The wonders of Water:
We survive because of water – no surprises there – and we all know of lots of ways in which water is essential for life but did you know ……
….. that water is responsible for warming the planet?
Without water vapour in the atmosphere (where it makes up only a maximum of 4% of the atmosphere) , the earth would have an average temperature of – 20 oC, instead of +15 oC as water is the most important greenhouse gas. This would mean no liquid water and no life – pretty amazing, eh? 😎
