Chinese, Russian and Saudi representatives had the greatest objections to the report. They were opposed to mentions of the level of confidence that the climate was changing. The report projects that African countries could wind up spending five to ten percent of their GDP on dealing with the changes, because of problems like water shortages. Temperatures are predicted to rise by 1.8 to 4 degrees Celsius over the next century, and the melting of Himalayan glaciers could lead to water shortages in the rivers that it feeds. The bottom line of the report is that climate change is real and happening now and needs to be addressed.
