Greenland's ice cap usually melts in summer, but the season usually starts towards the end of May. This year it started at the beginning. According to Ruth Mottram, a climate scientist at the Danish Meteorological Institute, she has been "persistently" melting in the past four months. Greenland's ice sheet has lost 197 billion tons of ice this July alone – that's around 80 million Olympic swimming pools, according to Mottram. She told CNN that the expected average for this time of year would be between 60 and 70 billion tons.
The weather conditions that brought a heatwave to Europe last week have reached the Arctic, where scientists claim they could trigger one of Greenland's biggest ice melts since 1
Scientists registered unconfirmed temperatures of 2,7 ° C at 3,000 meters above sea level on Thursday, which would be close to a new record if confirmed.
 It came the same day as meteorologists reported that this July was as hot worldwide as every month in recorded history.
July global average temperatures are in line with preliminary data for July 1 to 29, published by the Copernicus Climate Change Program, which analyzes temperature data, and may be higher than the current record holder (July 2016) planet. The final data will be released on Monday.
Greenland's ice sheet is the second largest in the world The ice melt of the season has already contributed half a millimeter to the global sea level.
It comes in a summer when the Arctic has experienced "unprecedented" forest fires, which scientists say were fueled by high temperatures.
In June, the Copernicus Atmosphere Monitoring Service (CAMS) tracked more than 100 intense forest fires at the Arctic Circle.
Arctic temperatures are rising faster than the global average and providing the right conditions for forest fire propagation, Mark Parrington, a senior scientist at the European Center for Medium-Range Weather Forecasting (ECWMF), told CNN last week.
