The Australian bushfire by numbers - they're horrifying.

• 1 billion animals burnt to death
• 3/4 of a million square miles of land burnt
• 8000+ buildings lost
• 29 people dead.

This is a summer we will never forget, and our scientists say it is just going to get worse.

Firefighters are true superheroes and a massive thanks to all those countries that came to our help.

Remember we are all in this together, and we all need to change.
