What is the Montreal Protocol for?

An international treaty designed to protect the ozone layer by phasing out the production of numerous substances believed to be responsible for ozone depletion.

100

Some methods to prevent ozone depletion

  1. Limit private vehicle driving

  2. Use eco-friendly household cleaning products

  3. Avoid using pesticides

  4. Developing stringent regulations for rocket launches

  5. Banning the use of dangerous nitrous oxide

100

How does the greenhouse effect work? 

When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases.

100

What does a decrease in ozone cause?

An increase to the UV rays that reach the Earth's surface.  

100

What does mitigation mean?

The action of reducing the severity of something

200

One reason this protocol was created

Chlorofluorocarbons are strictly man-made and were causing the ozone layer to deplete.

200

Where is the ozone in the atmosphere?

The stratosphere

200

What are greenhouse gases?

Greenhouse gases are the gases in the atmosphere that raise the surface temperature of planets such as the Earth.

200

Exposure to UV rays can cause

Cancer

Some methods to prevent ozone depletion

  1. Limit private vehicle driving

  2. Use eco-friendly household cleaning products

  3. Avoid using pesticides

  4. Developing stringent regulations for rocket launches

  5. Banning the use of dangerous nitrous oxide

300

Some approaches of this treaty:

  • Production Control

  • Consumption Control

  • Trade, Import, export and reimport control ~ Adaptation to Ozone Friendly technology

  • Training and Capacity Building

300

Why is the ozone important?

It is important to the evolution of life on earth. 

300

What is a benefit of the greenhouse effect?

The "greenhouse effect" helps to keep the Earth at a temperature that can support life.

300

How is stratospheric ozone expected to change in the coming decades?

It is expected to recover

300

Has the Montreal Protocol been successful in reducing ozone-depleting substances in the atmosphere? If so, how? 

The Montreal Protocol is working.

There is clear evidence of a decrease in the atmospheric burden of ozone-depleting substances in the lower atmosphere and in the stratosphere;

Some early signs of the expected stratospheric ozone recovery are also evident.

400

When was this treaty opened

1987

400

What causes ozone depletion

The depletion of ozone is largely due to chlorofluorocarbons

400

What has the greatest impact on the greenhouse effect and why?

Carbon dioxide has the greatest overall impact on the greenhouse effect because of its concentration in the atmosphere.

400

 Does depletion of the ozone layer increase ground-level ultraviolet radiation

Yes

400

What is a greenhouse gas that comes only from human sources?

Chlorofluorocarbons

500

Who created the Montreal Protocol

Mario Molina and his partner in research, Sherwood Rowland.

500

Is depletion of the ozone layer the principal cause of global climate change?

No

500

What other than occurring naturally increases concentrations of the greenhouse effect?

Anthropogenic activities. 

500

What reactions cause ozone depletion?

When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules.

500

What are some benefits of HFOs

Hydrofluorocarbons do not have those chlorine atoms attached to it. 

There no chlorine to pop off pop off and to do that catalyst process that breaks down ozone into atmospheric oxygen.
