* Says Africa can give world clean energy

ADDIS ABABA, Nov 12 (Reuters) - Ethiopian Prime Minister Meles Zenawi, who will represent Africa at next month's Copenhagen climate change talks, said on Thursday it was unlikely the world was serious about tackling global warming.

The United Nations summit in Denmark will try to agree on how to counter climate change and come up with a post-Kyoto treaty protocol to curb harmful emissions.

"It is highly improbable ... the world is serious about climate change and (will decide) to take effective measures to tackle it," Meles told an economic conference in Addis Ababa. "But no one can say such an outcome is completely impossible."

Meles has become Africa's most outspoken leader on climate change and has argued that European pollution may have caused his country's ruinous 1984 famine.
