130 Years of Earth Surface Temperatures
Explanation:
How has the surface temperature of Earth been changing?
To help find out,
Earth scientists collected temperature records from over 1000
weather stations around the globe since 1880, and combined them with modern
satellite data.
The
above movie
dramatizes the result showing 130 years of
planet-wide temperature changes relative to the local average
temperatures in the mid-1900s.
In the
above global maps, red means warmer and
blue means
colder.
On average,
the
display demonstrates that the
temperature on Earth has increased by nearly one degree
Celsius over the past 130 years,
and many of the
warmest years on record have occurred only recently.
Global climate change is of more than passing
interest -- it is linked to global
weather
severity and coastal
sea water levels.
