We will investigate…….• Looking at the severe Tornado outbreak in
America (Mid-West April 2011)TORNADO ALLEY
This area of the USA is prone to Tornadoes every spring.
The above map shows the locations of all the tornadoes that touched down on the 28th April 2011

• Return back to your seat and write down as much as you can remember!
• Next person comes up and the process repeats 2 times.• All groups will then take part in a quick quiz on the
SUPER OUTBREAK to see who is the best journalist team

Does Climate Change mean more deadly tornado Outbreaks?
• Unfortunately, there will be more massively deadly tornado outbreaks in the future. With populations growing in tornado-prone areas, there is an increasing risk of future outbreaks causing loss of life.
• The NWA emphasizes that no single series of tornado events should be construed as evidence of a climate trend. However warming trends do create more of the fuel that tornadoes require, such as moisture
Trends in tornado activity
Since 1975 the trend shows a decline in the number of strong tornadoes recorded.
Does this fit in with the belief that extreme weather is on the increase?
So….. Will we see more tornadoes deaths as a result of climate
change?• Success criteria:
Include a balanced answer (points that agree, and disagree)
Case study detail (figures, place names)
Task: create a 60 second news report on the SUPER OUTBREAK
• You are a major news Reporter on the BBC and have a 60-second update slot in which to tell the world about the American outbreak.
• In groups of 4, prepare you report and practise delivering it. These will be shown to the class at the end.
