Through the eyes of most scientists, global warming is seen as a very serious and severe threat. The actions taken by humans, such as industry and consumption of fossil fuels plus the increase in population and agriculture have played a big part in global warming. If something is not done soon the results could be very bad.

By the middle of the twenty first century, there is evidence that the Earth will be warmer than it has been at any time in human history, and quite possibly since the end of the dinosaurs, some 65 billion years ago. If we stay at the rate we our now (fossil fuel consumption / growth in population) then within the next two century the Earth's air might not be fit to breath. Many people in the world do not think …show more content…

Water vapor is believed to increase surface warming because its concentrations depend on the heat generated by other greenhouse gases. All of these gases are being emitted to the atmosphere at alarming rates because the human population, scale of energy use, industrial activity, and agriculture are growing drastically.

Greenhouse gases come from such mainstays of modern life as electrical power plants, automobiles, and heavy industry. Growing consumption of fuel by less efficient cars and light trucks suggests that motor vehicles may soon overtake industry as the largest source of gases suspected of causing global warming by effectively creating a greenhouse around the Earth. Many people do not want to decrease their standard of living by reducing their consumption of fossil fuels. These people do not realize that if they reduce their consumption, there will be a reduction in the amount of greenhouse gases. If this does not happen and global warming continues, the long-term effects may be catastrophic.

One of the most serious effects of global warming, as it continues to intensify, is the increase in the ocean levels. Thermal expansion of the ocean and glacial melting are likely to cause a .5 to 1.5 meter rise in the ocean level by the year 2100. As the ocean level rises and if no protection is provided, many freshwater supplies could be jeopardized. Tens and possibly hundreds of millions of
