The 2011 Great Backyard Bird Count (GBBC) takes place from February 18-21. Each year, bird watchers across the country tally the birds they see in backyards, parks and natural areas. Last year, GBBC participants racked up more than 10 million observations! Counting birds during GBBC helps scientists gain a “snapshot” of North America’s winter bird [...]

Have you ever wondered why potholes appear on roadways during the winter months? Water from melting snow and ice seeps into pavement and the sub-material between pavement and soil below.  When repeated spells of cold weather occur, the water in the pavement refreezes and expands, breaking up the pavement at and below the road surface. When [...]

The Texas Transportation Institute (TTI) recently released its 2010 Urban Mobility Report, which provides information about traffic congestion in 439 urban areas in the United States. Based on 2009 data, TTI estimates that congestion costs 4.8 billion hours of extra time and 115 billion dollars worth of delay and fuel expenses each year. In the Grand [...]

Have you noticed higher energy bills recently? Fewer daylight hours, more time spent inside and chilly temperatures in many parts of the country mean that energy bills are on the rise at this time of year. Luckily, Energy Star has easy-to-use tools to help you assess and reduce the amount of energy used at home.  [...]

January is National Radon Action Month. Radon is produced when uranium in soil, rock and water breaks down and gets into the air. It can be found anywhere in the United States and sneaks into homes and buildings through places like cracks in floors and gaps around pipes. You cannot see, smell or taste radon [...]

December 14 marks the beginning of Audubon’s annual Christmas Bird Count. The Count runs through January 5, 2011. The first Christmas Bird Count (CBC) took place on December 25, 1900 – 27 participants counted and identified about 18,500 birds, mostly in the northeastern U.S. Today, CBC volunteers brave snow and chilly temperatures to identify and [...]

Energy use in the United States typically increases during the holiday season. At this time of year, festive holiday lights that decorate neighborhoods across the country can drive up energy demand and home energy bills. Viewer Tip: Hold on to the holiday spirit while saving energy and money this season. Look for holiday lights that have earned the Energy [...]

 The distinctive smell of wood smoke is a sign of the heating season. It may smell good, but wood smoke can impact indoor air quality and your health. Smoke is a mixture of tiny particles and gases produced when wood burns – the fine particles can get into your eyes and lungs, where they may [...]

Unlike pollution from industrial sources and sewage treatment plants, non-point source (NPS) water pollution comes from many diffuse sources. Polluted runoff is caused by rainwater or snowmelt moving over and through the ground. As the runoff moves, it carries and deposits pollutants – such as fertilizers, pesticides and yard wastes like grass clippings and leaves [...]

The U.S. Energy Information Administration’s (EIA’s) Winter Fuels Outlook uses energy price projections and forecasted weather data from NOAA to predict winter heating bills in the United States. This year, EIA estimates that heating bills may be slightly higher in some regions over the six-month period from October 2010 to March 2011. Heating costs vary [...]

Fewer daylight hours and cooler temperatures mean that many Americans spend more time inside during the fall and winter months. While up to half of the energy used in a typical home goes towards heating and cooling, other home features like water heaters, appliances and lighting contribute to energy bills. Swapping traditional light bulbs for [...]

A recent study by the U.S. Geological Survey found elevated levels of nitrogen and phosphorus in many streams and groundwater supplies across the country. Elevated levels were most often found in streams near agricultural areas, particularly in the Northeast, Midwest and Northwest, as well as near urban areas. In many cases, concentrations of nitrogen and [...]

Did you know that poor quality soil increases the amount of water needed to irrigate lawns and gardens? Soil improvements, such as adding compost or other similar soil amendments, can reduce your irrigation needs by 20 percent. That’s a reduction of more than 16,000 gallons annually per household in states where irrigation is prevalent, or [...]

Wind plays a major role in bird migration. In the fall, wind circulation patterns around highs and lows impact the movement of migratory birds. The ideal time for flying often occurs the day after a cold front passes – north winds, dropping temperatures, rising air pressure and clearing skies are good migration conditions. Soaring birds like [...]

Have you found ladybugs in your home this fall? As temperatures drop, the Asian ladybug, Harmonia axyridis becomes an unwelcome houseguest in many homes. Asian ladybugs invade homes at this time of year searching for protected sites to overwinter. The Asian ladybug is relatively new to the United States – in their native home, Asian ladybugs [...]

One-third of Great Lakes beaches were open less than 95 percent of the time during the swimming season in 2007, the EPA and Environment Canada concluded in last year’s State of the Great Lakes report. The findings were based on data from more than 1,600 beaches. The agencies found that Lake Erie and Lake Ontario [...]

Recent testing of Lake Michigan water has found pharmaceutical byproducts in the water, raising concerns about the potential health threats to people and wildlife for anyone getting drinking water from the Great Lakes. Though many experts say the levels are too low to show immediate effects on human health, scientists acknowledge they know little about [...]

As part of the National Lakes Assessment, the U.S. EPA selected and sampled 148 lakes in the Upper Midwest Region (covering northern and southeastern Minnesota, two-thirds of Wisconsin, northern Indiana and most of Michigan) to characterize the condition of more than 15,500 lakes throughout the area. What did researchers find? More than 90 percent of [...]

Did you know that almost 60 percent of Americans live an area with unhealthy levels of air pollution? Just like a recipe, the atmosphere needs all the right ingredients to make ground-level ozone – a harmful air pollutant that is common during the summer months.  When the temperature rises and the sun is shining, heat [...]

Have you ever wanted to help keep your community by reporting severe weather?  SKYWARN is a volunteer network of nearly 290,000 trained severe weather spotters around the country.  SKYWARN spotters help keep their local communities safe by providing timely and accurate information to the National Weather Service about weather events like thunderstorms, winter weather and [...]
