The concentration of 'Kyoto gases' reached 438 ppm CO2-equivalent in 2008.
By 2100, the concentration of 'Kyoto gases' is projected to increase to 638-1360 ppm CO2-equivalent.
The decade 2000-2009 was the warmest on record. Europe has warmed more than the global average.
By 2100, ocean acidity could be higher than during the past 20 million years.
The third lowest minimum of Arctic summer sea ice occurred in September 2010.
In 2007, the IPCC projected a sea level rise of 0.18 to 0.59 m above the 1990 level by 2100.
Recent projections show a maximum increase of sea level of about 1.0 m by 2100, while higher values up to 2.0 m cannot be excluded.
