Scientists from universities in Leeds, Edinburg and London have analysed satellite images of the Earth's globes, glaciers and mountains and found that around 28 trillion tonnes of ice have disappeared since 1994. The "staggering" loss is due to rising greenhouse gas emission and global heating.

"In the past researchers have studied individual areas – such as the Antarctic or Greenland – where ice is melting. But this is the first time anyone has looked at all the ice that is disappearing from the entire planet. What we have found has stunned us," so Professor Andy Shepherd, director of Leeds University’s Centre for Polar Observation and Modelling.

Their research further warns that sea levels could rise by a metre by the end of the century and the melting could reduce our planet's ability to reflect solar radiation back into space.

"To put that in context, every centimetre of sea level rise means about a million people will be displaced from their low-lying homelands," so Shepherd.
