  2. 2. What is WEATHER? <ul><li>the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc. a strong wind or storm or strong winds and storms collectively </li></ul>
  3. 3. What is CLIMATE? <ul><li>the composite or generally prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunshine, cloudiness, and winds, throughout the year, averaged over a series of years </li></ul>
  4. 4. What is GLOBAL WARMING? <ul><li>Glaciers are melting, sea levels are rising, cloud forests are drying, and wildlife is scrambling to keep pace. It's becoming clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than in the last 650,000 years. </li></ul>
  5. 5. What are the similarities between weather and climate? <ul><li>Weather is the day-to-day state of the atmosphere, and its short-term (minutes to weeks) variation. </li></ul><ul><li>Climate is defined as statistical weather information that describes the variation of weather at a given place for a specified interval. </li></ul>
  6. 6. How has the change in climate created a change in weather patterns? <ul><li>The colder the ground is the more it snows. </li></ul><ul><li>The more heat, more humidity. </li></ul>
  7. 7. How is the global climate changing?  Is it getting warmer or colder?  How do we know? <ul><li>Its getting hotter. </li></ul><ul><li>Glaciers are melting, animals migrating, temprtures rising. </li></ul>
  8. 8. RAIN FOREST <ul><li>The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. </li></ul><ul><li>Rainforests now cover less than 6% of Earth's land surface. </li></ul>
