Question: How long do you predict we have before we have major floods due to the ice melting?

If all the ice (all the glaciers, ice sheets, icebergs) in the world melted, we would expect the sea level to rise by about 50 metres (that’s a lot!) – which would be very bad – but we do not expect climate change to melt all the ice.

As the climate warms though, the water in the oceans takes up slightly more space, (because it becomes less dense). This process actually increases sea-levels more then the melting of ice, so this is something scientists are working on to try and understand better.
