Their contribution to the climate forcing is currently still limited, although steadily increasing from 0. Their contribution is expected to continuously increase in the near future, because of the long lifetimes of most F-gases in some cases more than 1 years and to the increase in the emissions of new HFCs, such as HFCa a substitute of CFCs, as they do not have an ozone depleting impact in the stratosphere.
Indicator specification and metadata Indicator definition This indicator shows the observed trends in greenhouse gas concentrations. Greenhouse gases differ in the way they affect the climate system. In order to sum the effects of the individual greenhouse gases and other forcing agents in the atmosphere, the so-called 'greenhouse gas equivalent concentration' has been defined.
This is the concentration of CO2 that would cause the same amount of radiative forcing as a mixture of CO2 and other forcing agents greenhouse gases and aerosols.
Global average annual concentrations are presented here. Although greenhouse gases are mainly emitted in the northern hemisphere, the use of global average values is considered justified, because the atmospheric lifetime of most greenhouse gases is long compared with the timescales of global atmospheric mixing. This leads to a rather uniform mixture around the globe.
The exceptions are ozone and aerosols. However, as described earlier, these gases are less relevant in the long term. Rationale Justification for indicator selection Greenhouse gases can affect the radiation balance on Earth and are, therefore, crucial for the global climate.
Without these gases, the global average temperature would be about 32 oC lower than it is now i. The various greenhouse gases affect the climate system in different ways. In order to sum their effects on the atmosphere, the so-called greenhouse gas equivalent concentration has been defined.
Get two blocks of wood. Place one block to the far left and one to the far right so that they will support a pane of glass. Carefully place one pane of glass on top of the wood blocks.
Position a second thermometer in the center, on top of the glass pane. Repeat steps 3 and 4. Position the third thermometer to the right on the topmost glass pane.
The result should look like this.
Testing Procedure 1. Have students put their boxes in direct sunlight. Have students read their thermometers and record their data once a day, at the same time.
At the beginning of each class period. Also have students record the classroom temperature. The collected data should be placed in a chart that looks like this 5. Compute the average daily temperature for each thermometer. Discussion Have students examine the relationship between increase in average daily temperature and an increase in the number of panes of glass.
Think about why this is happening. Relate to greenhouse effect. A pane of transparent glass allows solar radiation to pass through, but interferes with the convection that would let heat out.
This is the kind of role that greenhouse gases play in the greenhouse effect: Therefore, in this model, the effect of the increasing number of panes of glass is similar to the effect of increasing greenhouse gas levels. Then have students share how we are changing the natural system of warming with greenhouse gases.
Have students share what they think are the side effects of global warming. They discuss their results and answer questions from the teacher and from the other groups. They prepare an oral report about the experiment in groups and present it to the class and teachers.
What should we do to protect our planet? Brainstorm ideas. Students write a list of possible ideas. Imagine you are a member of a green group and are very worried about greenhouse effect and global warming.
You are going to create a: Poster elementary level Brochure intermediate level Power point presentation advanced level to make people of all ages be aware of these effects.

The Greenhouse Effect Task 1 l Warm up 5 mins Ask the class what they know about the greenhouse effect. Task 2 Vocabulary Write the correct word in the corresponding definition: Electrical tape Room Preparation Have materials ready and glass pre-cut to desired size small enough to just fit into boxes. Closing Ask again: What is the greenhouse effect?
Task 5 Side effects of global warming - Watch these comic strips. Brainstorm ideas about them. In pairs draw a comic strip -Now look at the next picture. Final Project Imagine you are a member of a green group and are very worried about greenhouse effect and global warming.
Vedant Kumar. Gil Mwam. The atmosphere surrounds the Earth. There are gases in the atmosphere such as carbon dioxide or CO2 that act like the glass in the greenhouse they trap the heat. See the picture below.
As the world continues to pollute and damage the environment, there are more and more greenhouse gases being put into the air. This makes the atmosphere trap more and more heat. So the Earth starts to warm up. The use of energy such as petrol in cars and electricity from coal power stations makes more greenhouse gases. This is why many people believe that we have to re-think our use of energy.
Task 2 Vocabulary Write the correct word in the corresponding definition: Global warming fossil fuels solar radiation atmosphere carbon dioxide greenhouse effect greenhouse gases. The air that surrounds the earth. A heavy colorless gas that does not support combustion.
It is formed naturally by the combustion and decomposition of organic substances and is absorbed by photosynthesis of plants. Fuels that are formed in the earth from plant or animal remains. Examples are coal, oil, and natural gas.
The result of the greenhouse effect. It is the warming of the planets atmosphere. Natural global warming is a result of the natural greenhouse effect and is what makes the planet hospitable to life.
Sometimes, "global warming" is used to mean "the greenhouse effect.
