Can you answer the following questions on climate change?
1. Results of modelling for crop yields in the future. Source Rosenzweig and Iglesias, 2002
Changes in temperature, rainfall and carbon dioxide levels alter farming conditions.
The text on "future food production" shows maps which show how crop growth will change.
Use these maps to help you answer the following questions.

a) Extreme heat can cause sterility of pollen.
b) The growth period in Northern Europe will be shorter in the future.
c) Fruits which now only grow in southern countries will soon grow in more northerly regions.
d) As the temperature increases, the yield of some crops will fall.
e) Lack of rain improves agricultural production.
