Global Dimming

• The Great Mystery

What is Global Dimming?

• Global Dimming is when pollutants mix with water
  vapor and form clouds.
• The clouds formed reflect heat back into space
  thus lowering heat caused by global warming.
• But there is also a bad side to global dimming.

3
The Good Side Of Global Dimming?

• Global Dimming Has several good things about it
  that help us as humans to save our planet.
• First,Global dimming actually hides the power of
  global warming.
• Second,Global Dimming actually prevents the
  temperature from rising to far by blocking heat.

4
Health and Environmental Effects

• The Health and Environmental effects caused by
  Global Dimming is huge.
• For Example, the pollutants Global Dimming uses
  can cause birth defects,coughing,sneezing,itchy
  throat,lung damage,and other unknown symptoms.

5
Whos Fault?

• So whose fault is this entire mess of Global
• Dimming?
• The answer is every humans that burns fossil
  fuels in all ways,indirect or direct.
• The fault is also of plane contrails that form
  miniature clouds that cool the earth because the
  contrails contain pollutants.

Global DimmingHiding Global Warmings Power

• Global Dimming is in fact hiding the power of
  Global Warming.
• It does this because CFCs and other aerosols are
  major contributors to global dimming.
• And since these items have been banned Global
  Dimming has diminished and does not protect
  humanity from Global Warming any longer.

Global Warming vs. Global Dimming

• Global warming Pros
• New emerging technologies.
• New Jobs.
• New Economy.
• The Cons.
• Earth is heating up.
• Damaged to Environment.
• Temperature rising.
• Ozone layers dangerous for mankind.

• Global Dimming Pros
• It Slows down Global Warming.
• Keeps earth relatively cool.
• Aerosol keeps earth cool.
• Cons
• Can cause health problems.
• Severe droughts.
• Flash floods.
• Climate change (Cool or Heat)

The Bad Side of Global Dimming?

• Because of Global Dimming the water in key areas
  have cooled and have resulted into less rainfall.
  This has led to bad crops or droughts for longer
  period in many parts of the world.
• Global dimming has the potential to impact the
  Asian monsoon, the Asian monsoon brings rain fall
  to 3 billion people. If this the monsoon gets
  impacted the Global dimming impact will get
  elevated from millions to billion peoples
  deaths.

So what should we do?

• We as humans need to be balance so that both
  Global warming and Global dimming can be kept in
  control.
• We need to reduce our dependence fossil fuels and
  turn towards green technologies.
• We need to create tighter regulations for
  industries so that gas emitting from factories
  can be reduced or contained to acceptable levels.
  
• We need to create awareness about Global warming
  an global dimming in every part of world.
• We need to protect or natural resources such as
  forest, oceans and snow capped mountains.

10
Why should we donate money to help study Global
Dimming?

• We should donate to Global Dimming because It
  can cause huge droughts and many health effects.
• We should also donate because millions of people
  are affected by us driving to work.
• And the most chilling fact of all, Mother Nature
  is dying and if she dies she takes us with her.

The End

• Thank You for Watching
• And thank you being a part of our
  human effort to make our planet a green one.
