Global Warming

What is Global Warming?

This is the absolute increase of earth’s average surface temperature following the effects of greenhouse gases like carbon dioxide emissions from burning fossil fuels as well as from deforestation which basically traps heat that would escape from the earth’s surface. Generally global warming refers to a gradual increase in the average temperature of the earth’s atmosphere and its oceans, a great change that is of high concern to be changing Earth’s climate permanently. Great debates have been held on weather global warming is real. The Climate Scientists focusing on the data and facts agree the planet is definitely warming. Most people view the effects of global warming to be of greater substantial and more frequently occurring, scientific consensus on the climatic changes targeting global warming is that, the average temperature of the Earth has gone up between 0.4 and 0.8 degrees over the gone 100 years[1]. The risen volumes of carbon dioxide and other greenhouse gases released by burning fossil fuels, agriculture and land clearing are considered as the primary sources of global warming that have taken place over the gone 50 years.

The cause of global warming

The earth’s climate is adversely influenced by the first 6 miles which comprise most of the matter making up the atmosphere. Global warming occurs when carbon dioxide together with other air pollutants and greenhouse gasses collect in the atmosphere as well as absorb sunlight and solar radiation which have actually bounced off the earth’s surface. Basically, this radiation would eventually escape into space but these pollutants that can stay for years to centuries in the atmosphere trap the heat and cause the planet to get hotter. Curbing dangerous climate change needs deep cuts in emissions accompanied by the use of alternatives to fossil fuels worldwide.

How much have human beings increased the Atmosphere’s Carbon dioxide Concentration?

Human beings have contributed to an increase of carbon dioxide concentration in the atmosphere by a percentage of 30 which is a huge significant increase, even on inter glacial timescales. It is mostly considered that human beings are responsible for the increase since the increase is perfectly correlated with the rising fossil fuel combustion and changes in the ratios of various carbon isotopes in atmospheric Carbon dioxide are persistent with anthropogenic emissions. Combustion of fossil fuels especially for transportation, electricity generation, heating and manufacture of cement all accumulate to the total worldwide emission of around 22 billion tons of carbon dioxide to the atmosphere every year[2]. Almost a third of this is concentrated on electricity generation, and a third from transportation and the trend applies to all other sources. The huge input of carbon dioxide is leading to the atmospheric levels of carbon dioxide to dramatically rise. Based on the graph, the carbon dioxide levels over the gone 160 thousand years rose to medium lengths. The recent level and projected rise over the coming hundred years with no curbing of emissions might cause the graph to curve to lower heights.

How global warming is linked to extreme weather

Scientists report that the earth’s intensifying temperatures are fueling longer and hotter heat waves, heavier rainfall, more frequent droughts as well as more powerful hurricanes. The reports also stated that odds of similar droughts taking place in future had extremely doubled over the gone century. In the year 2016, the National Academies of Science, Engineering, and medicine stated that it’s possible to attribute certain weather events such as heat waves, directly to climate change. The earth’s ocean temperatures are becoming warmer meaning the tropical storms can pick up advanced energy. Global warming could definitely turn category 3 storm into a more terrible 4 storm. Impacts of global warming are actually being identified across the globe. Adverse heat waves have caused tens of thousands of deaths across the world.

Other Effects of global warming

  • Dramatic water shortages and intensified risk of wildfires in the American West are caused by Melting of glaciers, early snowmelt as well as severe droughts.
  • The rising sea level causes coastal flooding on the Eastern Seaboard mainly in Florida and places like the Gulf of Mexico.
  • The forests, farms as well as cities will come across troublesome new pests, heat waves, heavy downpours accompanied by uprising flooding. All these factors will cause great damage to agriculture and fisheries.
  • The disruption of habitats like coral reefs and Alpine meadows could lure or rather drive most plant and animal species to extinction.
  • Asthma, allergies and infectious disease outbreaks will be expected frequently due to the risen growth of ragweed pollen producing plant, greater levels of air pollution as well as the spread of pathogens and mosquitoes favoring conditions.

Where United States stand in terms of global warming contributors

Recently, China has led in global warming pollution, producing a percentage of 28 of all carbon dioxide emissions. This is quite very dangerous to the surrounding. It succumbs well being of many life leaving objects as a result. The United States follows closely behind China. A part from it making up 4% of the population of the world, it produces a whopping 16% of all the global carbon dioxide emissions as much as European Union and India in the third and fourth places respectively combined. For a nation having much population it is too bad to have such percentage of carbon dioxide emissions if not contributed by themselves. America is leading in cumulative emissions for the past 150 years[3].

What United States is doing to prevent global warming?

In the year 2015, the United states Environmental Protection Agency pledged to minimize carbon pollution from the power plants by about 2030, close to 2005 levels via its clean power plan. The United States Department of Transportation has held firm carbon pollution and the fuel economy standards which should cut emissions across the 2020s. Chemicals which contribute to global warming such as hydrofluorocarbons are phased out countrywide. Energy inefficient household items such as incandescent light bulbs are also phased out. In the same year, solar and wind power gave more than 5% of the United States’ electricity being the first time and construction begun on the nation’s first offshore wind power project[4]. Globally, within the United Nations conference on Climate change in France, about 195 nations comprising of United States came to agreement based on pollution cutting provisions with an ambition of preventing the average global temperature from rising to degrees above 1.5 degrees Celsius above preindustrial times.

Global warming a big threat, Can I tackle it?

To tackle global warming at personal level, several techniques can be used to achieve this, to begin, minimize your own carbon footprint through very promising steps; Make conserving energy apart and parcel of your daily activity and routine at large. Make conserving energy your decisions as a consumer. When you go shopping for appliances such as refrigerators, dryers and washers, search for products with the government’s Energy Star label. These products attain higher standards for energy efficiency than the least minimum federal requirements. When you purchase a car, search for the one with the leading gas mileage and lowest emissions. You could as well minimize emissions by taking transportation or rather carpooling if possible. Very comfortable, taking notice of where you dispose off your waste products. Limiting your use of inflammable flames is also a good technique. At house hold level, the use of coal should be reduced to no left percentage, very good cooking appliances with no much emission exists. We can control this use of coal which is very dangerous even at room temperature as it remits carbon dioxide in more percentages to the environment[5].

Conclusion

Generally global warming is hazardous more so to nations where emissions of carbon dioxide are greater like in United States and China. Global warming has adverse effects on the climate, human beings, animals, plants, seas and oceans. Pollution takes the greater part in contributing to global warming following the analysis by scientists. The kind of appliances put into use, the kind of fumes remitted by our appliances, where and how we dispose our appliances. It is recommended that human beings be very selective while buying appliances, significantly certain features within these appliances to be bought must be considered and checked keenly before carrying them away. Global warming at large cause ill-health and disrupts most of the human activities. It is harmful based on the miserable effects it remits to the surrounding. Although most of the causes result from the human activities, it turns to be the most dangerous threat. Some of these human causes can be minimized but there are natural causes that are uncontrollable and they cause discretion. The United States scientists originating from the Intergovernmental panel on Climate conducting global warming research have currently predicted that the average global temperatures could rise between 1.4 and 5.8 degrees by 2100.
