The impacts of climate change will be widespread across the globe. In order to understand more about what the human impact of high-end climate change might be, and therefore what would happen if a successful agreement can not be reached at Copenhagen, the UK's Met Office Hadley Centre has produced a map outlining some of the impacts that may occur if the global average temperature rises by 4 °C (7 °F) above the pre-industrial climate average. The map represents the latest peer-reviewed science on the impacts.  

Using the map: This interactive version of the 4 degree map allows you to select which impacts you want to see, zoom on specific geographies and access more information about the science behind the map. Click on the map to activate the controls.

Background to Act on Copenhagen

This year is a landmark one for climate change. In Copenhagen in December the world will come together at the United Nations conference to agree a new international agreement to tackle climate change.

The current international agreement, the Kyoto Protocol, will expire in 2012.  The Road to Copenhagen is the UK Government’s case for an ambitious agreement at Copenhagen and focuses on urgent action to limit global temperature increases to no more than 2 degrees Celsius, beyond which the risks of dangerous climate change become much greater.

www.actoncopenhagen.gov.uk is the official UK government website that presents the authoritative HMG position on climate change negotiations in Copenhagen 2009.

With under 100 days to go until Copenhagen it is essential that there is widespread awareness of what is at stake at the Copenhagen talks and of the vital importance of reaching a global deal.
