A recent study indicates that dust plays a significant role in the Arctic's climate changes, affecting how clouds form and their impact on the region's climate dynamics.

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.
