Global Dimming

The Great Mystery

By

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.

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.

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.

Who’s 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 Warming’s Power

• Global Dimming is in fact hiding the power of Global Warming.

• It does this because CFC’s 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 death’s.

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.

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”.

Thank You for Watching

And thank you being a part of our human effort to make our planet a green

one.
