BACKGROUNDWhat is altitude change?The appellation "climate change" refers to a change in the abiding boilerplate of a region's acclimate events. Altitude change is natural, and Earth's altitude has afflicted abounding times in its history. Concern about the accepted altitude change, however, is due to the actuality that Earth's boilerplate apparent temperature has risen added than 1 bulk Fahrenheit over the aftermost 100 years. Such a accelerated bulk of change is aberrant in the aftermost 1,300 years. Carbon dioxide, methane and added gases, accepted as "greenhouse gases," blot calefaction and allurement it in our atmosphere. Beastly activities, including the afire of deposit fuels and the use of articles such as chlorofluorocarbons, frequently accepted as CFCs, access the absorption of greenhouse gases in the atmosphere. The Intergovernmental Panel on Altitude Change states in their Altitude Change 2007 Synthesis Address that "there is actual aerial aplomb that the all-around boilerplate net aftereffect of beastly activities back 1750 has been one of warming."
How does altitude change affect the Chill and its wildlife?An added boilerplate temperature in the Chill has affecting results. Glaciers become thinner and retreat at a accelerated pace. There is a abridgement in sea ice awning and thickness. Patterns of condensate and blast shift. All of these changes affect wildlife by abolition clearing patterns, introducing antagonism from added breed overextension northward, and impacting the availability and accessibility of food.
What can we do?We all accept the adeptness to abate the bulk of action we use and accordingly abate the bulk of deposit fuels burned. Here are some ideas:

PRE-VIEWING ACTIVITIES
KWL ChartUse a KWL Chart with your acceptance to appraise what they apperceive about altitude change, how it affects the Chill and how it may affect animals in the Arctic.
Sea Ice ChangeUse these images from the National Snow and Ice Data Centermost to appraise with your acceptance how the bulk of Chill ice varies from year to year.
What do your acceptance apprehension about the admeasurement of the sea ice in the accomplished few years?

Go In-DepthAre there questions your acceptance still accept about all-around abating or Chill animals? After creating a account of questions, accept the acceptance accept one of the questions or an beastly from the video to analysis further. They again address their allegation to the class.
Visit a Zoo, an Aquarium or a Attributes CenterVisit a zoo, an aquarium or a attributes centermost to apprentice about the impacts of altitude change on added ecosystems and animals. Are the issues added bacilli face agnate to those faced by animals in the Arctic?
Create an Advisory Banana StripHave acceptance accept one beastly discussed in the Ocean Adventures video to affection in an advisory banana strip. They can architecture a five- to eight-cell banana band assuming the threats the beastly faces due to all-around warming. The aftermost corpuscle of the band should active readers to an action they can booty to advice abstain the book presented.
Taking It HomeAs a class, begin means in which individuals and families could abate action consumption. Again accept anniversary apprentice accomplish a account of energy-saving strategies to column on his or her refrigerator at home. After implementing the account for a month, acceptance can ask their parents to attending at their abutting action bill to see if the family's action burning has decreased.
