Antarctica is located in the Southern Hemisphere. The continent overlies the South Pole and covers 13,824,000 square kilometres.
(Level: student and teacher) http://www.glacier.rice.edu/invitation/1_ice.html
Ice covers 98% of Antarctica. The continent is home to 70% of the Earth's fresh water and 91% of its ice. The ice averages 2.3 kilometres in thickness. The thickest ice is about 4.8 kilometres thick.

Antarctica today. Despite its isolation, Antarctica is not immune to global pollution, which can be measured in the younger ice layers. Air bubbles trapped in the ice reveal an increase of atmospheric CO2 starting in the Industrial Revolution and accelerating from the mid-twentieth century onwards.
(Level: teacher) Greenhouse effect http://www.eecs.umich.edu/~coalitn/sciedoutreach/funexperiments/agesubject/lessons/greenhse.html
What is a greenhouse? What is the 'greenhouse effect'? A greenhouse is a building that keeps plants warm so that they can grow.

How greenhouse gases work. The Earth is warmed by the Sun and expels excess heat into space. Greenhouse gases at high altitudes retain excess heat in the Earth's atmosphere. When the amount of these greenhouse gases increases, the temperature of the Earth rises.

The greenhouse effect has been described as potentially the most dangerous environmental problem facing mankind, with consequences second only to nuclear war.
(Level: student and teacher) Global warming http://ccwf.cc.utexas.edu/~bogler/ecology/atmosphere.html
Major pollutants: CO (carbon monoxide), CO2 (carbon dioxide), SO2 (sulphur dioxide), NOx (nitrogen oxides), CH4 (methane), and volatile hydrocarbons.
Known sources of each. Industrial smog caused by particulates and SO2.

What is the greenhouse effect? The phrase describes the increased warming of the Earth's surface and atmosphere as a result of the increasing levels of greenhouse gases which let energy in but prevent some of it from going back out.

Energy and science projects for schools: recreating the greenhouse effect.
(Level: student) Ozone layer http://www.newcastle.infohunt.nsw.gov.au/council/belair/oxy.htm
The ozone layer is a region of the atmosphere from 19 to 48 km above the Earth's surface. Ozone concentrations of as much as 10 parts per million occur in the ozone layer. The ozone is formed by the action of sunlight on oxygen.
