- 1Ancient Warming Episode Saw Temperatures Soar 45 Degrees▼About 304 million years ago, Earth’s average surface temperature climbed by 45.5 degrees Fahrenheit while carbon dioxide
About 304 million years ago, Earth's average surface temperature climbed by 45.5 degrees Fahrenheit while carbon dioxide levels doubled. Research published in August 2026 traces this prehistoric warming to a combination of volcanic activity, shifts in Earth's orbit, and thawing permafrost. Scientists say the episode offers a rare deep-time analogue for how greenhouse gases and feedback loops can drive dramatic climate change, drawing attention as modern CO2 levels continue to rise.
