Sky News reported:

The longest day of the year is almost here, but there has been barely a hint of summer in the UK - while parts of Europe swelter in record-breaking heat. 

Greece recorded its earliest ever heatwave last week, as temperatures soared about 38C for more than three days running.

It's a huge contrast to the weather in the UK, which has been "disappointingly cool" so far this month, Sky News meteorologist Steff Gaulter says.

"It seems like we're one to three degrees below normal for this time of year," David Schultz, a professor of Synoptic Meteorology at The University of Manchester, told Sky News.

Disappointingly, the cool weather can't be blamed on climate change and carbon emissions since it's more likely due to areas of low pressure over the UK and winds from the Arctic.

Swedish Lutheran Minister Greta Thunderberg has been surprisingly quiet about this cooldown but did promise a sermon on the dangers of the global cooldown, something everyone was worried about just a few decades ago.
