Hello, you're about to listen to a BBC podcast, so I'd like to tell you where you'll find more just like it.

Whether that's developing fresh formats or facilitating eye-catching artwork, I helped project manage all the details that make our podcast stand out.

At the BBC, we've got access to storytellers

And proving that scientists are never really off duty, it was at that very moment that climate scientist Peter Stott had the spark of an idea.

He realised that using complex climate models developed by his

team at the UK's Met Office Hadley Centre, he might be able to study a single extreme weather

event, such as this very heat wave mathematically, and figure out the extent to which human influences

were increasing the probability of these events. That's exactly what he went on to do,
