Earth Pulses Every 5000 Years Scientists Discover Now
A study published in Nature Communications revealed that Earth experienced rapid climate fluctuations recurring every 4 to 5 thousand years 83 million years ago, pushing climate to oscillate between wetter and drier periods. The discovery adds a new dimension to understanding climate in warmer eras, as scientists previously knew major orbital changes affecting hundreds of thousands of years, but now shorter cycles between 1 to 6 thousand years have been detected. Researchers examined ancient Chinese rocks to uncover this pattern hidden from geologists for decades, linking these short cycles to direct astronomical influences on our planet. This means even ancient greenhouse worlds without ice were not stable as imagined, but experienced a hidden rhythm reshaping their climate with astonishing regularity.
