The violence outside has had serious repercussions for events inside the conference hall.
Prevented from entering because of the clashes and heavy security, the fall-out has added to what is already a tense atmosphere as the Brazilian delegation pointed out:
“The representative that is the head of the delegation is outside and the security is not allowing Brazil to be fully representative here,” the conference hall was told by a Brazilian delegate.
“I’ve just asked for your understanding because we are having a very extraordinary situation with security during these hours,” replied COP15 President Connie Hedegaard.
Despite the problems hampering the proceedings, the UN’s Secretary General says he is “reasonably optimistic” that a deal will be reach by the end of the week.
However, Britain’s Prime Minister Gordon Brown has repeated his warning that failure to check global warming may trigger an economic disaster equivalent to the combined effects of the two world wars and the Great Depression.
