Nigeria's Minister of Environment John Odey in Copenhagen urges his African colleagues to remain resolute and committed to the African Group's demand on climate change, local media reported on Thursday.

He urged the African ministers of environment and water during one of their strategic meetings to ensure that they work toward a common goal and show absolute commitment.

Odey said Africa must also deliver now, not only because of its peculiar climate challenges but because Africa's situation and that of other 600 million people in the world, who are already vulnerable because of climate change.

He warned that the world is set to see more extreme weather conditions such as droughts, floods and typhoons, urging participants to watch out for clandestine moves to kill the Kyoto Protocol.

The minister said majority of the countries attending the climate talks in Copenhagen wanted the continuation of the Kyoto Protocol.

"It is in the interest of all that the ongoing UN climate conference proceeds on two tracks; one under the Kyoto Protocol, while the other focuses on longer term and broader issues," the News Agency of Nigeria quoted him as saying.

Meanwhile, the UN climate conference has entered its decisive phase as the heads of state and government began to arrive in Copenhagen.

The leaders will be facing a defining moment in history, as the UN Secretary-General Ban Ki-moon said on Tuesday.

"We know what we must do. We know what the world expects. Our job here and now is to seal the deal, a deal in our common interest," he said.
