Greenhouse effect is the process on the earth planet caused by the gases trapping heat and energy from the various sources. Such gases are called as green house gas like CO2, methane, nitrogen oxide, CFCs, ozone, etc trap heat and warm the earth surface. Such gases hold the heat in the earth atmosphere and cause many changes in the climate and weather. Global warming causes increase in heat waves, floods, droughts, increase in sea level, melting glaciers, endangering many animals and plants species, and negatively affected the way of living of human beings.
Fundamental changes in seawater chemistry are occurring throughout the world’s oceans. Since the beginning of the industrial revolution, the release of carbon dioxide from humankind’s industrial and agricultural activities has increased the amount of carbon dioxide in the atmosphere. The ocean absorbs about a quarter of the carbon dioxide we release into the atmosphere every year, so as atmospheric carbon dioxide levels increase, so do the levels in the ocean. Initially, many scientists focused on the benefits of the ocean removing this greenhouse gas from the atmosphere. however, decades of ocean observations now show that there is also a downside the carbon dioxide absorbed by the ocean is changing the chemistry of the seawater, a process called ocean acidification.
The Environmental Media Services Organization has found that the greenhouse effect could drive temperatures up as much as 6 degrees by the year 2100 – an increase in heat comparable to the 10-degree warming that ended the last ice age (Fast Facts). If a 10-degree warming was the factor that ended the last ice age, imagine what another warming could do. Consider hydrology, for instance. Warm air holds more water vapor than cold air, so there is an increase in evaporation in dry areas, and hence more drought – something that has been documented on every continent. Once that water is in the atmosphere, it’s going to come down somewhere – and, indeed, we have seen the most dramatic flooding ever recorded in recent years. In 2004, 300 million humans, 1 in 20 of us, had to leave their homes for a week, a month, a year, or forever because of rising waters (The Planet Speaks 124). Much of the gained water would be from melting icecaps in the ocean and melting glaciers on land. Coastal cities and islands could be wiped out.
There are many negative environmental effects of global warming. Another effect is the fact that higher temperatures will lead to a change in the water cycle. Warmer temperatures will cause a greater amount of evaporation from lakes, rivers, streams, and oceans. In some areas this could be good, but in other areas it could be bad. In northern regions of the U.S., where we live, an increase in the temperature and the amount of rain could extend the growing season of crops. In turn, the farmers could make more money. It could also hurt some farmers though. There is a possibility that crops could get too much rain and crops could be killed. Certain areas would get less rain, which would lead to more droughts. Warm temperatures and wet weather would be the main result of global warming in certain areas, and warm temperatures and wet weather are factors that promote tropical storms. Thus, tropical storms would appear more often and with greater frequencies.
More rain as a result of global warming will also force plant life and its species to adjust their location. Species migrate naturally, but scientists say that global warming would cause them to migrate at a much faster rate. If the climate changes, some forest species in North America will shift by as much as 300 miles to the north (Campaign to Stop Global Warming). Plants will also be forced to migrate. If one region is getting more rain than another, plants that need more rain that are on the border of these two regions will naturally begin migrating into the region that is getting more rain.
Global warming has become a major environmental problem in the last five years and is not improving. The small increases in temperature seem harmless, but they can do an enormous of damage to the earth’s ecosystem. Only a few degrees ended the last ice age, another warming like that could have a catastrophic effect on the earth and its creatures, including us. In order to stop global warming, much must be done. The first thing to do to control the earth’s temperature is to lower the burning and/or the emissions of fossil fuels because that is the single most responsible cause of global warming. The downfall is that after the global warming process has started, it is very hard to reverse it. Global warming temperatures grow exponentially, and we will have to create an answer for global warming sooner than people think. I don’t know how to start the process of burning fewer fossil fuels. All I know is global warming must be stopped if we want to keep living the way we do now. If it isn’t stopped, the problems discussed will only get worse and the ending result will ultimately be death.
