RE:Earth's Earliest ClimateLast paragraph…
“From its origin, life has greatly impacted its climate-atmosphere system — without permanently tipping the balance toward uninhabitability. However we also see that when conditions reach a tipping point (e.g., The Great Oxidation Event), change can be extraordinarily rapid and (as yet) irreversible. As we continue to impact the ocean-atmosphere system, we must look to deep-time climate change — particularly these abrupt and seemingly permanent transitions — to more fully frame our forecasts and design our solutions’
Pretty fragile little oxygen bubble we live in. Guess we better learn to get along and look after it.
