Antarctica: Second record-breaking hot day in a week

Experts say melting ice on the coldest continent is accelerating the rise in sea levels worldwide.

A new record high temperature has been registered in Antarctica for the second time in a week.

Almost 21 degrees Celsius (70 degrees Fahrenheit) was recorded for the first time – that is hotter than Madrid in Spain or Dallas in Texas.
