It's science, but not as you know it. The Naked Scientists.

Hello, future predict earthquakes. Also how seahorses are riding up the Thames in

significant numbers again and a hard-hitting story now. Scientists have

discovered why those balls that go straight up in the air off the bat are so hard

to catch and we'll be catching up with those stories in just a moment.

Hello.

Thanks Chris and this week we're also looking at the science of the sun. We'll be turning

back time 150 years to the largest solar storm that's ever been recorded, which wiped out communications

on Earth and caused boats to get lost at sea because their compass needles were spinning around

all over the place.

Why did it happen?

And what's the chances that it'll happen again?

We'll also be looking into the contentious link between the sun's activity and climate change.

So is global warming all down to natural variation in the sun?

We'll be finding out.

Plus there's a breath of fresh air in this week's

question of the week. I tend to drive of all the windows closed and the recirculation

function engaged. If the car were a perfectly sealed container, how big would it have to be for me to survive in it for a day?

And you can find out how long that person has to live inside the car a little later in the show.

Hopefully it will be long little later in the show.

Hopefully it'll be long enough to hear the answer.

Chris.
