Join Hugo, Richard and Geraint on a tropical island adventure where we discover the importance of ozone near the equator. We discuss how ozone is transported though the atmosphere and ask the question: "How do the towering storm clouds in the tropics affect the composition of the atmosphere?" We travelled halfway across the globe to Papua New Guinea with our weather balloons to gather the data that we needed to find out.

This was recorded in February 2014 during the Co-ordinated Airborne Studies in the Tropics (CAST) campaign.

Extreme cases of precipitation and temperature can lead to extreme events such as e.g. flooding drought and fires, which have the potential to cause large damage as well as disrupt and threaten lives.

In this episode we are "Going to Extremes" and discuss extreme rainfall and flooding events in the UK, as well take a look at extreme events elsewhere on the globe, such as drought and fires in the Americas and Australia and we also touch on the extreme cases of smog in Beijing, China.

As record breaking events are now reported quite often, we delve into the question what role climate change plays in the kind of extreme events we observe and whether they are becoming more frequent.

Finally we reflect on responding and adapting to extreme events and look towards the challenges a changing climate brings.

We mention a lot of different studies and sources of information, please find links to some of them below. Hope you find them useful!

The Great Flood of 1953

UK rainfall and flooding, which has been a big deal over the last years: the New York Times reckons that the combined insurance payout for 2007, 2009 and 2012 floods in the UK was $6.5 billion!

Coverage by the BBC - The science behind Britain's wild weather in 2012

The 2005 Amazon drought was equivalent to more than 80 times the size of Wales in terms of area affected. Second mega-drought was in 2010 with a smaller drought in between 2007. Find the details here:

***Correction for Hurricanes Episode***We said the storm naming was done by the German Weather Service, but it is actually the University of Berlin. Apologies for the error. Find out all about it here on their website

Also apologies for some minor dodgy recording this time round, some syllables and even full words didn't record properly.

sandy_goe_2012302_1745_front.jpgHurricanes have been big news lately after Sandy caused severe destruction and loss of life across the Caribbean and United States of America recently. How do hurricanes (or tropical cyclones) form, what was special about Sandy and was it made worse by climate change? Join the Barometer Podcast team to find out in our latest episode.You can watch the video of Sandy's evolution that Jennifer mentions below:Also you can watch an amazing view of Sandy recorded from the International Space Station below:Header image is taken from NASA's Earth Observatory collection of Sandy images.
