Fire Sensors
New fire-sensing devices can
spot a fire in its earliest
stages, up to six miles
away, and they can relay the
information to emergency
responders through a
computer network and even
automatically alert people

Predicting Wildfires
Foresters and geographers
have mapped the locations in
the Santa Monica mountains
where the most destructive
fires are likely to start.
To make their map, they
combined data about where
fires were likely to start

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
