From Paris, to Geneva and to London - this week we've seen record temperatures across Europe.
The hot weather has come with plenty of warnings from doctors.
And on Friday (July 26) came another one - from the United Nations.
It said the hot air is heading towards Greenland and could cause record melting of the world's second largest ice sheet.
(SOUNDBITE) (English) WORLD METEOROLOGICAL ORGANIZATION SPOKESWOMAN, CLARE NULLIS, SAYING: "In July alone, it lost 160 billion tonnes of ice through surface melting.
That's roughly the equivalent of 64 million Olympic-sized swimming pools." The Greenland Ice Sheet covers 80% of the island.
If all of it melted, it would raise sea levels by seven meters.
The rapid melting seen this year is causing grave concern.
And scientists say while some may have enjoyed this week's hot weather - we are also responsible for the serious side effects.
(SOUNDBITE) (English) WORLD METEOROLOGICAL ORGANIZATION SPOKESWOMAN, CLARE NULLIS, SAYING: "Such intense and widespread heatwaves carry the signature of man-made climate change.
Normally when you get a temperature record broken it's by a fraction of a degree.
What we saw yesterday was records being broken by 2, 3, 4 degrees.
It was absolutely incredible." The message is clear - extreme weather is here to stay, but the consequences are likely to be much greater still.
