|Flood Damages in Verviers, Belgium (mk.co.kr)|
Recently, severe floods and heat waves have occurred throughout the world more regularly due to abnormal climate changes. Especially in Western Europe and Asia, many dead and missing have been reported due to natural disasters. On July 22nd, the worst floods in 40 years occurred in India’s western state of Maharashtra. It caused the deaths of over 150 people, and hundreds of people were missing. In Belgium and western Germany, floods occurred from July 14th to 15th and on the 25th, roads were closed down, cars were carried away, over 205 people died, and 176 people went missing. The situation is becoming more serious due to heat waves. On July 10th in western Canada, more than one billion sea creatures including mussels, clams, and starfish died en masse. Heat waves also brought mega forest fires to 12 states in the western United States, and forests of approximately 6,063km2, which is 10 times the size of Seoul, burned down. These unprecedented abnormal climate changes happened because global warming is making the North Pole glaciers melt at a rapid rate. Lately, the Arctic region has been warming more than three times faster than the mid-latitudes. This makes the jet stream that blocks the cold air of the Arctic region coming down to the south weaker. When the jet stream gets weak, air does not flow as well, and cold or hot air stays in the same place for a long time. The floods and heat waves seem to be occurring because of stagnant low pressure and a heat dome influenced by the jet stream.
