Climate Change

A groundbreaking study has achieved the seemingly impossible: scientists have successfully extracted and sequenced ancient RNA from the frozen remains of a woolly mammoth that roamed Siberia nearly 40,000 years ago. This incredible feat shatters previous beliefs about how long RNA, the fragile single-stranded molecule of life, can survive, offering an unprecedented window into the biology of extinct Ice Age animals.

Researchers at Tulane University have made important discoveries about how the amount of oxygen in the ocean has changed over thousands of years, and what this means for our climate future. By analyzing ocean floor sediments from the Arabian Sea, the team can measure past oxygen levels and link these findings to carbon dioxide levels in the atmosphere.

In recent years, the Mediterranean has become a hotspot for extreme weather, with deadly floods, record-breaking storms, and rising temperatures altering the region’s landscape. While heavy rainfall has always been part of Mediterranean weather patterns, the intensity and frequency of these events are escalating due to climate change—turning natural disasters into regular occurrences.
