Climate change power point

  1. 1.  Scientistshave warned that the worlds climate has changed a lot, and has affected many living and non-living things. Many places that were warmer are now getting colder, and many colder regions are getting much more colder or even warmer this is know as Global Warming.
  2. 2.  The Earths climate is changing in ways that you cant easily see. The Earth is getting warmer because people are adding heat-trapping gases to the atmosphere, mainly by burning fossil fuels. These gases are called greenhouse gases. Warmer temperatures are causing other changes around the world, such as melting glaciers and stronger storms.
  3. 3.  These changes are happening because the Earths air, water, and land are all linked to the climate. The Earths climate has changed before, but this time is different. People are causing these changes, which are bigger and happening faster than any climate changes that modern society has ever seen before.
  4. 4.  Climate The total of all weather occurring over a period of years in a given place. It is the average weather condition of that place. Climate tells us what it’s usually like in the place where you live. Weather is what is happening outdoors in a place at a given time. It can change a lot within a very short time. For example, It can be windy at night, and sunny in the morning.
  5. 5.  Greenhouse effect In a way, the earth is like a glasshouse. The earth has some very important gasses in the atmosphere that keeps us warm. Some of these gases are water vapour, carbon dioxide, nitrous oxide and methane. When the sun heats the earth, these gases keep the heat on the earths surface. Without these gases, heat would escape back into space and Earth’s average temperature would be about 60°F colder.
