An Introduction to Global Warmingfor Students in Grades 6-8

Global WarmingThis term refers to the general increase in the earth’s average temperature caused by the presence of greenhouse gases in the atmosphere,which causes changes in climate patterns across the globe.Some of the news you may have heardPolar bears are losingtheir habitatsSea level is risingHurricanes are gettingbigger and strongerGlaciers are melting fastTemperatures are going upHow do we know?Scientists have been able to study climate change by lookingat tree cores, atmospheric composition, sediment cores, icecores and through observation.

ResourcesMany resources are available for more information on climatechange and global warming. Here are a few:FOR STUDENTSFOR TEACHERS AND PARENTSOn the Web:Union of Concerned Scientistswww.climatechoices.orgEnvironmental Protection Agency, Oceanic and Atmospheric Administration(NOAA)For grades 6 - ature e/calculatorNature Conservancy’s SupportingEnvironmental offers links to otherclimate change warming/climate home.htmlNature eNational Wildlife Federation’s Climate Global Art’s Guide to Planet Earth,Art Sussman, Ph.D.An Inconvenient Truth: The Crisis of GlobalWarming.

Key Conceptsclimate change—a term used to describe trends in the earth’s climate.For example, scientists see that the planet’s average temperature isrising. This affects wind and ocean currents as well as yearly amounts ofrain and snow. Climate change affects different parts of the world indifferent ways. Take a look at what is happening in the Arctic ascompared to the Hudson warming—refers to the general increase in the earth’saverage temperature, which causes changes in climate patterns acrossthe globe. The earth’s average temperature has been increasing over thelast century. For example, there is some evidence that suggests that theU.S. Northeast will gett colder as the poles melt and cold, fresh waterchanges currents near the East Coast.greenhouse gases—are carbon dioxide and methane, mostly causedby human activity. Greenhouse gases are in the atmosphere, absorbingand holding heat, which causes earth’s temperature to rise.Keywords to explore and know: acidification, alternative energy,atmosphere, biomass, carbon cycle, carbon dioxide, carbon footprint, conservation, deforestation, ecosystems, energy, estuary, food web, fossil fuels,fuel efficiency, greenhouse effect, habitat, Industrial Revolution, invasiveand native species, natural resources, ozone, photosynthesis, pollution,renewable and solar energy, species migration, symbiosis, watershed.Look up key events in American environmental history—for example,Earth Day, an environmental movement that was founded in 1970when 20 million Americans protested for a healthy and sustainableenvironment. Earth Day represents the hope for a clean planet.Other examples are the Clean Air Act, Clean Water Act, EndangeredSpecies Act, Kyoto Protocol and the SCENIC HUDSON DECISION.

Carbon FootprintSince the Industrial Revolution (from about1850 to the present) astounding amounts ofgreenhouse gases have been introduced intothe earth’s atmosphere. This is primarily due toincreased use of fossil fuels for generating power.Americans are huge consumers of products thatuse enormous amounts of energy and generatelarge amounts of waste.A carbon footprint is the amount of carbondioxide a person, family or business emits throughthe use of fossil fuels.Your carbon footprint is the impact your lifestylechoices have on the earth. Two of the biggestcontributors are your driving and travel habits aswell as your electricity use at home. Other impactscome from your diet and the products you buy.Have you stopped to consider yourpersonal contribution to climate change?You send greenhouse gases into the atmospherewhen you. watch TV play video games turn on a light ride in a car put trash in a landfill use electricity to listen to music

Impacts on the Hudson ValleyAs temperatures increase around the world, weather patternsand seasons will change here in the valley. These changes inclimate already are having troubling effects: higher temperatures more intense rainand floods less snow increased droughts increased cost of food poor air quality changes in forestsand wetlandsJosh Clague (map & Black Creek photo) sea-level rises(remember, theHudson River isconnected to theAtlantic Ocean)Does this affect you?Use the resourcesprovided in this bookletto further investigate.Hudson River Watershed Map*Information from the Hudson River Estuary Program at: and the Union ofConcerned Scientists:

Aspect 1: Global warming itself . Global Warming . is, itself, the product of many factors, and its relevance to anything else depends on its . magnitude. Emissions of minor greenhouse gases is a factor, but only one factor (and probably not the most important) among several. What are other factors?

A. Global warming refers to an increase in average global temperatures, which in turn causes climate change. Climate change refers to changes in seasonal temperature, precipitation, wind, and humidity for a given area. Climate change can involve cooling or warming. Temperature readings taken around the world in recent decades, and scientific studies of tree rings, corals, and ice cores, show .

Global warming is when Earth’s air and the water get warmer. Global warming is one part of climate change. This does not sound good!

A.1 5Human activities are estimated to have caused approximately 1.0 C of global warming above pre-industrial levels, with a likely range of 0.8 C to 1.2 C. Global warming is likely to reach 1.5 C between 2030 and 2052 if it continues to increase at the current rate. (high confidence) (Figure SPM.1) {1.2}
