This vital study aims to refine climate models and enhance our understanding of ecosystem responses to global warming.
Renowned Virus Researcher Warns of Potential Pandemic Threat from Ancient Viruses in Arctic Permafrost
Renowned virus researcher Jean-Michel Claverie warns of the potential threat of future pandemics originating from ancient viruses emerging from Arctic permafrost. His groundbreaking discovery of ‘zombie viruses’ dating back up to 48,500 years highlights the urgent need for proactive research and risk mitigation strategies to address this public health concern.
Arctic Permafrost Thaw Accelerating Greenhouse Gas Emissions
Arctic permafrost region is now emitting more carbon dioxide and methane than it absorbs, contributing to accelerated global warming. Recent research indicates that the ongoing thaw is likely to persist, worsening the effects of climate change.
Scientists Warn of Potential New Pandemic Threat from Ancient Arctic Viruses
A team of scientists has issued a warning about a potential new pandemic threat that could be unleashed by ancient viruses frozen in the Arctic permafrost. The Earth’s warming climate could release these long-dormant viruses, leading to a major disease…
Study Reveals Impact of Permafrost Thaw on High-Latitude Food Webs and Carbon Fluxes
Alaska is facing the brunt of climate change, with rapid warming leading to the thawing of permafrost in the state’s interior. This thaw not only releases stored carbon into the atmosphere, exacerbating rising temperatures but also triggers decomposition, potentially impacting…
