BRUSSELS (Reuters) - The European Commission urged the world on Tuesday to stick with a goal of limiting climate change to a maximum temperature rise of 2 degrees Celsius (3.6 F) after Washington said the target could not be guaranteed.
"World leaders pledged in Copenhagen to stay below the 2C temperature increase. What leaders promised must now be delivered," Commission spokesman Isaac Valero-Ladron said of a 2009 climate summit in the Danish capital.
Almost 200 nations including the United States backed the target that rises in average world temperatures should be below 2C above pre-industrial times, viewed as a threshold for dangerous changes in the Earth's climate.
