Ancient RNA offers a snapshot of a mammoth's life 39,000 years ago
Some 39,000 years ago, a woolly mammoth died in present-day Siberia, destined to be blanketed by ice and permafrost that would end up preserving its body — even down to the hair and muscle.

Earth's Past Temperatures Cooler Than Thought Read Full Article #ClimateHistory #PaleoClimate #EarthScience
🌡️ New research published in Nature Communications on July 9, 2026, reveals Earth's past temperatures were cooler than previously thought, with warm periods likely around 10°C above pre-industrial levels, not the up to 30°C once estimated.
🌏 This indicates that natural feedback processes have long regulated Earth's climate, allowing life to evolve and flourish over the Phanerozoic period (540 million years ago to present).
💡 The findings suggest human-driven warming could push Earth into unprecedented temperature ranges, emphasizing the need for human intervention to maintain a habitable climate.
