Scientists capture dramatic footage of Arctic glaciers melting in hours
Scientists have captured dramatic footage of massive lakes in the Arctic melting away in a matter of hours.
Glaciologist Jason Box has been testing a Moulin, a shaft that allows water to travel from the glacier’s surface to its bottom, in a glacier on the Greenland ice cap to find out how fast it is melting.
Dr Box said: “The Moulin is the epicentre of our concern because all the water is running down at this one point.
“It’s just bottomless, no light escapes.”
Balanced on the edge of an ice sheet the team used a flow meter to measure the water speed.
He said: “There’s no escape from a Moulin. It’s just got danger written all over it. But the information is so important that we actually had to take that risk.”
The team found that in just one day 42 million litres fresh water drained down this one Moulin. Dr Box thinks there are hundreds, possibly thousands more Moulins across the Greenland ice cap.
Greenland is losing enough water each year to cover Germany a metre deep.
Dr Box, from Ohio State University, thinks the way to combat melting glaciers is to cover them with blankets that will reflect the sun’s rays.
Dr Box said: “We’re in the midst of a climate catastrophe and glaciers are the epicentre of that problem.
“Glaciers around the planted are decanting into the oceans at shocking rates and I want to stop that.”
SOME WORDS TO NOTE:
Epicenter; bottomless pit; flowmeter; flow rates.
1. How is climate affected by the melting of the ice in the North Pole?
2. Do you feel any of this climate changes here in Brazil? What/How?
