How does Earth maintain a constant level of oxygen?



It doesn’t! The oxygen level of the planet has varied quite dramatically in the last 500 million years. It was 35 per cent during the Carboniferous period, around 300 million years ago; as the climate, cooled and land plants died off, oxygen fell to as low as 12 per cent by the beginning of the Triassic. Back then, the air at sea level would have felt thinner than at the top of the Alps today.


Burning fossil fuels has reduced oxygen levels very slightly – about 0.057 per cent over the last 30 years. Deforestation only has a small effect because when rainforest is cut down, other plants are usually grown in its place. But it’s marine phytoplankton (plant plankton), rather than trees, that produces about 75 per cent of atmospheric oxygen. Global warming will have a significant impact on phytoplankton, which is a much more serious threat to oxygen levels.

It echoes. 🌠 Episode 6 – The Anomaly Spreads The Cosmic Core of Lyris-9 pulsed once—then again. But this time the resonance did not remain on one planet. Across distant systems, deep beneath forgotten worlds, other Cosmic Cores began to respond. Their light awakened slowly and cautiously, like memories returning after centuries of silence. Andrew Elsan felt it instantly. He staggered backward, gripping his chest as waves of unfamiliar voices filled his mind. Not words. Presence. Fear. Hope. Longing. “They’re… answering,” Andrew whispered.  Beside him, Aera Valen closed her eyes. Her breathing aligned with the rhythm of the Core. “I can hear them,” she said softly. “Worlds made of water… dust… crystal. They’...

🏅 The Story Behind the Nobel Prize

🏅 The Story Behind the Nobel Prize How one inventor’s reflection created the world’s most prestigious award 📜 The Origin of the Nobel Prize The Nobel Prize traces its origins to Alfred Nobel , a Swedish chemist, engineer, and inventor best known for inventing dynamite. Despite his scientific brilliance, Nobel was troubled by the destructive uses of his inventions. In 1888, a French newspaper mistakenly published Alfred Nobel’s obituary while he was still alive. The headline reportedly described him as the “merchant of death.” Shocked by how history might remember him, Nobel decided to change his legacy. In his will, he dedicated the majority of his wealth to create prizes honoring those who bring the greatest benefit to humanity . Thus, the Nobel Prize was born. “The prizes shall be awarded to those who have conferred the greatest benefit to humankind.” – Alfred Nobel 🏆 Nobel Prize Categories Physics Chemistry Physiology or Medicine Literature Peac...
