Merkel calls for int'l efforts on climate change

In Washington, German Chancellor Angela Merkel is urging the international community to take common action to fight against climate change, saying there is "no time to lose."

In a speech to the US Congress on Tuesday, Merkel called on the international community to reach an agreement on preventing global warming at a UN conference in Copenhagen in December. She noted that an agreement should be reached on realizing this objective: global warming must not exceed 2 degrees Celsius. On the same day, Merkel met with President Barack Obama in the White House. They reaffirmed the U.S.-German alliance on dealing with common challenges ranging from climate change to nuclear non-proliferation.
