Global Climate Change

  1. 1. Global Climate Change and the earth’s Biomes<br />By Shannon Storey<br />
  2. 2. What is a biome?<br />A biome is a large geographical area that is inhabited by particular plant and animal groups.<br />The climate and terrain of a region determine which biomes are able to exist there.<br />Major biomes include deserts, tundra, grasslands, forests, and various aquatic environments.<br />
  3. 3.
  4. 4. Tundra<br />The tundra occupies earth’s northern hemisphere.<br />Soil is poor in nutrients and permafrost allows for little room for deep rooting plants and trees.<br />It is the coldest of all biomes.<br />
  5. 5. Desert<br />Deserts cover nearly 1/5 of our planet.<br />They receive very little rain.<br />Vegetation consist of plants that have evolved to retain water.<br />Most animal species are nocturnal to cope with the unbearable heat during the day.<br />
  6. 6. Forest<br />Forests represent 1/3 of the earth’s land.<br />They are found all over the world. <br />They are characteristic for their vast variety of trees.<br />Rainforests are a wet climate area. They are known for their numerous plant and animal species.<br />
  7. 7. Grasslands<br />Grass is the dominant plant life here.<br />Serve as grazing areas for many animals and are commonly used as farmland for humans.<br />
  8. 8. Aquatic<br />Water covers approximately 75% of our planet.<br />There are two types of aquatic biomes: marine and freshwater.<br />The marine region consists of oceans, coral reefs, and estuaries.<br />The freshwater region exists in lakes, ponds, swamps, etc.<br />
  9. 9. Which biome is most impacted by global climate change?<br />All of them!<br />Some scientists argue that the rainforest biome is the most at risk due to species being less accustomed to fluctuations in temperature and precipitation.<br />The tundra and desert biomes are also threatened and may no longer be capable of supporting the same vegetation they do now in the years to come.<br />Our oceans are also taking a toll due to global climate change. Oceanic circulation, coastal erosion, sea-level rise, and changes in species distribution and migratory routes are just a few of the issues being studied and documented today.<br />
