'There will not be a major deal at Copenhagen summit'

"The gap between developed and developing countries on climate change is too wide. So, I feel that there won't be a major agreement," Mohan Munasinghe, vice-chairman of the Noble peace prize winning UN Intergovernmental Panel on Climate Change said.

The major issues that remain the bone of contention for any breakthrough on climate change pact include disparities between the two worlds when it comes to global warming and greenhouse gas emissions.

The climatologist said the developing countries (G-77+China) have been asking the industrial nations to cut emissions by 40 per cent till 2020 whereas they (developed nations) are ready to cut emissions by 15-20 per cent and hence the differences remain.

The UN framework Convention on Climate Change also views reductions in emissions to be largely the responsibility of the industrialised countries.
