Teacher: Is there heating?
Student: Yes.
Teacher: How much warming?
Student: 0.6ºC last century, 0ºC so far this century.
Teacher: Has the man produced it?
Student: Could be. Something of that warming.
Teacher: How much?
Student: It's hard to say. Almost certainly less than 0.3ºC. The most likely is about 0.15ºC
Teacher: Until where will the warming produced by man go?
Student: It depends on the authors, and depends on whether or not there is feedback to the effect of CO2
Teacher: Explain that.
Student: There are two factors. (1) The direct effect of CO2, and (2) the feedback effect. Depending on the authors, the direct effect can reach, doubling CO2, up to an increase of 1.2 ° C (Hansen, Houghton), or only up to 0.6 ° C more (Monckton), or even only 0.3 ° C (Miskolczy).
Teacher: What is Global Warming?
Student: With this sheet you can mention that human activities (use of fuels for transport and
industry, energy consumption, deforestation, agricultural activity, poor waste management, etc.) produce a large
amount of greenhouse gases, mainly carbon dioxide, increasing its presence in the atmosphere which makes the
Earth retains more radiation and therefore increases its temperature. Remember to mention that this phenomenon is known as
Global Warming, also has to see the Greenhouse Gases exist in the atmosphere naturally, but
human activities, such as the use of fossil fuels and fires
forests, produce an increase in the quantities of these gases, especially
of carbon dioxide (CO2) and methane (CH4).
We call this phenomenon Global Warming, some of the gases are
These gases are:
Water vapor (H2O)
Methane: (CH4)
Nitrogen Oxide: (N2O)
Ozone (O3)
Carbon dioxide (CO2)
these prove the "greenhouse effect"
