EC238 Lecture Notes - Lecture 20: Earth Summit, Ocean Acidification
Document Summary
The intergovernmental panel on climate change (ipcc) is the body charged with assessing the scientific evidence on climate change. Ipcc reported in 2007 that most warming over last 250 years can be attributed to human activity. Human-induced warming and sea-level rise will continue for centuries, even if stabilized: it is extremely likely that human influence has been the main cause of global warming during the last century. Scientists agree that rising ghgs will affect climate. Uncertainty is about when this may happen and the extent of effect. =an agreement reached at the 1992 rio summit that dealt with global warming and other air quality issues. Called for nations to implement national strategies to limit ghg emissions with the objective of reducing emissions to 1990 levels by 2000. Avoided uniform emissions targets to accommodate differences in political and economic conditions. Encouraged signatories to recognize climate change in devising economic, social, and environmental policies.
