Lake Baikal shows signs of recovery from pollution and climate change.

What it means

Lake Baikal, the world's largest freshwater lake by volume, is showing signs of ecological recovery after decades of pollution and climate change impacts. The recovery is attributed in part to increased water flow from the Selenga River, which has risen to 145% above its long-term average since 2017, helping to flush pollutants and improve water quality. This suggests that natural hydrological changes are contributing to improved conditions in the lake.

Accuracy & sourcesGrounded

The claim is reported by Phys.org, a reputable secondary source, and is attributed to a named primary source (likely a scientific study or monitoring data). The reporting appears to be a direct summary of that source, so the claim is plausible and consistent with the source, though the primary source itself is not provided in the highlight.

How new
