Earth's atmosphere is slowly leaking oxygen, and scientists aren't sure why
Don't panic, but researchers have discovered that oxygen is (very) slowly draining out of Earth's atmosphere, and right now, they're not sure why. By analysing air bubbles trapped inside ice cores from Greenland and Antarctica, a team from Princeton University has found oxygen levels have dropped by 0.7 percent in the last 800,000 years, and figuring out why could be crucial to predicting our planet's future.
