The document discusses issues related to the upcoming Copenhagen climate change conference. It notes that estimates for the disappearance of summer Arctic sea ice have been reduced to as little as 5 years from now. There is a disparity between reductions proposed by developed countries, which are 16-24% below 1990 levels by 2020, and least developed countries which are calling for at least 45% reductions. The costs of climate change mitigation and adaptation are estimated at $90-140 billion per year. In preparation for Copenhagen, efforts will be made to enrich analysis, bring ecosocialist demands into electoral programs, and build mass movement on the issues.
