And what's the World Cup's climate impact?"}] 44:T510,

Scorching temperatures are expected at this year’s World Cup in the USA, Mexico, and Canada. How will players and fans cope? And how will it affect the action on the pitch?

Scientists are concerned about the impact of extreme heat on the biggest sporting event in history.

The organisers, FIFA, is introducing mandatory water breaks to keep players cool, but experts say the hot conditions may slow down the game and give an advantage to teams that play more matches in air-conditioned stadiums.

There’s also concern about the health effects on fans. FIFA has put in place measures such as cooling areas and misting systems, but some say the plans don’t go far enough.

The Climate Question hosts Graihagh Jackson and Jordan Dunbar chat to Dr Madeleine Orr, Associate Professor of Sports Ecology at the University of Toronto, and BBC Sport Correspondent Katie Gornall.

Katie also breaks down the carbon footprint of a World Cup that’s been described as one of the most polluting events ever.
