Topic: Global Warming

• Heat is trapped by gases in the atmosphere.
• Gases are released quickly into the atmosphere causing the climate to change.
• 19 of the 20 hottest years since 1980, 30% more carbon dioxide in the air than 150 years ago.
• Carbon dioxide entering atmosphere faster than forests and oceans can absorb.
• Release of other gases adds to speed of climate change.
  

• Makes Earth warm enough for life to exist.
• Human activities (cutting down trees, driving cars, burning oil) cause a huge increase in greenhouse gases.
• Billions of tons of carbon dioxide in atmosphere from car exhausts, planes, factories.
• Trees and forests have been cut down.
• Other greenhouse gases being released from cattle and other farm animals. Also in soil.
  

• Ward Hunt Ice Shelf started to crack in 2000 and split in 2002.
• Ice disappearing from Arctic Ocean.
• Polar bears running out of food.
• Glaciers in Alaska are receding.
• 24 glaciers out of 150 left in Montana, icy coverings on mountains disappearing.

• Temperatures in northern regions are rising.
• Climate changes.
• Melting ice cuts off their food supply.
• Melting snow.
• Snow melting earlier in spring and falling later in the fall by a week or more.
  

• Ocean/sea levels rising by a half foot to 3 feet.
• People forced to move.
• Major flooding in coastal areas possible.
• Coral reefs dying along with animal life.
• Heavy rainstorms in some areas, droughts in others leading to forest fires.
  

• Temperatures rising, causing Greenland’s ice sheet to melt.
• Rising water will cover low lying lands.
• Risk of Antarctic ice cap melting, sea levels rise.
• Rising temperatures in the oceans.
• Rising temperatures add more heat and water vapor to the atmosphere and cause the soil to dry out where there are droughts.

• Cold places becoming warmer.
• Checkerspot butterfly disappeared from Mexico.
• Species may become extinct.

• Ice melting sooner, fewer cold days.
• Animals migrating to colder places to survive.
• Crowding into colder places and travel.

• Not much we can do.
• People trying to use less energy, using wind/solar power, reduce release of gases, protect wildlife.
• People are walking, biking or using public transportation, using reusable bags, taking shorter showers, planting trees.
• People using fans, energy saving light bulbs, turning off electrical appliances, installing doubled paned windows and solar panels on their house.

• Planet may be going through a warming cycle.
• Nations are trying to slow down climate change.
• Nations and governments are trying to help use less energy.
• Families are trying to slow down climate change.
