South Korea is not the only place suffering from the scorching weather,...as countries around the globe have been experiencing heatwaves.<br />Especially in the northern hemisphere, new records for boiling temperatures have been set in July. <br />So what are the reasons behind such extreme weather? <br />Kan Hyeong-woo explains. <br /> This summer has been extremely hot across the northern hemisphere.<br />The U.S., Canada, Algeria, Norway and Japan have been seeing record-breaking temperatures for the month of July and extreme heatwaves over the past two months.<br /><br /> In Oman, there was one night in June when the lowest it got was 42-point-6 degrees Celsius, which is believed to be the highest "low" ever recorded.<br /><br /> Experts say the record-breaking temperatures can be explained by rising concentrations of greenhouse gases, which are a major cause of global warming.<br /><br /> "So the biggest reason for these extreme heatwaves is climate change, which is a result of global warming. In climate change, the main effect is rising temperatures. The overall temperature of the earth keeps going up, but the change gets bigger every year."<br /><br /> The World Meteorological Organization predicts that, at this rate, the number of so-called heatwave days will double by 2020 and quadruple by 2040.<br /><br /> "The past June marked the second warmest month on record globally,… but experts say that the worst of the heatwave may soon be behind us as we approach August."<br /><br /> "The heatwaves are likely to continue, but we probably won't see the extreme temperatures of over 36 degrees Celsius we've had since last weekend. I think the heatwaves in Korea will die down... because the North Pacific anticyclone tends to shrink in early August." <br /><br /> The latest typhoon, Jongdari, is heading towards Japan and may affect the Korean Peninsula, but the Korea Meteorological Administration says the storm's course could change.<br />Kan Hyeong-woo, Arirang News <br />
