Negotiations are underway not to let the talks end up in failure; however, disagreements between industrialized and developing countries are making it difficult to reach a common ground.

UN Secretary General Ban Ki-Moon warned that if the solution is left to the last minute, the talks will end up in a poor agreement, or worse, no agreement at all.

Copenhagen saw the biggest protest of the summit on Wednesday. Reacting to the slow pace of the talks, protestors marched to the building hosting the summit. Police detained 100 demonstrators.

Another crowded march was held to draw attention to the connection between eating habits and global warming. Calling on people to prefer local and natural foods, the protestors said bio-fuels are not better options. Meanwhile, Copenhagen Climate Summit has reportedly caused more carbon emissions than its predecessors.

The math of the experts suggest, flights from 192 countries and the work carried out in Copenhagen will create 46,200 tons of carbon dioxide.

This amount is more than the annual carbon emission output of half the population of Ethiopia.
