Created with contributions from a number of universities and government and scientific organisations, the map illustrates a wide range of effects, from the impact on the global economy as changes in crop yields damage trade, to the increase in the frequency and duration of droughts. Among the potential impacts illustrated are: temperatures on the warmest days rising by 6°C in parts of the world; sea temperatures rising by up to 4°C; maize yields falling by up to 12 per cent in Central America; and millions of people flooded, particularly in Asia.
‘We know that rising sea levels are having profound impacts in many parts of the world,’ said Sally Brown of the University of Southampton, who contributed data on sea level-related flooding. ‘We hope that this tool will help scientists and governments better understand the threat that climate change poses to our collective future prosperity and security.’
‘We’ve used the latest science to assess how changes in our climate will impact people around the world,’ said Dame Julia Slingo, the Met Office chief scientist. ‘While we see both positive and negative impacts, the risks vastly outweigh any potential opportunities.’
