Treaty Elements In 1992, more than 160 nations adopted the United Nations Framework Convention on Climate Change (7). Its main elements included acknowledgment of the science of climate change; establishment of a long-term objective: preventing "dangerous anthropogenic interference with the climate system"; division of responsibilities between industrialized and developing countries; and, acceptance by industrialized countries of a nonbinding goal: returning their emissions to 1990 levels by the year 2000.
In the years since 1992, the international community has grappled with many of the complex issues presented by growing GHG emissions and has worked to develop a more specific, binding regime. Yet in most countries, emissions have increased.
One question that has arisen recently is whether emissions reduction commitments should await additional work to define a safe concentration level for GHGs in the atmosphere (8). We believe not. Today, GHG concentrations are greater than at any time in the last 420,000 years (1). Absent a reduction in projected emissions, concentrations by 2100 will reach levels not seen in 40 to 50 million years (9). Given the long atmospheric lifetime of most GHGs, concrete steps to curb emissions are justified in the short term. Further research on the impacts of different atmospheric GHG concentrations is important, but should not become an excuse to defer short-term action to reduce emissions.
