Give examples of extreme weather in the UK 2003 - Heat wave (2000 people died) 2004 - Boscastle flooding 2005 - Dry period
Give evidence that the weather is becoming more extreme 1) Number of floods has increased since the 1960s 2) Climate models show an increase in frequency of extreme events

What evidence is there for climate change? - Global temperatures increasing - Glacier retreat - Arctic ice cover - Ice core samples - Early springs
What is the Greenhouse Effect? Sun radiates down and reflects on the Earth, but is unable to escape to Space and instead gets trapped by the Ozone layer on Earth. This heats up the Earth
