Despite all the heavy rain in the first half of December, with flood warnings across parts of the state, Wisconsinites should be thankful they did not experience a downpour on the order of 5 inches in just 24 hours. Such extreme rainfall can cause damaging flooding, severe soil erosion and crop loss.

Waterborne pathogens can cycle between the environment and their human and animal hosts, causing illness in people and spreading disease between households. To determine how fecal matter contaminates groundwater, scientists use indicators that specify the source, identifying it as human or animal waste.

One major factor behind the warm Wisconsin autumn is the emergence of an El Niño that is shaping up to be the biggest in nearly two decades.

Leaky sewer pipes might be the source of viruses found in drinking water that Wisconsin municipalities draw from bedrock aquifers 800 feet below ground, research hydrogeologist Kenneth Bradbury said in an Aug. 1, 2012, talk at the Wednesday Nite @ the Lab science series on the University of Wisconsin-Madison campus.
One of the most far-reaching consequences of the 2010 midterm elections was that strong partisan majorities in state legislatures — Republican like Wisconsin and Democratic like Illinois — controlled the redrawing of congressional and state-level electoral districts.
To consider the long-term challenges of climate change and the short-term impacts of powerful weather cycles like the El Niño Southern Oscillation is to face down a wild tangle of variables. This is especially true in agriculture, where weather and climatic variations affect precipitation, temperature, and the timing of planting and harvesting.
Spanish for "The Niño"
The following reports and resources are excellent starting points for grasping the fundamental aspects of ENSO, and opportunities to delve deeper into specific facets of this important and fascinating phenomenon.
El Niño and anthropogenic climate change aren't the same thing, and climatologists stress each phenomenon’s individual effects on weather patterns and occurrences shouldn't be conflated.
An El Niño event can alter economic fortunes worldwide, particularly in agriculture. But other industries can be affected too, including energy, forestry, sales and transportation.
An El Niño winter with warmer temperatures and possibly less precipitation than average could pose a challenge for some Wisconsin recreation and tourism businesses, although many already have been adapting to uncertain winters with less snow.
