GLOBAL WARMING

 Introduction

The entire environment, including the oceans, ice sheets, and other features of the environment, is gradually heated as a result of global warming. There has been a noticeable global rise in atmospheric temperature in recent years.

 The Environmental Protection Agency estimates that over the past century, the average surface temperature of the Earth has risen by around 1.4 degrees Fahrenheit (0.8 degrees Celsius). Additionally, it is predicted that over the course of the next century, global temperatures could rise by 2 to 11.5 ° Fahrenheit

Causes of global warming

 There are numerous reasons for global warming, some of which are natural and some of which are caused by humans. The primary contributors to global warming are greenhouse gases, which are created both by certain natural and human-made processes.

 The rise in population, economy and energy use over the 20th century contributed to an increase in the concentration of greenhouse gases. In order to meet practically all of the demands for industrialization in the modern world, a variety of greenhouse gases are being released into the atmosphere through numerous industrial processes. Carbon dioxide (CO2) and sulfur dioxide (SO2) gas emissions have multiplied ten-fold in recent years. According to various industrial and natural activities, such as photosynthesis and oxidation cycles, carbon dioxide gas emissions might vary.

Another greenhouse gas produced by the anaerobic breakdown of organic molecules is methane, which is released into the atmosphere. Other greenhouse gases include compounds containing chlorine and bromine, halocarbons, chlorofluorocarbons (CFCs), oxides of nitrogen (nitrous oxide), and others that accumulate in the atmosphere and disturb the atmosphere's radiation balance. They serve a purpose in heating the Earth's surface by absorbing heat radiation.

Ozone depletion, which results in a hole in the ozone layer above Antarctica, is another factor contributing to global warming. The ozone layer is continuously deteriorating as a result of the discharge of chlorofluorocarbon gas. Global warming is a human-caused phenomenon. The steady emission of chlorofluorocarbon gas, which is utilized in many areas as an aerosol propellant in refrigerators and an industrial cleaning solution, causes the ozone layer in the atmosphere to deteriorate.

Sunlight from the sun's rays cannot reach the earth's surface because of the ozone layer. The ozone layer's steady deterioration is a crucial indicator of the Earth's surface warming, though. The biosphere is being exposed to harmful ultraviolet sun rays, which are then absorbed by greenhouse gases and contribute to global warming. The results indicate that by 2000, the size of the ozone hole is expected to have doubled from that of Antarctica (over 25 million km). The ozone layer doesn't seem to deteriorate more or less throughout the winter or summer.

The Earth's surface temperature is also rising as a result of the abundance of different aerosols in the atmosphere. Aerosols in the atmosphere scatter solar and infrared rays, which cool the earth and warm the air (absorbed). Additionally, they have the power to alter the microphysical and chemical characteristics of clouds, as well as perhaps their lifetime and range. Human activity is a contributing factor to the atmosphere's expanding volume.

Dust is produced by farming, soot particles are produced by burning biomass, and aerosols are produced by industrial processes that involve burning various goods during the manufacturing process. Transport-related emissions produce a variety of contaminants, which are then transformed into aerosols in the atmosphere by a number of chemical processes.

Effects of Global Warming

 The impacts of global warming have been increasingly obvious in recent years as a result of rising global warming causes. Only 25 of the 150 glaciers that were once present in Montana's Glacier National Park are still there, according to the US Geological Survey, as a result of the growing effects of global warming. Hurricanes are becoming more strong and more hazardous due to widespread climate change. Natural storms gain strength by absorbing energy from temperature variations (cold upper atmosphere and warm tropical ocean). According to records, 2012 was the warmest year since 1895, while 2013 surpassed 2003 as the warmest year.

Numerous climatic changes are brought on by global warming, including longer summers, shorter winters, higher temperatures, altered air circulation patterns, jet streams, year-round rain, melting snowflakes, loss of the ozone layer, severe storms, and cyclones, floods, and droughts, among many other effects.

How to Reduce Global Warming

 Governmental organizations, company executives, the private sector, NGOs, etc. have all run and carried out several awareness initiatives and activities to lessen global warming. Some damages caused by global warming are not compensated by the solution (Such as melting snowflakes). However, we shouldn't give up and keep working to lessen the human causes of global warming in order to lessen its impacts.

We should make an effort to lessen the number of greenhouse gases we release into the atmosphere and adapt to long-term climate change. We should aim to employ renewable energy, such as energy produced by solar, wind, and geothermal sources, rather than electric energy. Reducing the amount of coal and oil burned, the use of transportation equipment, the usage of electrical equipment, etc. can significantly reduce global warming.
