Over time, nuisance flooding can cost more than extreme, infrequent events. In Washington, D.C., for instance, the number of hours of nuisance flooding per year has grown from 19 between 1930 and 1970 to 94 over the last two decades. Projections suggest that there could be as many as 700 hours of nuisance flooding per year by 2050. The UCI researchers found similar potential impacts in four other American cities: Miami, New York, Seattle and San Francisco.
Salty oceans can forecast rain on land. When rain falls over the ocean, the sea surface becomes less salty. At the same time, evaporation makes the sea surface saltier by removing fresh water to the atmosphere. Thus, if a region gets saltier than normal it means that there will be more rain in some other part of the Earth. Similarly, a fresher than normal salinity indicates that the ocean has retained more water and there will be less rain somewhere else. -- 3 month delay
Government authorities say long-term exposure to uranium can damage kidneys and raise cancer risks, and scientists say it can have other harmful effects. In this swath of farmland, roughly 250 miles long and encompassing major cities, up to one in 10 public water systems have raw drinking water with uranium levels that exceed federal and state safety standards, the U.S. Geological Survey has found. More broadly, nearly 2 million people in California's Central Valley and in the U.S. Midwest…
Water containing acid mine drainage can look deceivingly clear when the mineral compounds it carries are still in solution, but clear water can be incredibly toxic. The contaminated drainage can range in pH levels from lemon juice to battery acid. Few organisms survive in it.

SMAP will provide information on soil moisture, which is critical for healthy plant growth, and will help improve crop yield forecasts and irrigation planning around the world. By indirectly monitoring global food production, SMAP will improve targeting of humanitarian food assistance. Studies estimate that climate change will increase the number of undernourished people worldwide in 2080 by 5-26%.
The Sneaky Reason US Coastlines Are Becoming More Polluted
Groundwater could be a major source of coastal pollution. On the other hand, areas with minimal groundwater discharge are susceptible to pollution in the other direction—saltwater invading the land and poisoning our aquifers. As sea levels rise, saltwater intrusion is becoming a bigger problem for low-lying parts of the country, particularly the Miami metro area.
SMAP’s high fidelity measurements of soil moisture will improve flood warnings by assessing how wet the soil is before a rainstorm. Floods are the #1 natural disaster in the United States and they account for 40% of all natural disasters worldwide. Flooding is the leading cause of weather-related deaths in the United States.
