Introduction

Global warming leads to a gradual rise in the surface temperature of the atmosphere and the waters of the Earth. Shift is increasingly affecting the atmosphere of the Earth and, as such, there are a number of issues surrounding the existence of global warming. Through means of data analysis and testimony, scientists conclude that the world is warming and, as such, gradually affects the lives of people and various sectors of the economy. This technical paper also addresses numerous research findings that reveals the occurrence of global warming and provides proposals aimed at mitigating global warming.

Discussion

Since the era of industrial revolution, human activities have led to a tremendous introduction of carbon dioxide into the atmosphere. The increase in the amounts of carbon dioxide concentrations leads to an occurrence of the greenhouse effect, which results from the absorption of infrared radiations by the earth_x0092_s surface and hence causing an increase in the atmospheric temperatures (Easterbrook 125). The increased atmospheric temperatures, in turn, lead to an increase in water vapor in the atmosphere, which absorbs infrared radiations. The increase in temperatures characterizes an alteration of atmospheric circulations and hence a change in the global weather patterns. Several scientific pieces of evidence show the occurrence of global warming as will be outlined in this technical report.

There has been an increasing level of the ice scores since 1950, which depicts an increasing level of global warming. Ice cores entail cylinders of ice drilled from glaciers and ice sheets. They are fundamentally frozen time capsules, which aids different scientists to reconstruct climate far into the past. Layers in ice cores often relate to years as well as seasons where the youngest ice stays at the top and the oldest ice at the bottom of the core (Booker 55). The warming trends are very worrying as they surround human activities. With earth-orbiting satellites, scientists have collected data about climate and planet on a global scale, and there have concluded that series of signals show that there is a changing climate. The Ice cores, drawn from Tropical Mountain, Greenland and Antarctica glaciers illustrate the response of the Earth_x0092_s climate to changes in greenhouse gas levels. Other evidence exists in the tree rings, coral reefs, and layers of sedimentary rocks among others. The evidence reveals that global warming occurs approximately ten times faster than the average rate of ice-age-recovery warming.

Shrinking Ice Sheets

There has been a decrease in the mass of the Greenland and Antarctic ice sheets. Based on the data obtained from NASA’s Gravity Recovery and Climate Experiment, the year 2002 and 2006 showed a loss of 150 to 250 cubic kilometers of the Greenland mass, that is an approximate cubic mile between 36 to 60. On the other hand, the Antarctica lost about 152 cubic kilometers of ice between 2002 and 2005. This is an evidence of the increase in the level of heat on the surface of the earth, global warming.

Extreme Events and Global Temperature Rise

There have been series of extreme events that show the existence of global warming. Essentially, a scientific consensus shows that global warming has risen from 0.4 to 0.8 °C over the last ten decades. The report by Booker on The Real Global Warming Disaster indicates that the temperatures would increase by 0.2 °C and 0.5 °C per decade (p. 49). As such, there has been an occurrence of natural phenomena such as La Niña and El Niño resulting from the effect of global warming. Besides, 2014 and 2016 were the hottest years and 9 of 10 of the hottest years has taken place during the 21st Century hence a show of an increasing impact of climate change. Over the years, the number of record high-temperature events has been increasing with a reduction in the number of record low-temperature events.

Geologic and Other Evidence

Notably, the intense interests in the cause of global warming have increased over the decades with different scientific trying to outline the possible evidence that shows the occurrence of the phenomenon. According to Weart, the evidence of global warming is not only the emission of carbon dioxide (Weart 12).

Geologic evidence of recurring climate cycles shows the occurrence of global warming. For instance, the great volcanic eruption of 1783 that took place in Iceland was an effect of global warming. Nevertheless, other scientists suggest that the evidence of global warming does not lie in the geology of volcanoes but rather on the oceans and sea levels (Weart 12).

The global sea level has risen by about 17 centimeters (6.7 inches) in the last century and double in the last decade.

Conclusion

Global warming entails, a steady increase in the average temperature of the atmosphere, as well as the oceans of the Earth and the change progressively, affects the Earth_x0092_s climate and as such, there exist series of concerns surrounding the reality of global warming. Through data analysis and evidence, scientists believe the planet is warming and as such, increasingly influences the lives of individuals and different sectors of an economy. Since the era of industrial revolution, human activities have led to a great introduction of carbon dioxide into the atmosphere. Scientific evidence of global warming include the rising temperatures, the shrinking ice sheets, the levels of ice scores, the warming oceans, glacial retreat and extreme events among others (Booker 48).

Recommendations to Reduce Global Warming

The following are the actions that individuals and governments across the world should undertake to reduce global warming.

  • There should be an expansion of the use of renewable energy and transformation of the global energy system to one that is cleaner and less dependent on coal and other fossil fuels and hence a reduction in the emission of carbon dioxide.
  • There should be an increase in the use of vehicle fuel efficiency and an adequate support for other forms of energy that reduce oil use hence reduction in the emission of carbon dioxide.
  • Different countries across the world should place limits on the amount of carbon that polluters are allowed to emit in different industries.
  • There should be a buildup of a clean energy economy by investing in efficient energy technologies, approaches, and industries.
  • There is a need to reduce tropical deforestation as well as its associated global warming emissions.
  • The world should foster adequate knowledge about global warming, its impacts and the need to curb it.
