and destabilise northern infrastructure, making the study notable for climate science and Arctic communities alike.
- 9Melting Permafrost Sends Toxic Metals Into Rivers at 70 Times Normal Levels●As Permafrost Melts, Toxic Metals Are Poisoning Rivers With Levels 70 Times Higher Than Normal https://www. sciencealert
New reporting from ScienceAlert says thawing permafrost is releasing toxic metals into rivers, with contamination measured at up to 70 times higher than normal levels. Scientists link the spike to Arctic ground that frozen for millennia now defrosting as the climate warms, releasing naturally stored metals such as iron and other elements into waterways. The findings raise concerns for ecosystems and communities that depend on these rivers, and are drawing attention as another example of climate change feedback effects.
- 10Arctic permafrost is leaking heat-trapping gas as it thaws●Heat-trapping gas once frozen in Arctic ground is slowly leaking and warming the planet
Greenhouse gases long locked in frozen Arctic ground are escaping as permafrost thaws, adding to planetary warming. Reports describe the leak as slow but steady, raising concern among scientists that it could reinforce climate change. The story highlights growing alarm over feedback loops in polar regions, where once-stable frozen soil is now releasing carbon that had been stored for thousands of years.
