“The era of global warming has ended; the era of global boiling has arrived.” - Guterres, the UN Secretary-General

The one thing we can immediately notice as a result of waste and overuse of resources is climate change. Climate change generally refers to the shifts in temperatures and weather patterns on the Earth—the same as global warming. All over the world are currently struggling with the effects of climate change. For example, experts have found a temperature abnormality in Pheonix, Arizona, arguing that the heat waves around this area are becoming hotter and hotter. As a result, many people living in Arizona died and got diseases, not being able to avoid the catastrophic circumstances. 

However, Korea is nothing different from the cases of Pheonix. According to the analysis using the accumulated data of 100 years, influenced by the warming earth, the temperature of seas surrounding the Korean peninsula is expected to significantly increase: about 2°C by 2060 and about a maximum of 4.5°C by 2080. In fact, the actual recent increase in sea temperatures in Korea is higher than the average increase over the countries. Moreover, the temperature increase rate is also higher than that of other countries: The global average temperature has risen by 0.07 degrees every ten years, but in Korea, it has risen by 0.2 degrees. Compared to the past 30 years, summer has been more extended, and winter has been shorter, with summer being longer by 20 days and winter being shortened by 22 days. Therefore, for now, it is difficult to say that Korea has distinct four seasons. 

Then, what has contributed to the reduction of winter days? As the air gets warmer, Korean people depend on the AC to alleviate the hot weather. Obviously, just using AC makes adverse effects on the environment; however, the serious problem manifested on the street where many stores and restaurants occupy. According to a recent survey from Korea Energy Agency (KEA), about 12% of them tend to turn on AC, opening the door. When this happens, the amount of electricity used would be 1.4 times more than the case closing the door as well as the increase in usage fee. Furthermore, this can be dangerous from the blackout since Korea struggled with the blackout in 2011 caused by energy deficiency. This research effectively shows the lack of recognition and efforts from the public. 

As a result of climate change, several regions in Korea grappled with heavy rain, which led to the collapse of dams and floods. Mostly, these disasters occurred in rural areas, so the treatments were harder to be applied. Like this, climate change cause unforeseen danger. In addition, climate change can be the main source of inequality following the result of climate change.
