Aside from pollution is one of the scientist's greatest concerns. It is affected by the Greenhouse effect.
There are 4 stages in the Greenhouse effect.
1-Sunlight radiates from the sun, through space, to Earth's atmosphere.
2-The sunlight passes into the atmosphere and hits Earth. A modicum of it turns into heat energy in the form of infrared light. The heat gets soaked up by surrounding air and land, which in turn makes it warm.
3- Infrared rays, that are remitted into the atmosphere are caught by greenhouse gases.
4-The gas then consumes the light and is remitted back to the Earth's surface and warms it even better.
Some of the normally occurring greenhouse gases are methane and carbon dioxide. This is the way the Earth maintains itself warm enough for humans to survive on it. The exclusive problem with this is that humans improve the process even more.
Over the past 200 years, the emissions of greenhouse gases have been expanding due to the increase in technology that humans have created (example, factories). These human-induced gases contain carbon dioxide, methane, nitrous oxide, and ozone-depleting substances such as CFCs, also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are reproduced in several human activities such as fossil fuel combustion, waste disposal in trash yard, the use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous woodlands.
These human habits have already changed the chemical made up of the atmosphere. Between the pre-industrial times and today, we have seen the concentration of carbon dioxide rises 30% in some regions, in personal the northern hemisphere, human practices have increased engagements of aerosols in the atmosphere, which is a traditional form of air pollution), which produces to cool the atmosphere. With all these gases in the air, it is beginning to alter the Earth's climate. The temperature of the Earth's surface is as warm, if not warmer than it has been in any other century since at least 1400 AD. The temperature over the past century has risen one degree Fahrenheit over the last century. These last rare decades have been the warmest this century.
The sea level has risen 4 to 10 inches, and mountain glaciers worldwide have begun to withdraw. It is important to realize that with the current warming and the other climatic changes that have been getting on have not been related to one another. For example, warming has been tremendous over the mid-latitude continents in the winter and spring, with some areas of cooling, such as over the North Atlantic Ocean. Local and regional climate variations are not unpredictable with the existence of global warming. One current study by the IPCC (Intergovernmental Panel on Climate Change) said that unless governments do something to constrain the emissions of greenhouse gases to a lower level, global temperatures could rise 1.6 to 6.3 degrees Fahrenheit by the year 2100. This would illustrate the fastest rate of global warming since the end of the last ice age more than 10,000 years ago. With the heightened warming of the Earth, it could direct to catastrophic events that could compromise living things on our planet. One event is a major drought all around the world. With the warming of the planet, the water on the ground would rapidly evaporate causing the rivers and lakes to instantly dry up.
This would direct to crops dying from lack of rain, which would lead to food prices to skyrocket, which would lead to people dying from starvation if they do not have sufficient money to pay the food price. An additional event that would occur from global warming is the rough rise in sea level. As the Earth warms up, the polar ice caps will start to melt. This would put enormous amounts of water into Earths Oceans. All cities along the coast would be drenched from the rise in sea level. This would cause people to change positions to inland, and with more people inland, it would influence a shortage of space in some areas. With the coastal cities underwater, this would cause an outstanding economic strain on the rest of the cities throughout the world.
Global Warming would also cause shocking weather. Thunderstorms would be more strong than they have ever been. Tornadoes would be powerful than they normally would. With the warming of the surface, it would also warm the ocean over time. This would result in hurricanes to be various and stronger than they have ever been.
There is only one way to quit global warming before it becomes a real danger. That way is to stop emitting greenhouse gases that affect global warming. Only then will the problem of global warming be worked out.
