GLOBAL WARMING
  • Alternate Ideas

16
Global Warming
  • Alternate Ideas
  • Global Heat Island
  • Solar Variation Theory
  • Within Natural Variance
  • Result of Little Ice Age
  • Result of Tunguska Event

17
Urban Heat Isand
  • Raises local temperature
  • Change can be from 2-10F
  • Result of destruction of plant life
  • Concrete, asphalt, man-made objects

19
Solar Variation Theory
  • Suns solar radiation output varies in a
    sinusoidal way
  • Increase of sunspots result in warming periods
  • Decrease in sunspots result in cooling periods
  • Suns magnetic deflects cosmic rays

20
Cosmic Ray
  • Less cosmic rays result in less clouds
  • Cosmic rays ionize air to form clouds
  • Less cloud formation results in higher
    temperature
  • NO ONE KNOWS WHY

21
Solar Variation Theory
22
Tunguska Event
  • Possibly reduced ice crystals in the atmosphere
  • Result in effecting thin layer clouds in
    mesosphere
  • More solar radiation

23
Tunguska Event
24
Natural Variance
25
Little Ice Age
  • Began around 17th century
  • Ended around 1800s
  • Always warming periods after cooler periods

36
This experiment studies droplet clustering in
relationship to droplet size using 3D Holography
techniques.
37
A.C.T.O.S Airborne Cloud Turbulence Observation
System P.I.C.T Phase-Doppler Interferometer for
Clouds and Turbulence A.C.T.O.S is an airborne
device flown by a helicopter that has multiple
scientific instruments attached to it to help us
understand the variable conditions within clouds.

39
ACTOS Collaborated with Institute for
Tropospheric Research(IfT) Which is based out of
Leipzig, Germany. Experiment measured droplet
size and spatial distributions of water droplets
over the skys of Germany.
40
Experimentation of a highly turbulent cloud
Cornell University
20-meter-long wind tunnel Measures droplet
size, speed, and arrival time Uses PICT system
41
Ice Nucleation Research Studies the freezing
of water with a seed Volcanic ash is used to
see how water will freeze Water freezes better
with dust particles Sample is melted and
refrozen hundreds of times to get accurate
data Ice nucleation is still not totally
understood
42
HOLODEC IDEAS3 -Instrument Development and
Education in Airborne Science(phase 3) Held at
the Research Aviation Facility of the National
Center for Atmospheric Research -Uses 3D
Holography to study spatial distribution of water
molecules in clouds
