Essay on greenhouse effect
Greenhouse Gas Emissions
In the U.S., our energy-related activities are known to account for three-quarters of our human-generated greenhouse gas emissions. These are usually expressed in the form of carbon dioxide emissions from burning fossil fuels. Also, more than half the energy-related emissions are known to come from large stationary sources. Of major importance are the power plants. Also, about a third of emissions come from transportation. Special role should be attributed to the industrial processes. These include: the production of cement, steel, and aluminum, agriculture, forestry, other land use, and waste management. The above mentioned things can be regarded as the important sources of greenhouse gas emissions in the United States. (The Big Heat: How Capitalism is Cooking the Earth)
A better understanding of where greenhouse gas emissions usually comes from the following the governments. The emission inventories are prepared at the federal, state and local levels. These institutions are known to track emissions from various parts of the economy. A whole thing pertains to the issue of transportation, electricity production, industry, agriculture, forestry, and other sectors. EPA is also known to publish the official national inventory of US greenhouse gas emissions. A whole issue deals with the latest greenhouse gas inventory results. The analysis of the year 2005 shows that the U.S. emitted over 7.2 billon metric tons of greenhouse gases. A whole thing has reached the equivalent of a million metric tons of CO2 equivalents (MMTCO2e). This sum is roughly equal to the annual GHG emissions of an average U.S. power plant.
Health and Environmental Effects
Climate change is also known to affect people, plants, and animals. The latest estimations revealed by the scientists show that there are many ways to understand future climate change. The overall effect is known to vary by region and over time. Scientists are known to observe some of the frequently recurring climate changes. The observed effects include sea level rise, shrinking glaciers, changes in the range and distribution of plants and animals, trees blooming earlier, lengthening of growing seasons, ice on rivers and lakes freezing later and breaking up earlier, and thawing of permafrost. The other important issue pertains to the issue of the Earth's environment. When properly tackled, this can help people to adapt themselves to present climate changes.
In the United States, scientists show the tendency to hold to the belief that most areas will to continue to warm. However, the research proves that some of the areas have the tendency to get warmer more than others. In general, the whole thing remains difficult to predict. Under such circumstances, the parts of the country tend to become wetter or drier. The other prediction made by the scientists is the increase in precipitation and evaporation. The other important expectation that are to happen is drier soil. The situation is typical for the middle parts of the country. Just the same can be told about Northern regions of the country. Alaska is just the case. According to the latest estimations, Alaska region is expected to experience the most warming
In fact, Alaska has been experiencing significant changes in climate. The tendency was evident during the recent years. It was the time when the country was mostly affected by the global climate change.
Human health is a thing that can be affected directly and indirectly by climate change. A whole thing is being realized through extreme periods of heat and cold, storms, and climate-sensitive diseases. These include such diseases as malaria, and smog episodes.
