Write 5 pages thesis on the topic the heatwaves.
.One of the most significant and the most reputed organization is the World Meteorological Organization (WMO). WMO is the specialized agency of the United Nations. As per the WMO, there are several reasons for climate change in the global environment. One of them is ‘Greenhouse gases.
Several gases are regarded as greenhouse gases. One of them is the water vapor, the concentration of which is observed to be the maximum among all the greenhouse gases. Another component of gas is carbon dioxide (CO2).
Since the industrial revolution, the earth’s level of CO2 has increased by 30% (World Meteorological Organization, “Causes of Climate Change”). Moreover, methane gas is also an essential greenhouse gas on earth. It is more harmful than CO2 as it absorbs more heat than CO2.
Further, nitrous oxide is also considered a greenhouse gas. This gas is mainly emitted through the fertilizers used in the agricultural processes. Furthermore, a human-made gas, namely, chlorofluorocarbon (CFC), is also considered a greenhouse gas.
CFC is majorly used in the industrial sector. It is extensively used in refrigerators and air conditioners (World Meteorological Organization, “Causes of Climate Change”). .
Besides greenhouse gases, there are also specific causes for the climatic change on the earth. According to the WMO, one such aspect is the presence of aerosols in the atmosphere. Aerosol absorbs the solar rays, mostly the infrared and, scatters those rays in the earth’s atmosphere. Furthermore, aerosol also changes the chemical and the microphysical nature of the cloud and hence, alters the possible lifetime of the cloud.
This may result in scarce rainfall or a climate of extreme rain (World Meteorological Organization, “Causes of Climate Change”).
Another aspect, as mentioned by WMO, regards the causes of climate change in the changing pattern in the usage of land by humanity. The extreme deforestation for industrial growth, agricultural lands, households, and many more has reduced the forest cover. This has made the sun rays directly fall onto the earth’s surface, and hence, the temperature of the planet has significantly increased (World Meteorological Organization, “Causes of Climate Change”).
The world has observed some of the devastating impacts of the heat waves in this era. This has significantly affected the people, infrastructure, and natural system of the earth. The most significant evidence is seen in the rise in the average temperature of the planet. According to the National Oceanic and Atmospheric Administration (NOAA), there has been a rise of 0.8 degrees Celsius globally. .
