Fuel, heat, and oxygen form what is known as the “fire triangle.” With these elements in place, all that is required for a fire to start is an ignition source, such as lightning or a match. A fire’s intensity is determined by a variety of factors including the amount of available fuel (trees, grasses, leaves [...]

Earth’s climatic energy is moving all about us in different forms. Rain falling on us and rushing through rivers back into the ocean is one form. Big ocean currents, like the Gulf Stream, are another form of climatic energy. Energy coming in directly from the sun (shortwave radiation) warms the Earth’s surface and to a [...]

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 Phoenix [...]

Michael Halpert, deputy director of the Climate Prediction Center at the National Oceanic and Atmospheric Administration (NOAA), and Greg Butcher, director of bird conservation for the National Audubon Society were the featured speakers of Earth Gauge’s December webinar. Halpert discussed the 2010-2011 Winter Outlook, how seasonal forecasts are made and the influence of La Niña [...]

In Brief: From January 2000 to October 24, 2010, 310,531 record high temperatures were set across the contiguous United States. During the same period, 152,087 record low temperatures were set, giving a record highs to record lows ratio of more than 2:1. There are close to 5,000 quality-controlled weather stations across the United States and [...]

This is the time of year when lawn activities peak – watering, fertilizing and mowing.  All of these activities can have environmental impacts.  For example, did you know that over 50 million Americans mow their lawns each weekend and contribute as much as five percent of the country’s air pollution?  Viewer Tip: You can have [...]

Tips from Joe Witte, meteorologist at NewsChannel 8, Washington, DC, and Earth Gauge media consultant. An easy way to show Earth Gauge videos on-air: Use your ScanDo Play videos directly on-air via the computers you have right now.  Both your WeatherBug and Doppler computers pump their images to “air” via a ScanDo. During “quiet weather” [...]

The Deepwater Horizon Spill After the April 20th explosion on Deepwater Horizon off-shore exploration well, thousands of gallons of crude oil leaked from the seafloor each day. A combination of floating barriers, chemical dispersants and controlled burns were used to mitigate and control the spill. The spill continues to threaten Gulf of Mexico wildlife and [...]

Thanks to lower fuel prices and expectations for a slightly milder winter, the Energy Information Administration (EIA) projects that households in the U.S. will spend less on heating fuel this winter compared to last year. In the South, where over 59 percent of households use electricity for heating, EIA projects that households will spend about [...]

Over the past four decades, there has been a planet-wide lengthening of the “green” period between leaf emergence in the spring and leaf drop in the fall, which is now about 15 days longer than it was in 1970. This lengthening has been linked to the planet’s warming trend. Just as changes in climate can [...]

Seabirds, such as auks, gulls, petrels, terns, and gannets, have spent tens of millions of years adapting to life on the ocean. Some species, such as the Sooty Tern, can spend years at sea before returning to land. The success of these species is dependent on the success of their food sources (such as fish [...]

During the warm seasons (spring through fall), the water in the Baltic Sea is stable and stratified. This means that the warmest and least dense water is on the surface, and as you dive deeper and deeper, layers of progressively colder, saltier, and denser water are encountered. During the decades of the 1970′s and 1980′s, [...]

Polar bears, Earth’s largest land predator, are most common on annual sea ice that sits over shallow seas. This ice provides the bears with a platform from which they can hunt for food. In Canada’s western Hudson Bay region, which is at the southernmost extent of the polar bear’s range, winter and spring are the [...]

The world’s largest and oldest lake, Russia’s Lake Baikal, provides habitat for over 2,500 species, most of which are found nowhere else on Earth. Baikal has changed rapidly over the last 60 years. These changes include a two degree Fahrenheit rise in the temperature of the water, a corresponding 300 percent increase in chlorophyll concentration in [...]
