Three line graphs captioned 'Change in global land-surface air temperature', 'Change in mean global sea ice' and 'Change in global sea level.' These three graphs reflects following information:

1. Change in Global Land-Surface Air Temperature since 1850 to 2005. x-axis representing the Land-Surface temperature change degree Celsius and y-axis represents the years from 1850 to 2005. The line graph is shown increasing steadily.
2. Change in mean global sea ice since 1953 to 2007. x-axis representing the extent of change and y-axis represents the years from 1953 to 2007. The line graph is shown decreasing steadily.
3. Change in global sea level since 1870 to 2005. x-axis representing the sea level change in millimeter and y-axis represents the years from 1870 to 2005. The line graph is shown increasing steadily.
