Frozen viruses in Tibetan glacier unlock climate change secrets
Groundbreaking research on the Guliya Glacier in Tibet has discovered frozen viruses that could be the key to understanding climate changes on Earth. Scientists have studied thousands of years of climate history by analysing the genomes of viruses that survived in the ice. This discovery could help predict how future climate changes will impact our world.

Glaciers worldwide contain more than just ice – they are natural archives of our planet's past. Recent studies on the Tibetan Plateau have revealed an extraordinary discovery – frozen viruses from thousands of years ago that survived in the Guliya Glacier. These ancient microorganisms do not threaten humans, but their analysis can provide invaluable information about how the environment changes during extreme climate shifts.
Exciting discovery in tibet
Scientists made a groundbreaking discovery on the Tibetan Plateau, where they extracted ice samples containing frozen viruses from thousands of years ago. The research was conducted on the Guliya Glacier, located at an elevation of over 6,000 metres (20,000 feet) above sea level on the northwestern edge of Tibet. The extracted ice cores provided information on 1,705 species of viruses, most of which were entirely new to science. Interestingly, some of these viruses are about 12,000 years old and come from when Earth was transitioning from the cold last glacial period to the warmer Holocene.
This research provided fifty times more data on viruses originating from glaciers than previous analyses. This discovery is crucial for understanding how viruses adapted to past climate changes and what potential insights they can offer us about future climate shifts.
Can frozen viruses predict future climate changes?
The discovery of frozen viruses in Tibet opens new possibilities in climate change research. Although these viruses do not pose a threat to humans, their genomes contain key information on how viruses responded to changing environmental conditions in the past. Scientists collected data from three periods of climate warming over the last 41,000 years, allowing them to create an accurate picture of how viruses evolved and influenced their environment.
Researchers suggest that understanding these mechanisms could help predict how modern viruses will react to climate changes. Knowledge of how viruses adapted to extreme temperatures and conditions can assist in preparing for future challenges related to global warming. It is worth noting that this research could also impact space exploration, providing scientists with tools to identify microorganisms in extreme environments, such as ice on Mars or other planets.
This research shows that frozen viruses not only document the past but could also become crucial in predicting future changes in Earth's ecosystems.
