US Emissions Bill A "First Step" - UN Climate Chief
- A bill going to the US Senate next week seeking deep cuts in US greenhouse gases by 2050 is a "first step" but not enough to avert damaging climate change, the head of the UN Climate Panel said on Friday. Rajendra Pachauri also said that even tougher plans by some other developed nations to rein in emissions were insufficient to head off some projected impacts of global warming, ranging from more heatwaves and droughts to rising seas.
