DAY 1
Section 13.1 Climate & Climate Change
Objectives
1. Explain the difference between weather and climate.
2. Identify four factors that determine climate.
3. Explain why different parts of the earth have different climates.
4. Explain what causes the seasons.
13.1 Vocabulary
climate - the average weather conditions in an area over a long period of time
latitude - the distance north or south from the equator; expressed in degrees
El Nino - the warm phase of the El Niño–Southern Oscillation; a periodic occurrence in the eastern Pacific Ocean in which the surfacewater temperature becomes unusually warm
La Nina - the cool phase of the El Niño–Southern Oscillation; a periodic occurrence in the eastern Pacific Ocean in which the surfacewater temperature becomes unusually cool
Brightstorm: Climate Change (3:12)
Climate change is defined as the long term change in weather patterns over time. The greenhouse effect is the trapping of heat in the Earth by gasses like carbon dioxide and some scientists argue that increases in atmospheric greenhouse gases will trap more heat. When more heat is trapped, there is more energy to drive weather patterns. This increased heat can also have unpredictable effects such as the melting of ice caps, shifting rainfall patterns and more powerful storms.

A History of Earth's Climate by scishow (11:20) Published on May 27, 2013
Earth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we're gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we're experiencing now is different than anything this planet has encountered before. So, let's take a stroll down Climate History Lane and see if we can find some answers to a question that's been bugging Hank a lot lately - just how much hot water are we in?
DAY 2
Section 13.2 The Ozone Shield
Objectives
1. Explain how the ozone layer shields the Earth from much of the sun’s harmful radiation.
2. Explain how chlorofluorocarbons damage the ozone layer.
3. Explain the process by which the ozone hole forms.
4. Describe the damaging effects of ultraviolet radiation.
5. Explain why the threat to the ozone layer is still continuing today.
13.2 Vocabulary
ozone layer - the layer of the atmosphere at an altitude of 15 to 40 km in which ozone absorbs ultraviolet solar radiation
chloroflourocarbons (CFC’s) - hydrocarbons in which some or all of the hydrogen atoms are replaced by chlorine and fluorine; used in coolants for refrigerators and air conditioners and in cleaning solvents; their use is restricted because they destroy ozone molecules in the stratosphere (abbreviation, CFCs)
ozone hole - a thinning of stratospheric ozone that occurs over the poles during the spring
polar stratospheric clouds - a cloud that forms at altitudes of about 21,000 m during the Arctic and Antarctic winter or early spring, when air temperatures drop below –80°C

DAY 3
Section 13.3 Global Warming
Objectives
1. Explain why Earth’s atmosphere is like the glass in a greenhouse.
2. Explain why carbon dioxide in the atmosphere appears to be increasing.
3. Explain why many scientists think that the Earth’s climate may be becoming increasingly warmer.
4. Describe what a warmer Earth might be like.
13.3 Vocabulary
greenhouse gases - a gas composed of molecules that absorb and radiate infrared radiation from the sun
global warming - a gradual increase in the average global temperature that is due to a higher concentration of gases such as carbon dioxide in the atmosphere
Kyoto protocol - an international treaty according to which developed countries that signed the treaty agree to reduce their emissions of carbon dioxide and other gases that may contribute to global warming by 2012
