Global Warming and Climate Change - by Andrada Clipici

  1. 1.  - The most pressing problems humankind faces today include : global warming, climate change, energy conservation, pollution, deforestation and, certainly not the last, freshwater resources.
  2. 2. Global warming was very likely caused by increasing concentrations of greenhouse effect resulting from human activity. With global warming on the increase chances for ecosystems to adapt naturally are diminishing. Pollution can cause instability or discomfort to the ecosystem.
  3. 3. The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 0.8 degrees Celsius, and even more in sensitive polar regions.  Some impacts from increasing temperatures are already happening.  Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. 
  4. 4.  Air pollution is due to human influences that contaminate the air with chemicals. The two types of air pollution: smog and soot pose health risks and environmental dangers. Of the two forms of air pollution, particle pollution is more dangerous.  The removal of trees from the ecosystem without sufficient reforestation has resulted in damage to habitat and biodiversity.
  5. 5. The highest percentage of electricity consumed by mankind is produced by burning fossil fuels. This results in the emission of CO2 that is released to the atmosphere. It also contributes to enhancing the greenhouse effect and global warming. However, power plants are emitting sulfur dioxide, nitrogen dioxide and carbon.
  6. 6. The consequences of the greenhouse effect and global warming are: - increasing water levels and ocean temperatures - higher frequency of hurricanes, tornadoes and storms - and the most important: the animals who are in danger because their territories are being destroyed by people.
  7. 7.  Rising sea levels will result in migration of millions of people and inundating productive farmland. Melting glaciers will reduce water flow to some of the most densely populated regions of the world, affecting agricultural production and national income. No doubt, global warming affects the environment, as well as humans and other creatures.
  8. 8. In conclusion, some of the major effects of global warming are: 1. Acid rain Gases mix with moisture in the air and precipitation are acidic, making them similar to lemonade. Acid rain destroys plants and animals. 2. Ecosystems will change. Some species will move further north or become more successful; others won’t be able to move and could become extinct.
  9. 9. 3. Forest fires Global warming is not only able to melt the glaciers, but can cause devastating fires. 4. Gene changes The spring which comes early creates a huge problem for animals.
