Explanation The Effects Of Human-Induced Climate Change Around The World”
If people who had been in Hanoi on July, they would have recognized that this summer was unusually cool. The normal situation would have been hot and humid since Hanoi is located in low latitudes. In contrary, countries placed in high latitude such as Norway recorded a heat more than 30-degree Celsius. According to The Guardian, the Arctic Circle jet stream (a wind that drifts fast in strips at the top of the atmosphere) weakened, causing a ‘heat dome’ throughout Eurasia. Damage is continuing due to prolonged record heat wave that hit the northern hemisphere. If people who had been in Hanoi on July, they would have recognized that this summer was unusually cool. In this way, it is evident that the phenomena that have not happened often in the past have occurred frequently. We cannot deny that all of the circumstances are caused by global warming. After the industrial revolution, the concentration of greenhouse gas such as carbon dioxide began to rise. Carbon dioxide emissions rose about 0. 6ppm in 1960 to about 2. 3ppm over the past decade, nearly four times. Of course, the growth of greenhouse gases is not necessarily due to industrial activity, but it is true that the Industrial Revolution changed our lifestyle a great deal, resulting in an exponential increase in the gas emissions.
The responsibility for the human-enhanced greenhouse effect lies solely on people, and the consequences have come back to us, climate change. We face various forms of climate change every year, such as hurricanes, droughts, and extremely cold weather. Among them, hurricanes affect people in the most direct form and are destructive. In 2017, Hurricane Irma hit the United States in the Florida area, causing astronomical damage. Hurricane Ima has reached 297 km / h in wind speed and has grown into a category 5 hurricane as it moves inland. Nearby island nations including Barbuda Island and Antigua Island suffered blackouts which stop electricity supply, and most of the house roofs were blown away. Some experts have pointed to climate change as the hurricane is getting stronger annually. Rise sea level caused by global warming is considered to be the first factor of the strong tropical cyclone, including the case of hurricane Irma. It increases the occurrence of storm surges and flooding. Over the past decade, sea level has risen more than 15 centimeters. This means that a higher storm surge than 10 years ago could be more destructive and mighty. Moreover, the warmer sea surface is also a negative factor. Warm seawater surfaces, wet conditions, and sea level rise cause air to rise, eventually creating tropical cyclones. Although the tropical cyclones dissipate the equatorial heat energy to other regions and spread the rain to maintain the ecosystem, we seriously have to consider the cause of cyclones that are becoming more and more powerful in relation to global warming.
As mentioned earlier, rising sea levels have caused climate change. Then, you can think of one question here. What is the cause of rising sea levels? The direct cause of sea level rise is the melting of polar glaciers. Antarctic glaciers have 90% of the global freshwater, and if they melt, sea level can rise to a maximum of 60 meters, resulting in most island countries and coastal cities sunk into the sea. The story above is not just speculation, but there are many places on earth that actually happen. Toobaloo is a small country located at the center of the South Pacific, less than 2 meters above sea level. Since 1993, the sea level of Toobaloo has risen over 9 cm, and two of the nine islands have already submerged under the water. Experts expect that at this rate, the entire area will sink in a few decades. After all, in 2013, the country has declared a national crisis and has become a climate refugees who are leaving their lives. Due to the positive feedback of an increase in temperature caused by the emission of CO2 from other developed countries, more glaciers melt and the sea level rises. Thus, 44 island nations including Toobaloo now are in danger of submergence. Heatwave is known to bring about the greatest death damage among all weather disasters. When exposed to high temperature for the longest time in our body, heat stress increases the burden of the heart and causes cell damage.
In addition, in the local farmhouse with the heat, crops are killed. Crops for commercial agriculture are particularly damaging, Many livestock is also dead. Due to the high-temperature phenomenon, mass popping occurs in fish farms, which causes astronomical damage. On the other hand, in cities, there were frequent blackouts. Electricity usage due to heat As the voltage increased, the transformer failed. Even high-temperature dryness can cause large-scale forest fires. According to the Proceedings of the National Academy of Sciences, human-induced climate change has affected forest fires in the western United States over the past three decades, resulting in double the incidence of forest fires. The additional damage caused by forest fires not only has long-term adverse effects on the respiratory system but also burning on snow and ice reduces the albedo effect.
