International climate negotiations got underway today with dire warnings about climate-driven disasters, pleas to reduce greenhouse gas emissions and a plan for a new global weather early warning system.
The United Nations, which organizes annual climate negotiations, says about 44,000 people are attending this year's meeting in Sharm el-Sheikh, Egypt. That includes leaders from hundreds of nations. They have two weeks to discuss how to dramatically cut greenhouse gas emissions, and pay for the costs of climate change.
