Siberia's growing methane threat could offset 20% of global methane reduction targets by 2050

The #Arctic is warming at an accelerating pace. As #permafrost thaws across vast areas and wildfires become more frequent, large amounts of #methane (CH4) are being released. Together, these changes are reshaping the region's #GreenhouseGas emissions and further intensifying climate change.

In a study published in Science on August 6, an international team led by Professor Liu Yi from the Institute of Atmospheric Physics #IAP of the Chinese Academy of Sciences investigated how #CH4 #emissions in #Siberia are evolving under #ClimateChange. The study showed how atmospheric circulation promotes #wildfire activity and #methanogenesis and thereby drives the recent sharp rise in CH4 emissions.

Advanced genetic techniques and #microscopy offer new insights into anaerobic ciliate and methanogen #symbiosis https://phys.org/news/2024-10-advanced-genetic-techniques-microscopy-insights.html

Methanogenic #symbionts of anaerobic #ciliates are host and habitat specific https://academic.oup.com/ismej/article/18/1/wrae164/7737421 #ISEPpapers by @joro

"This study provides a clearer understanding of how anaerobic ciliates have evolved a mix transmission mode to both maintain and replace their symbionts over time"

"Global warming has occurred numerous times over Earth's history, with one such event happening 304 million years ago during the #LatePaleozoicIceAge. Studies have discovered increased sea surface temperature, ice decline and oceanic environments flooding the land at the time."
