Teacher Background, Since the Industrial Revolution there has been a significant increase in the amount of carbon dioxide and. other greenhouse gases in the atmosphere As a result more of the solar radiation reaching the surface of the. Earth is absorbed causing a significant increase in the average temperature worldwide see graphic below. Scientists have predicted that the average temperature of the Earth will increase by at least 3 6 F While. this does not seem like a large change it is very significant The last ice age was caused by a decrease in. average temperatures of less than 2 F The predicted increase in average temperature has severe. consequences including rising sea levels more intense hurricanes increased disease increased extinctions. and food shortages,Teacher Tips,It may be helpful to use an electronic. classroom polling system to conduct the,interest inventory if this technology is. available A Last Warning on Global,Warming Is Global Warming Drowning. Africa and Global Warming is Hot Stuff,are articles that discuss many effects of.
climate change It is up to teachers to,choose the article that best meets the needs. of their classroom Climate Change and,Global Warming are both terms that refer. to the increase of the average temperature,on Earth While there are differences. between these two terms they are used,interchangeably throughout this lesson. http science howstuffworks com global warming2 htm. 1 Start by having students take the Climate Change pre quiz 5 minutes For advanced students you may want. to add additional questions,2 Poll the class to tabulate student answers.
3 Explain to students that they will find the answers by reading articles on the effects of climate change. 4 Read either A Last Warning on Global Warming reading level of 10 7 or Is Global Warming Drowning. Africa reading level of 12 0 as a class, 5 Have students list the causes and effects of climate change. 6 Each group will look at one effect in more detail by reading an article and answering questions and filling in a. graphic organizer Hand these out to each group, 7 After answering the questions have each group fill in the graphic organizer and enlarge it on the butcher. 1 Each group will present their graphic organizer to the class While other groups are presenting students. should be copying down the graphic organizers, 2 After the presentations students should work in their groups to construct an overall concept map for the causes. and effects of climate change, Closure Have students take the Climate Change post quiz. Global Warming Lesson Air The Search for One Clean Breath Page 2. Ventura County Air Pollution Control District Ventura CA. Assessment Climate Change post quiz graphic organizers. Extensions This could be developed into a full research paper where students further investigate the. effects of climate change and how to combat them,Homework None.

Allergies Getting Worse Blame Global Warming, One of the few potentially positive effects of climate. change at least in the short term is that increased concen. trations of carbon dioxide in the atmosphere may enhance. the growth of plants That could be good for agriculture. though warming temperatures and changing rain patterns in a. warmer world might wipe out that advantage But there are. no unalloyed gifts from climate change Recent research suggests that global warming. will also exacerbate respiratory allergies as higher CO2 concentrations lead to vast. increases in ragweed pollen production There s no denying there s a change says. Paul Ratner an immunologist with the American College of Allergies It s definitely. bad news for people who have allergies, Asthma and other respiratory ailments are already on the rise in much of the world.
The World Health Organization estimates that 300 million people globally have asthma. with 250 000 dying from the disease each year That rate is up considerably over the. past few decades and scientists say a number of factors could be at work One clear. reason is rising levels of ragweed pollen which can be connected directly to rising. levels of CO2 Researchers have shown repeatedly that elevated levels of CO2 stimu. late weeds to produce pollen out of proportion with their growth rates meaning you. get more pollen per plant which means more allergies Even worse it seems that the. weediest species seem to thrive disproportionately in high CO2 environments The. wave of urbanization in America and much of the world doesn t help the urban envi. ronment often hotter and with more CO2than rural areas is ragweed heaven Urban. places because of the baking effect of that increased concrete definitely pollinate. more says Ratner It doesn t help that warming will also increase the production of. ground level ozone a respiratory irritant that worsens asthma. Longer growing seasons in a warmer world may further worsen allergies A study in. September s Journal of Allergy and Clinical Immunology reported data from 1982 to. 2001 showing that for example increasingly early pollination of the European olive in. Spain led to higher overall pollen counts similar to what is found in warmer parts of. the Mediterranean comparable outcomes can be expected in other temperate parts of. the world as climate change kicks in A similar effect will also be felt in the northward. shift of what is known as the hardiness zones meaning that northern countries. where allergies were once rare may no longer be as safe Those borderline northern. regions will definitely feel changes says Ratner, Global Warming Lesson Air The Search for One Clean Breath Page 6. Ventura County Air Pollution Control District Ventura CA. The causes of allergies and respiratory disorders are complex and scientists cannot. predict exactly how much impact climate change will have on their global rates But. the recent data records on pollen counts rarely go back more than 20 years. certainly would indicate that warming will only make things worse So what can be. done to help millions of sneezing watery eyed patients As allergy sufferers already. know not a whole lot But any action taken to control rising CO2 levels might at least. help stem the increase in global allergy rates So far the global asthma epidemic. shows no signs of abating and in a warmer world effective treatments for allergies. will likely become even more important One option for allergy suffers might be to. start agitating for action to reduce CO2 emissions after all the only thing you have. to lose is your breath, Source Time Magazine Bryan Walsh September 15 2008. http www time com time health article 0 8599 1841125 00 html.

How Climate Change Will Impact Animals, The threats to wildlife on the African island of Madagascar. are manifold rampant deforestation that has stripped most of. the island of its original forest cover leaving a wasteland a. human population that is growing at 3 a year straining. natural resources and hunting animals for food especially. Madagascar s emblematic lemurs extractive industry includ. ing a nickel mine not far from a national park that could. become the world s biggest, There s another danger that s invisible but may be more dangerous than the others put. together climate change Global warming will do to wildlife what it may do to humans. As the climate changes animals may be forced to move out of the habitats they re ac. customed to like human refugees Global warming is something that all conservation. ists are worried about says Russell Mittermeier the president of Conservation Inter.
