A group of scientists measured the melting rate of some snowy rivers in Alaska using sonar technology.
Where the results showed melting glaciers 100 times faster than before.
The team measured the solubility rate in two periods, taking into account the temperature of the groundwater, salinity and velocity of the glacier.
Rising sea levels due to the melting of glaciers threaten the existence of some low-lying cities such as Shanghai and London, some of Florida's lowlands, or may lead to the survey of countries such as the Maldives.
