“On December 1, 1997, delegates from more than 150 nations arrived in Kyoto, Japan, to attend the Conference of the Parties to the United Nations Framework Convention on Climate Change. They met to devise the first international treaty on ways to reduce the emission of carbon dioxide gas into the atmosphere. Carbon dioxide is a gas that is released when such fuels as coal, gasoline, and wood are burned. In the atmosphere, it serves as a sort of one-way windowpane, like the glass in a greenhouse. The sun’s radiation passes down through the windowpane to warm the earth. Some of the heat from the earth’s surface is radiated to the atmospheric windowpane, however, and is trapped on the earth, creating a greenhouse effect.
After the Kyoto convention, the delegates discussed the results of a two-year negotiation process that followed the Earth Summit in Brazil. The final treaty, known as the Kyoto Protocol, laid out a specific strategy for combating global warming. This strategy required 38 industrialized nations to reduce their combined greenhouse-gas emissions to more than 5 percent below 1990 levels. Developing nations, which release fewer carbon dioxide gases into the atmosphere, could set their own limits on such emissions. Those industrialized nations that were unable to meet the limits set for them could apply for emission-reduction credits from industrialized nations that achieved reductions greater than that called for by the treaty. Since forests absorb large quantities of carbon dioxide, industrialized nations could receive emission credits by planting new forests and protecting existing ones.
U.S. lawmakers who attended the conference stated that the U.S. Senate would never ratify the Kyoto Protocol. Opponents of the treaty argued that to cut the use of carbon fuels to the extent it required would cause energy prices to soar and would damage the U.S. economy.” ~ Global History: The Growth of Civilizations
Questions:

______
4-How did the Kyoto Protocol attempt to reduce carbon emissions? ______
5-Why did the U.S. not sign the Kyoto Protocol? ______
Notes:
- Global Warming
- The earth has experienced climate change
- But, starting with the Industrial Revolution, human activity has increased this change
1-Burning of fossil fuels – coal and oil
2-Deforestation –cutting down trees
3-Leads to “greenhouse gases”
4-“Greenhouse gases” trap heat
5-Raise earth’s temperature above past levels
- Deforestation
- More than 80% of the Earth’s natural forests have been destroyed
- Due to logging, fires, and clearing land for agriculture
- Trees are natural consumers of carbon dioxide
1-One of the greenhouse gases
- Desertification
- Deserts are expanding
- Due to deforestation, overgrazing, over cultivation
- People displaced
- Hunger and Famine
- Reduce, Reuse, and Recycle
- These actions make a difference

4-What is deforestation?
5-Provide one cause and one effect of deforestation.
6-What is desertification?
7-Provide one cause and one effect of desertification.
8-What can humans do to protect the environment?
1. . . . Traditionally, [African] farmers cleared land, grew crops for a few harvests, then let the fields lie fallow for 10 or 15 years to rejuvenate as they moved on to clear more land, the study reports. But as they try to feed a rapidly growing population, the farmers instead grow crop after crop, sapping the soil’s fertility. “Nothing grows, so the topsoil is blown away by the wind and washed away by the rains,” said Amit H. Roy, president of the International Fertilizer Development Center, a nonprofit agricultural aid organization, which produced the study. “It goes into the river system, silting them, and out to the oceans.”. . .
