In the Rosebud River valley, an hour east of Calgary, the water in many homes can be lit on fire. Everyone agrees there's gas in the water. Few agree on why. At Fiona Lauridsen's farm, just outside the hamlet of Rosebud, showering has become a dangerous activity. Fiona and her family developed skin burns from simply taking a shower and Fiona claims that EnCana, Canada's largest natural gas company is responsible. She claims that EnCana has contaminated the aquifer by drilling (fracking) for coal bed methane, a new source of natural gas extraction that often uses chemicals for drilling. Yet in the hamlet, where the Rosebud Theatre is a popular tourist attraction and graciously sponsored by EnCana, most residents refuse to even talk about burning water, for fear of harming the tourist industry.

Rented by the BP Oil Company to drill an oil well in the Gulf of Mexico, the Deepwater Horizon drilling rig explodes on April 20, 2010. It sinks into the ocean and causes a gigantic oil spill. At issue is negligence in the maintenance and in the tests carried out. On September 19, after months of unsuccessful attempts, the spill is finally declared sealed. However, this incident has generated the largest marine oil disaster in history. Part of the "Butterfly Effect" series.
Space weather can have important consequences for everyday life, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation. The United States Geological Survey (USGS) Geomagnetism Program monitors variations in the Earth's magnetic field through a network of 14 ground-based observatories around the United States and its territories, providing data in real-time to a variety of customers.
In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But questions about its impact on the air and water are far from settled. With support from the National Science Foundation, University of Colorado environmental engineer Joseph Ryan heads a team gathering data on the pros and cons of oil and natural gas development, including the use of hydraulic fracturing. Part of the National Science Foundation Series “Science Nation.”
Everywhere one looks in Southern Louisiana there's water: rivers, bayous, swamps, the Mississippi River, and the Gulf of Mexico. And everyone in Cajun Country has a water story, or two or three or more. Its waterways support the biggest economies in Louisiana - a $70 billion a year oil and gas industry, a $2.4 billion a year fishing business, tourism and recreational sports. But these waterways are also home to some insidious polluters along a 100-mile-long stretch of the Mississippi known "Cancer Alley," the world's largest Dead Zone in the Gulf of Mexico and erosion that is costing the coastline twenty five square miles of wetlands a year.
