The largest ice island emerged because of climate change

Tens of billions of tons of ice on Greenland melt annually due to rising global temperatures. That phenomenon caused the rock beneath the ice to rise continuously.

Greenland, the largest ice island on the planet, is covered by a tape of several hundred meters thick. This ice formed after millennia. As the temperature on the earth's surface increases, the annual melting of ice on the island is growing.

The ice below the ice sinks deeper by the mass of ice. But when the ice melts, the mass of the ice decreases and the rock emerges.

Some US satellite navigation stations (GPS) are located on Greenland. They found that each year the rock beneath the ice rose about 15mm, Livescience reported.

Last year, the surge in temperature caused the rock to rise by 20mm in just 5 months - an amazing speed for the scientific community.

Michael Bevis, a researcher at Ohio University in the US, believes that the rock rises too fast because of the melting of the ice.

'I can't find any other explanation,' he said at the American Geophysical Association's annual conference in San Francisco yesterday.

The World Meteorological Organization once confirmed 2010 as the hottest year since the UN monitored its average annual temperature. The average temperature last year was 0.5 degrees C higher than the period 1961-1990.

Many data show that Greenland's southern half lost another 100 billion tons of ice in 2010. Because of the soft soil above the rock, Bevis and colleagues can calculate the volume of the ice based on the stratum of the floor. rock. This is like compressing a spring in a scale to measure the weight of the person standing above the scale.
