Most of us in the developed world read this week that more of the Arctic sea ice has melted away than ever in human history. I usually shy away from saying “I told you so”, but forecasting is one of my roles for clients and flooding of our major cities is about to affect billions of lives – so a plug for my perspicacity is appropriate. Thus, what terrible doomsday does the melting ice portend?
The oceans have a surface area of 335 million square kilometres. Antarctica has an area of 13.8 million square kilometres which is 98% covered in ice, with a depth of up to 5 kilometres. Greenland, in the Arctic, has an area of 2.2 million square kilometres, with an ice cap of up to 2.6 kilometres. Should both the Antarctic and Arctic land based ice caps melt, the sea-level would rise 113 metres, or 370 feet. Eighty percent of all the people in the world live below 300 feet, on the coastal margins. Greater London is all below 300 feet. Florida’s east coast urban areas are below 30 feet. Manhattan Island rises just 36 feet above the ocean. The infamous settlement of Monmouth Junction in New Jersey is built at 135 feet above sea-level. The centre of Oxford, England is 200 feet above sea-level. SW2000 Telework Studies 1994.
The above passage from Out of the Depths is accurate. When the land based ice sitting atop Greenland melts – and the ice on Antarctica melts – the sea level will rise by 300 feet – or 100 metres. This is the Biblical Flood of Noah on a grand scale. WHEN the rising waters will come to a town or coast near you depends on how rapidly ice melts. Try this experiment: put an ice cube on your desk and take bets on how long it will last. For a seemingly long time it just sits there defying the warm air; it seems it will never melt; then suddenly it collapses and within minutes runs to water.
