Global ocean surface waters have become 30% more acidic since the start of the Industrial Revolution
Proportionally, the Earth’s atmosphere is no thicker than the skin of an apple.
Nitrogen (78%) and oxygen (21%) which comprise over 99% of the dry atmosphere, are not greenhouse gases and do not contribute to the Earth’s greenhouse effect.
With no greenhouse effect to moderate its climate, the average minimum temperature on Mercury, the planet closest to the Sun, is -280 deg Fahrenheit.
Without a greenhouse effect, the average temperature on Earth would be 0 deg Fahrenheit.
Once emitted, carbon dioxide (CO2) can remain in the atmosphere for over 100 years.
