We live in a litigious society. Engineering and environmental geologists are no strangers to the legal system. They frequently deal with issues relating to geologic hazards such as active faults and unstable ground, the release of contaminants into the environment and numerous other circumstances. But for the most part, geoscientists tend to avoid legal battles. Is that changing?
“This is the way it was.” Or: “This is what is happening.” Hmmm. Scientists don’t usually make such definitive statements, given that in science, there are almost always caveats. Yet in the last year, such statements have been issued by several large groups of scientists who have come together to support a certain point of view. Are scientists feeling the need to dig in their heels because of public pressures? Or are we actually reaching some consensus?
Humans have harnessed wind energy throughout history for milling, pumping and transportation — in a way you could say it’s the “original” form of industrial energy. But only recently have we built massive, powerful turbines to convert that wind into electricity. As concerns about pollution, carbon emissions, resource depletion and energy security mount, wind farms are an increasingly attractive alternative for meeting growing energy demand.
Winter is hard on asphalt: Water that seeps into tiny cracks freezes and expands, breaking the asphalt apart. That’s why homeowners and business owners across the U.S. use sealants to protect their driveways and parking lots.
