It's a fact that the weather is getting decidedly warmer. In some places in the United States, the average rise in temperature is around four degrees Fahrenheit. However, all the states show some degree of warming. Global warming has upped the level of drought. A major drought in the US lasted from 1999-2002. There were only two other droughts in the last forty years that were so widespread and devastating. Crops were damaged or would not grow at all, thus shortening the food supply. While the overall effect of global warming is heat followed by drought, there are still storms. Since global warming energizes the atmosphere, these storms will be different. When all is going well, a gentle rain will soak into the earth gradually, causing no more than a minor inconvenience to people. Global warming is responsible for many climate changes. Often, people cause the increase in global warming that precipitates these changes. If people could make it a common goal to cut down on activities that promote global warming, the earth would be a much more stable environment. Complexity in Predicting Global Warming Some of the difficulties inherent in forecasting future global warming have to do with those same factors that every meteorologist faces. Winds can cool the air or warm it depending on the direction they take. Cloud cover can cool a hot day. Air masses move in to cause storms as cool fronts and warm fronts are generated. It is hard to predict the future of global warming when little is known about the actions people will take to prevent it, or not. Underdeveloped countries will strive towards development. Generally in the past this has meant using the cheapest industrial equipment available, even if it is the most polluting. However, these countries may decide to put emphasis on preventing global warming instead. It is not known at this time how fast the population of the world will grow. Statisticians can make educated guesses, but a number of factors can always change the dynamics of population growth. Biological factors, as well as governmental policies and economics can all play a part. The more people on earth, the greater the chance for global warming. The proliferation of dark areas can lead to global warming. The trouble with using this fact to predict global warming is that it is not known how many dark areas will be uncovered by melting ice. As long as there is enough ice to maintain a light color, a good deal of the heat will be reflected off into the atmosphere. How to Minimise Global Warming One way to cut the greenhouse emissions of houses, and therefore help stop global warming, is to minimize the energy use needed to sustain comfortable living in a house. Heating and cooling have a big effect on the amount of global warming caused by a house. Some ways to help this are very simple. One is to design the house to sit on the lot so that sunlight will come in through the windows and warm the house. It can also be oriented so that breezes will blow through the windows more naturally for cooling. Passive solar energy can be used to heat and cool the house. This will cut down on the greenhouse emissions from a house. Global warming will be lessened. Insulation is important to maximize on the cool or heat that is in the house. With good insulation, you will need a less intense heat or cooling source. The state of Washington has required builders of buildings larger than 5000 square feet to use green building practices. Their law was enacted in 2005. It should help to keep a cap on global warming. Health Concerns Related to Global Warming The increase of global warming brings increase in mosquitoes. The mosquitoes carry malaria to new regions like Indonesia because of global warming. And dengue fever has reached elevations in the Andean Mountains of Colombia where it was never seen before. Often, people take dangerous risks during floods. They drive into water, thinking that they can make it across. When they do not, they can get swept away and drowned. There is no graver consequence of global warming than death, of course. If all people knew how much global warming can affect their health, they might be more prone to working on a solution.
