A recent analysis of 15 global climate models found certain predictions consistently across all the models . Across the globe , from Chile to China and Scotland to South Africa , farming of salmon , shrimp , mussels , oysters and clams is increasingly common . During the years of the Lewis and Clark expedition , Major Zebulon Pike led two parallel expeditions through other parts of the Louisiana Purchase , the first to the source of the Mississippi , and the second westward , and across into Mexican territory . The International Organization for Standardization ( ISO ) 14001 standard , first published in 1996 , specifies the actual requirements for an environmental management system in organizations ( companies and institutions ) , with the goal of minimizing harmful effects on the environment and achieving continual improvement of its environmental performance . Predictions of wetter soils were highly consistent across the models only for Northern middle and high latitudes , and only during non-growing seasons . Despite rising oil prices , the impact of severe natural disasters and the threat of bird flu , the region made significant progress towards achieving the Millennium Development Goals . Studies in India and China , for example , show that the percentage of fuel carbon fully burned to carbon dioxide is typically only 90 per cent , with some fuel / stove combinations only achieving 80 per cent . EMIs are authorized to carry out a range of enforcement powers varying from routine inspections to search and seizure operations , setting up roadblocks and arresting suspects . We have used both imagination and science as ingredients for generating effective scenarios , and we have made quantitative assumptions across a range of dimensions : eco-nomic growth and struc-ture , popula-tion , technology , resources and the environment .
