Climate Change in my Home Country, China by a City Tech Blogger

 

Climate change is a globalized situation and it will affect everyone who lives on this planet. When I was a child, this was the first globalized environmental issue I learned about and it is commonly everlasting. To be honest, people like to get used to it and mention the word “climate change” in class, and put it in our textbook as a concept. However, it has absolutely changed our life slowly day by day.

I was born in China and lived there for about 17 years. China is a large country physically, with large land and a large number of people and it is located in the north of the earth. As the third-largest country in the world in terms of land area, it has a diverse climate and terrains, which means one little change in the climate can cause some huge reactions in many ways. The general trend of climate change is warming year by year due to the release of carbon dioxide. In terms of geography, the warmer climate will cause drought. The negative change in the environment will cause damage to agriculture. Then multiple bad results in economics will follow. An unstable society definitely makes the situation worse. The change in climate is so small that you can not feel it in days, but if we use the year as the scale and check the data, we will find the climate is actually rising. In the last ten decades, the average warming of land areas in China was 0.9°C – 1.5°C, and the coastal sea level rose at a rate of 2.9 mm/a over the period 1980 to 2012, also increasing the frequency of regional extreme weather and climate events.

The biggest challenge is how to deal with issues caused by climate change. Agriculture, economic, political, people and society, all these terms are relatives and affect each other. In agriculture, climate change has caused the lower yields and quality of some crops, lower quality of arable land, higher fertilizer and water costs, and increased agricultural disasters. Warmer environments help increase agricultural pests and damage further. In China, there is a multi-decade infrastructure mega-project called the South-North water transfer Project. It means the extraction of abundant water resources from China’s Jianghuai River Basin to North and Northwest China. However, under the impact of climate change, the water area shrinks further, the average annual evaporation in each basin increases, and the adjustable water volume decreases compared with the planning period. In human health, the heat-waves and high temperatures brought by climate change provide a more suitable environment for germs and parasites, damage human immunity and resistance to diseases. In 1998, Shanghai experienced 4 heat waves. The total number of deaths during a heatwave can be two to three times higher than during a non-heatwave. What’s more, the direct economic losses due to climate change have a clear upward trend. Since the 21st century, the direct economic losses caused by meteorological disasters in China are equivalent to about 1% of GDP, which is 8 times higher than the global average during the same period. From 1990 to 2013, the average annual direct economic losses from meteorological disasters have increased 2.6 times compared to 1965-1989. Since 1989, it has increased 2.6 times.

We might not have much of a chance to feel the big change due to global warming at the country level, but when I look back, I actually feel the change. I lived in Guangdong when I was 5. compared to that year it is, now harder to get cold in winter, or I can say, harder to enter the winter. The weather in Guangdong is changing everyday. Yesterday it was almost 20 degrees, but the next day it was 5 degrees. It happened during the whole winter. I remember there was a year I still wore a short-sleeved shirt in January. The days I take my coat out are decreasing. But the temperature often changes in a day which is when I generally get a bad cold. This is not a big deal but in my opinion, it might be the most direct way to feel the climate change for normal people.

  1. It is important to acknowledge the severity of climate change. Individuals need to start believing in science, as well as the rapid change occurring in the world around us. The effects of climate change will continue to expand over these next few years drastically. Regardless if the entire globe stopped the emissions of climate change, we would still experience its effects for the next 1,000 years. As you stated the city should start to focus more of its efforts on environmental sustainability for the sake of business, community and the ecosystems. People need to comprehend that climate change is like dominos. One factor affects the next and the cycle continues, however, we must stop this continuous cycle before it is too late. As analysis continues to demonstrate more evidence indicates that rising sea levels is a standing issue. Sea level rise is very concerning because it includes erosion of beaches, inundation of deltas as well as flooding and loss of many marshes and wetlands. As I stated previously, climate change is a domino effect. As the emissions of greenhouse gasses continue, that means the global temperature rises. In addition because water vapor is the number one factor of greenhouse gasses the sea levels will continue to rise it is a continuous loop. I agree with your opinion that the biggest challenge is how to deal with these issues accordingly. Climate change does also affect agriculture, economics, politics and other members of society. Therefore, this should influence individuals to work together and better our planet. People really need to educate themselves regarding these issue as soon as possible.
