Our Changing Climate
Geographers have projected
temperature increases due to
greenhouse gas emissions to
reach a not-so-chilling
conclusion: climate zones
will shift and some climates
will disappear completely by
2100. Tropical highlands and

Mysteries of Thunderstorms
Satellite imaging is now
helping atmospheric
scientists link the amount
of charged ice in clouds to
lightning activity. Ice
particles in thunderstorms
can help increase

Growing Greener Lawns
Chemists and engineers
designed a technology that
protects soil. A polymer
encased in recycled paper
bonds to positive ions in
soil to form clumps. These
clods of dirt break up the
hard surface that can form

El Nino's Return
Researchers are using
satellites in efforts to
better predict El
Niño, the weather
pattern responsible for
supplying more moisture and
energy to storms in the U.S.
during the winter season. El

Meteorologists Track Tornado Damage From Satellites
Meteorologists use high resolution satellite photography to analyze the path and intensity of recent tornadoes. The data obtained allows them to develop a mathematical model to identify storm damage ... > more -
Seismologists Find Large Earthquakes Can Trigger Smaller Ones In Unlikely Locations
Seismologists found that L-waves, slow-moving seismic surface waves, from larger earthquakes can trigger smaller earthquakes as they travel through the ground. Different from aftershocks because ... > more -
New Software Helps Track the Path of Toxic Spills
Ecological engineers have developed software that can model the path of a toxic spill in waterways anywhere in the United States. The system can predict if and when a contaminant will reach a ... > more -
Atmospheric Scientists And Meteorologists Use Driftsondes For Hurricane Forecasts
For decades, meteorologists have launched balloons to measure and track weather patterns. Now, these balloons are helping tropical forecasters better pinpoint the motion and severity of forming ... > more -
Meteorologists Find That Increased Ocean Temperatures Cause Increasingly Intense Hurricanes
Climate change experts studying hurricanes documented a 35-year warming trend in ocean surface temperature and linked it to larger hurricanes. The increase has been 1 degree Fahrenheit, resulting in ... > more -
Meteorologists, Atmospheric Scientists Fly Through Storms to Gather Data
During hurricane season, scientists fly aboard NOAA aircraft to pinpoint the precise path of the eye of a storm, and to take data to send back to the National Hurricane Center. The planes are now ... > more -
