What is global warming <ul><li>Global warming is an increase In the earths average temperate. When the earth gets to hot the ice caps will melt we will die. </li></ul>
FAST facts <ul><li>Approximately 18,000 the Earth has began a gradual process of warming up after more than 100,000 years of ice age. Since the end of the last Ice age the Earths temperature has risen by 16 degrees F and sea levels have risen a total of 300 feet. The worlds natural wetlands produce more greenhouse gases contributions annually than all human sources combined . Over 95 percent of the Greenhouse Effect is the result of atmospheric water vapour in Earth's atmosphere. But because water droplets held in suspension clouds make almost as good a reflector as they do a thermal insulator, there is little rise in daytime temperatures due to the Greenhouse Effect. </li></ul><ul><li>Any greenhouse warming, if it does occur, is limited to primarily increasing night time temperatures, which provides beneficial moderation of night time low temperatures, but no increase in daytime high temperatures. Dr. Patrick Michaels, professor of environmental sciences, University of Virginia, has demonstrated this phenomenon very effectively. </li></ul>
Top actions I can take now! <ul><li>Replace a regular incandescent light bulb with a compact fluorescent light bulb (cfl) CFLs use 60% less energy than a regular bulb. This simple switch will save about 300 pounds of carbon dioxide a year. </li></ul><ul><li>Install a programmable thermostat Programmable thermostats will automatically lower the heat or air conditioning at night and raise them again in the morning. They can save you $100 a year on your energy bill. </li></ul>
Greenhouse effect <ul><ul><ul><ul><li>a great animated video on greenhouse effect </li></ul></ul></ul></ul><ul><ul><ul><ul><li>The greenhouse effect is the process in which the emission of infrared radiation by the atmosphere warms a planet's surface </li></ul></ul></ul></ul>
What is weather <ul><li>Weather Definition Weather is the day-to-day conditions of a particular place. </li></ul>
What is climate? <ul><li>What is Climate? Climate is often spoken about at the same time as weather, but it is something quite different. The climate is the common, average weather conditions at a particular place over a long period of time (for example, more than 30 years). We learn about different climates around the world. Deserts have a hot and dry climate while the Antarctic has a very cold and dry climate. </li></ul>
