Findings from European scientists were published in a journal late last year.

A new study found that the drying Great Salt Lake in Utah is now a major source of the gas emissions that are causing the climate to warm.

With the future of fossil fuels in question, an Australian oil company is branding its new Arctic development as climate-friendly.

Rivers and streams in Alaska are changing color – from a clean, clear blue to a rusty orange – because of the toxic metals released by thawing permafrost, according to a new study.

Recent discoloration of 75 streams in Arctic Alaska reflects increased iron and trace metal loading following climate-driven permafrost thaw. These findings have considerable implications for drinking water supplies and subsistence fisheries.

The oranging of northern rivers seems to be related to recent permafrost thaw that has allowed streams to release previously captive iron, trace metals and acid.

The EPA plans to limit or eliminate a chemical commonly used in car tires, known as 6PPD, after it was found to be fatal to salmon in preliminary Alaska sampling, in response to a petition from Native Tribes and several states, but the rulemaking process is expected to take years.
