This document discusses global warming, including its causes, effects, and projections. It begins by defining global warming and the greenhouse effect. It then outlines both natural causes like methane release and man-made causes such as burning fossil fuels. Effects already observed include rising sea levels and impacts on plants and animals. Future predictions include increased temperatures, sea level rise, and species extinction. The document concludes by suggesting precautions like using more efficient vehicles and planting trees to help prevent further global warming.

13. Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F).

18. Effects of global warming already being felt on plants and animals worldwide

19. Global Warming Effects that will happen in the future:EFFECTS OF GLOBAL WARMING

21. Global warming will affect agriculture. New crops will be able to be grown in areas that are currently too cold to support them. However, more pests and diseases may offset any benefits higher temperatures may have. Water resources will also be affected. Effects of Global Warming on Earth in Future

24. According to the National Climactic Data Centre estimates, $100 billion of damage was caused by hurricanes hitting the U.S. coast in 2005 alone.

25. It is also projected that 15-37% of all plant and animal species could be wiped out by global warming by the year 2050, which could further cause considerable damage to our planet's ecosystem.GLOBAL WARMING STATISTICS

26. Projection of global warming Calculations of global warming prepared in or before 2001 from a range of climate models under the SRES A2 emissions scenario, which assumes no action is taken to reduce emissions and regionally divided economic development. The geographic distribution of surface warming during the 21st century calculated by the HadCM3 climate model if a business as usual scenario is assumed for economic growth and greenhouse gas emissions. In this figure, the globally averaged warming corresponds to 3.0 °C (5.4 °F).

28. The Northern Hemisphere cover should decrease further, but the Antarctic ice sheet should increase.

29. The sea level should rise by between 9 and 88 cm (3.5" to 35").

30. Other changes should occur, including an increase in some extreme weather events.

31. The United States is ranked nr.1 among large nations of being a global warming polluter
