Figure 1: The World with a Global Temperature Rise of 4°C
In order to understand more about what the human impact of high-end climate change might the 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.
Although the average temperature rise over the globe is 4 °C (7 °F) the projection on the map shows that this average rise will not be spread uniformly across the globe. The land will heat up more quickly than the sea, and high latitudes, particularly the Arctic, will have larger temperature increases. The average land temperature will be 5.5 °C above pre-industrial levels.
The map was produced by the Met Office (on behalf of HM Government), but contains contributions from climate scientists from other institutions conducting the latest research on climate impacts.

Figure 6: Yokohama
In 2007 the administrative district of Yokohama, Japan, emitted almost 20 million tons of CO2. Aiming to become a low-carbon city, it set a goal to reduce CO2 emissions per person by at least 60 percent, relative to the 2004 level, by 2050. With a population of almost 3.7 million, Yokohama has been continuously degrading and converting its forests and farmland. The consequence has been a demonstrable impact on the city's microclimate, above that associated with global climate change, resulting in an urban heat island effect. The increase in buildings and paved surfaces has enhanced the city's heat-absorption capacity and increased its reflective heat, thereby raising temperatures.
