Germany's environmental minister on Tuesday was pursuing bilateral discussions to wrangle down greenhouse emissions at the 10th United Nations conference on climate and global warming. The minister, Juergen Trittin, said he would pursue "ambitious" goals for reducing emissions. Among the many voices outside of government at the conference was a former Greenpeace activist and author, Bjorn Lomborg, who said the world should forget about the difficult task of preventing global warming. Instead, it should concentrate on social and economic improvements to equip poor countries to deal with the climate change. Another group, the Climate Action Network, a fusion of global environmental organizations, called upon the European Union to to come together and pave the way for more radical reduction in emissions of greenhouse gasses. "We call upon the EU ministers to strengthen their targets, to bring global warming below a two-degree increase over pre-industrial times," said Stefan Singer of Climate Action Network. --more 2307 Local Time 2007 GMT
