Water research during the late 1970s and 1980s indicated that stormwater runoff was a significant cause of water quality impairment in many parts of the US. [24] Research on stormwater pollution continues in the 21st century, with findings that urban runoff is a ongoing source of water quality problems nationwide.
There have been as many as 48 recessions in the United States dating back to the Articles of Confederation, and although economists and historians dispute certain 19th-century recessions, [1] the consensus view among economists and historians is that "The cyclical volatility of GNP and unemployment was greater before the Great Depression than it has been since the end of World War II." [2 ...
Further, fiscal and monetary policy did not seem to be possible causes. Changes in tax policy had little impact; for example, Clinton raised taxes while Reagan cut them, but both had strong growth. Interest rates had typically risen under Democrats and fallen under Republicans, which theoretically should have favored Republicans.
Environmental impact of reservoirs. The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water, generate hydroelectric power, increase the water supply for irrigation ...
Monetary policy works by stimulating or suppressing the overall demand for goods and services in the economy, which will tend to increase respectively diminish employment and inflation. The Federal Reserve's primary means to this end is adjusting the target for the Federal funds rate (FFR) suitably. [4] Changes in the Federal funds rate targets normally affect the interest rates that banks and ...
The higher the deficit, the riskier it becomes to hold US debt, which tends to grow when the deficit does. As a result, the government could have to pay higher interest rates to borrow money.
This can cause decreased water quality and lead to an expensive desalination effort to clean the water before distribution. Water flows through wildlife refuges and national parks can decrease or stop all together due to the decrease of surface and groundwater, the California Water Science Center is a part of a team trying to restore and ...
The effects of climate change on the water cycle have important negative effects on the availability of freshwater resources, as well as other water reservoirs such as oceans, ice sheets, the atmosphere and soil moisture. The water cycle is essential to life on Earth and plays a large role in the global climate system and ocean circulation.
