Arctic Heating Four Times Faster Than Planet, Rivers Turn Orange

A new U.S. government report confirms the Arctic is warming nearly four times faster than the global average. This rapid heating is causing severe environmental changes. The National Oceanic and Atmospheric Administration (NOAA) issued its annual Arctic Report Card. It documents melting glaciers, shifting fish populations, and some rivers turning orange. The orange rivers are a newly documented phenomenon. Scientists say the color comes from metals, like iron, released from thawing permafrost—ground that was previously permanently frozen. This "greening" of the Arctic is a clear signal of widespread climate disruption. The changes threaten local ecosystems, food sources, and indigenous communities that rely on them.
