The water cycle sounds simple.
voice-verified
It's the process by water evaporates from the earth and then comes down again as rain.
voice-verified
But what this report says is that it's become increasingly erratic, and that's because what can change is where the water comes from and how it falls.
voice-verified
What happens is because we've got increasingly high temperatures because of climate change, fresh water is vanishing up into the sky from lakes and rivers
voice-verified
Many a people of course depend on lakes and rivers for fresh water, both for drinking and for crops, and those levels in lakes and rivers the report shows have fallen.
voice-verified
But then there's the question of how and when the water falls.
voice-verified
What goes up of course must come down, and if there's more water in the sky in terms of clouds and humidity, more water will fall, and that can cause flooding.
voice-verified
And and I think this sometimes causes problems for people to understand.
voice-verified
How can climate change cause both drought and flooding?
voice-verified
Well that's because first of all the water may go up slowly and then all fall in one go.
voice-verified
Or of course there may be more water loss in hot places, more water loss through evaporation, which then falls in colder countries as flooding.
voice-verified
Glaciers, it explains, work as a buffer, and in fact, in a rather good graphic phrase, what it says is glaciates operate as the world's savings account in terms of water.
voice-verified
They freeze, obviously, when the weather's cold, more water freezes, and then when it's warmer in the summer, that water is released again.
voice-verified
The trouble is the glaciers are retreating, and it has a very good way of visualizing it.
voice-verified
What it says is that every year the Earth glaciers are losing water.
voice-verified
water equivalent to five hundred million half a billion Olympic swimming pools.
voice-verified
So what does that mean?
voice-verified
Well
voice-verified
First of all, that current account I was describing to you is depleted, we don't have it anymore.
voice-verified
Secondly, those glaciers may break up and melt with catastrophic consequences, which we of course saw last month in Nepal when what was probably the cause by a glacier melting and then breaking off caused the flash flooding which resulted in thousands of deaths, and also towns and villages completely destroyed.
