Having had such success with the original “
4 Degree Map” that the United Kingdom launched last October, my colleagues in the
UK Foreign and Commonwealth Office have been working on a Google Earth version, which
users can now download from the Foreign Office website.
This interactive map shows some of the possible impacts of a global temperature rise of 4 degrees Celsius (7° F). It underlines why the UK government and other countries believe we must keep global warming to below 2 degrees Celsius, compared to pre-industrial times; beyond that, the impacts will be increasingly disruptive to our global prosperity and security.
In my role as the UK’s Climate and Energy Security Envoy I have spoken to many colleagues in the international defense and security community about the threat climate change poses to our security. We need to understand how the impacts, as described in this map, will interact with other drivers of instability and global trends. Once we have this understanding we can then plan what needs to be done to mitigate the risks.
The map includes videos from the contributing scientists, who are led by the Met Office Hadley Centre. For example, if you click on the impact icon showing an increase in extreme weather events in the Gulf of Mexico region, up pops a video clip of the contributing scientist Dr Joanne Camp, talking about her research. It also includes examples of what the UK Foreign and Commonwealth Office and British Council are doing to increase people’s awareness of the risks climate change poses to our national security and prosperity, thus illustrating the FCO’s ongoing work on climate change and the low-carbon transition.
