GLOBAL WARMING

The phenomena (global warming) is so called because of the gradual warming up of the earth’s atmosphere and the possibility of associated changes in the global weather patterns as a result of emissions into the atmosphere of greenhouse gases (carbon dioxide, carbon monoxide, nitrous oxide and methane). 1
The emission of greenhouse gases (GHGs) is the result of production and consumption activities of those nations which burn fossil fuels like coal, oil, and gas to generate electricity; this is also referred to as the greenhouse effect (The greenhouse effect is when the temperature rising because the sun’s heat and light is trapped in the earth’s atmosphere, but it can’t get out).
Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot(the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat). However, this is just one advantage in a list of countless disadvantages.
“Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. (a problem for many of the plants animals and people on the Island). The ocean are affected by global warming in other ways. Warm water is harming and killing algae (a source of food for sea animals) in the ocean.
Global warming is also destroying many huge forests. The pollution that causes global warming is linked to acid rain which gradually destroys almost everything it touches. Global warming is also causing many more fires that wipe out forests. This happens because some plant leaves can be so dry that they catch on fire.” 2
“ Africa is the continent that will be hit hardest by climate change. Unpredictable rains, floods, prolonged droughts, and rapid desertification, among other signs of global warming, have in fact already begun to change the face of Africa.3
Other impacts from increasing temperatures are already happening; Ice is melting worldwide, especially at the Earth’s poles. Sea level rise became faster over the last century; Precipitation (rain and snowfall) has increased across the globe, on average.
Other effects could happen later this century, if warming continues. Sea levels are expected to rise by the end of the century, and continued melting at the poles could add between 4 and 8 inches. Hurricanes are likely to become stronger. Species that depend on one another may become out of sync. Floods and droughts will become more common. Less fresh water will be available. Some diseases will spread such as malaria carried by mosquitoes. Ecosystems will change; others won’t be able to move and could become extinct.4
We can combat global warming by voicing the need for laws that will steer our nation toward important solutions to global warming, choosing an efficient vehicle that is least polluting, Drive less-walk where possible, replace your light bulbs with compact fluorescent bulbs. Choose renewable energy e.g. wind and solar.5
Global warming is too serious for the world any longer to ignore its danger or split into opposing factions on it, says Tony Blair. Global warming is indeed a scam, perpetrated by scientists with vested interests, but in need of crash courses in geology, logic and the philosophy of science.6
