MAINSTREAMING CLIMATE CHANGE ADAPTATION IN AGRICULTURAL EXTENSION
SLIDE 15 – Predicted effect on temperature
This graph shows the predictions in colour form and for the different parts of the
world
SLIDE 16 – Predicted effect on sea level rise
This shows the amount that the sea level is predicted to rise before 2100. Sea level
rise is caused by the ice caps melting and by expansion of the sea with temperature.
SLIDE 17 – Predicted effect on precipitation
Much more uncertain due to the complex weather systems on Earth
- Some areas expected to get wetter & some drier but climate models
disagree about regional effects.
- A warmer atmosphere in general will intensify the water cycle, leading to
more intense storms.
- This is the cutting edge of climate science!
SLIDE 18 – Predicted effect on precipitation
This slide shows the predictions for changes in precipitation. The darker the brown
colour the greater the reduction in precipitation. The darker the green colour the
greater the increase in precipitation (see the key on the right hand side).
Notice that you have three graphs in the top line. Going from left to right the graphs
are for total rainfall for a) a whole year b) December, January, February c) June,
July, August. The key on the right hand side
The bottom row of graphs show how much the different model predictions of what
will happen agree / disagree with each other. The areas in white show areas that
none of the models agree with each other. Precipitation is difficult to predict.
