New research from Sweden's Chalmers University reveals unexpectedly high methane emissions from the Siljan Ring, Europe's largest meteorite crater. The study found that certain areas of Lake Siljan, which typically freeze over in winter, have open patches releasing methane at rates up to 300 times higher than usual. This localized emission is unusual and may indicate a unique source related to the meteorite impact. Researchers plan to investigate further, as these findings could have significant implications for understanding natural methane emissions globally. Teljes cikk (Euronews.com)
