 Climate Change and Climate Models

 Purpose:

The overall purpose of this paper is to present ideas for working with “Climate Change and Climate Models”. This is one of eight themes chosen as focal points in connection with the Zealand Consensus Project, which is to be the presentation of the students to the decision makers of the world at COP15, Copenhagen 2009.

 

The 8 Themes:

1.      Climate Change and Climate Models

2.      Bio Fuel

3.      Hydrogen Energy

4.      Renewable Energy

5.      Environmental Behaviour – Housing, Traffic and Transportation

6.      Burning of Waste

7.      Nuclear Energy

8.      GMO

Introduction:

Experts on climate from around the world agree that the climate changes extremely rapidly during the present time. According to several scientists on the UN Intercontinental Panel on Climate Change (the IPCC) it will still be possible to limit this increased warming to just 2-3 degrees (Celsius) over the next 100 years, if we actively begin slowing down the outlet of green house gas today. Immediately it may sound quite nice with a few extra degrees in Denmark, but the rise in temperature is a global average. That means that temperature may only rise ½ degree in Denmark, whereas it will rise 5 degrees or more in other places.

Some of the visual consequences of this global warming can already be seen at the Poles and at certain glaciers where an increased melting can be registered. When the Poles and great glaciers melt, it means that the levels of the oceans are rising and that can cause serious floods and danger that great areas of land will disappear. Another unpleasant consequence of global warming is that the weather becomes more extreme (hotter, wetter and wilder) causing increased areas with draught, violent showers and more fierce storms and hurricanes. Furthermore the increased temperature in Denmark will mean that we shall begin to see harmful insects in the Danish nature like malaria mosquitoes.

This increased global warming is caused by the green house effect. This effect is caused by green houses gas like ex. CO2 (carbon dioxide), CH4 (methane) and NO2 (laughing gas). Green house gas effectively holds back the heat of the Earth – like a green house holds the heat. In order to maintain a level of heat befitting life on Earth, a certain amount of green house gas is needed, but it is a subtle balance demanding not too much green house gas in the Earth’s atmosphere. Green house gas is created by the burning of oil, gas and coal and by the raising of cattle.

Thus some of the questions or challenges of the future will be: How much are you willing to bring down your own energy consumption and your consumption of meat? Can developing countries develop, if they have to save energy at the same time? Are the developing countries to be allowed increased energy consumption, while we hold back simultaneously in the rich countries? Are we to ban the use of gas guzzlers like 4 wheel drivers and giant garden pools? The conclusion is that most people seem to agree that the world is to decrease the amount of green house gas especially CO2 – but how is that done, exactly?

 Focus:

In the subject of ‘climate change’ you find aspects of causes as well as aspects of effects. It is obvious to work with natural causes as well as man-made ones in the climate change of the past and the present as well as attempting to describe the climate of the future based on various climate models. In this context it may prove expedient to include negative and positive feedback systems concerning Earth’s ability to regulate temperature - not to mention the level of carbon dioxide in the air.

Climate change can be regarded both as a result of global warming (ex. melting of Poles, increased water level in the oceans, higher temperature, heavier rainfalls and storms) and as a result of the increase of the contents of carbon dioxide in the air, which ex. also has an impact on the acidity of the oceans. Furthermore concrete consequences of climate change for fauna and vegetation can be studied.

 

 Educational deliberations:

Basic (all students):

bulletBasic platform securing the students minimum of knowledge concerning the complex of environmental problems
bulletWhat decides the climate of Earth
bulletGreen house effect
bulletGreen house gas – natural and man-made
bulletFuture climate
bulletClimate models and their complexity (briefly)
bullet Consequences of climate change
bulletExtreme weather conditions
bulletProduction of food
bulletMelting of the ice caps and increase of water levels
bulletImpact on fauna and vegetation
bulletWater resource

Subject no. 1: The Effect of Climate Change (Workshop 1)

The intention is for all students to get an insight into the       

many consequences it may have when the climate changes with the temperature rising just a few degrees – from a biotic as well an abiotic point of view.

 Subject no. 2: The Effect of Climate Change on Society (Workshop 2)

The intention is for students to get an insight into the local as well as global consequences for society when the climate changes drastically. Furthermore to make students see the many difficult choices of climate politics:

How to go about doing something and how to do it most effectively. Here the point is also to be introduced to methods of environmental decision making.

 Subject no. 3: The Reduction of the Outlet of Green House Gas – Locally and Globally (Workshop 3)

Under this heading the intention is for the students to get insight into what is going on globally through the UN as well as working with possible local initiatives to diminish one’s own consumption and the discharge of CO2 following from it.

 Subject no. 4: Climate Models and the Climate of the Future (Workshop 4)

Under this heading the intention is for the students to see how the models are structured and which many factors they are to take into account. Furthermore to make them see how it will also be necessary to make models for the discharge of CO2 in the future.
