ANCHORAGE (Reuters) - If carbon emissions continue at current rates, so much mercury will leach from thawing permafrost that fish in the Yukon River could become dangerous to eat within a few decades, according to a study published Wednesday in the journal Nature Communications.
Current emissions rates threaten to trigger enough thaw release to drive mercury levels in Yukon River fish above federal safety guidelines by 2050, according to the study.
