Part 6 of United States Climate Change Impact. Precipitation patterns are changing Precipitation is not distributed evenly over the globe. Its average distribution is governed primarily by atmospheric circulation patterns, the availability of moisture, and surface terrain effects. The first two of these factors are influenced by temperature. Thus, human-caused changes in temperature are expected […]
Part 2 of United States Climate Change Impact. Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases. These emissions come mainly from the burning of fossil fuels (coal, oil, and gas), with important contributions from the clearing […]
With the weight of scientific data pointing to the changes in the environment due to increasing concentrations of greenhouse gases—called climate change—the U.S. Fish and Wildlife Service (Service) has begun monitoring and analyzing impacts of climate change on fish and wildlife and working toward solutions to help species adapt to their changing habitats. Representing a […]
The surveys indicate that Americans are concerned about the environment, global warming, and related topics. Yet many do not realize that cars and trucks that guides are an important source of these problems, and that there are other choices they can do today. Most of us drive or ride vehicles that are powered by petroleum-based […]
