> Current CO2 concentrations have not been exceeded in the past 650,000 years and probably not in the past 20 million years
> The global mean sea-level rose by 1-2mm annually in the 20th century. It will continue to rise due to glacial retreat on Greenland and Antarctica as well as thermal expansion of the ocean as ocean temperature increases
> Global average temperature has increased by about 0.74 degrees centigrade over the 20th century
> Eleven of the last twelve years (1995-2006) rank among the 12 warmest years since the instrumental record of global surface temperature began in 1850.
