"We have over the last week seen some progress but progress was slow and uneven," said EU negotiator Peter Wittoeck. "We think that a big effort will still be needed to crystallize options ... in Cancun. Expectations had not been high coming into these negotiations, but U.N. climate chief Christiana Figueres said that despite disagreements, progress had been made in Tianjin. "This week has got us closer to a structured set of decisions that can be agreed to in Cancun. Governments addressed what is doable in Cancun, and what may have to be left to later," she said. Last year's U.N. climate summit in Copenhagen disappointed many environmentalists and political leaders when it failed to produce a legally binding treaty on curbing the greenhouse gases. Scientists have warned that global warming could lead to widespread drought, floods, higher sea levels and worsening storms. Even a 3.6-degree-Fahrenheit (2-degree-Celsius) temperature rise could subject up to 2 billion people to water shortages by 2050, according to a 2007 report by the Intergovernmental Panel on Climate Change, a U.N. network of 2,000 scientists.
