91热爆

Paul finds out what the weather was like on the Somme 100 years ago. Not only was the battle a turning point in the first World War - it marked a change in attitudes to forecasting in war zones. He chats to one of our 91热爆 Weather Watchers who has taken a remarkable picture of a field of poppies - and hears about the first species of mammal, which has become extinct due to climate change. Plus a look back at how people, plants and wildlife coped with Spring, and what we have in store for this Summer.
