More years have gone, natural disaster happen a lot and the strength and damage that natural disaster made are growing than the past. Especially, in 2023, since the start of the year, a lot of natural disaster happened in anywhere around the world. Many people damaged and the damaged places and reminds are still not recovered clearly. Because the results of natural disaster are savage. So, firstly, let's talk about meaning of ‘Natural disaster’. Natural disaster is an inevitable phenomenon that make harm of anywhere, for example, floods, droughts, heavy snow, etc. Since a long time ago, there have been natural disaster. However, in recent, a natural disaster is being savage, big, and are happening more a lot. Why nature change and make damage a lot in recent?
   About that issue, experts give their opinions from various perspectives Someone said the reason is that quick melting of North and South pole’s ice. North and South pole’s ice melted a lot, then the height of ocean goes up, so nature can’t do well their jobs, and the nature's balance cannot maintain. And some others said the reason is that severe increase in temperature for very short years in recent. And others said that the change and big natural disaster are just a period of earth change. These various opinions have a similar point. What is i? It is that “Nature change so quickly in recent year, compared to the past”.
   The index of lots of climate extreme change, such like the degree how the temperature has risen, the degree how the height of ocean has risen. Of course, the temperature has risen steadily. However, the point is “speed”. Compared to past.
   For example, in 2023, Hawaii forest fire occurred and spread quickly and largely. In 2023, August, the great forest fire started in Hawaii, US media mentioned that this occurrence is the second largest damage of human life caused by forest fire in US. This forest fire, analyzed by experts, is the result of dry forest, plants, strong wind because of hurricane and low humid weather than usual. Meanwhile, NYT meteorologists analyzed that the reason of forest fire is “an abnormal weather”. In case of Hawaii, the weather is humid, hot. However, for the recent years, the weather and the temperature changed a lot. The amount of rainfall in summer has decreased a lot, and the drought has intensified. And the change of forest also affects to make bigger forest fire. Foreign plants increased, and it let increase the spread of forest fires. Because it has characteristic that casy to bum by fire. Experts see there are various reasons such man-made and natural factors. Meanwhile, the NYT pointed out that because of global heating, now there is no area that can be protected from the heating of the Earth. Because before this case, nobody thought that the site of a very lange Hawaiian forest fire can be burned.
   Next, second case, Canada forest fire happened. Canada forest fire started in 2023 May. However, still they have not extinguished completely. Firefighters gave up the part of fire extinguishing. In Canada, there are over 1,000 numbers of fire still continue, among over 1,000 cases, about 650 guished. Jonathan Wilkinson, the Minister of Natural Resources, looks at the situation, that maintenance cases are in situation that hard to be ext of warm, dry weather made strong forest fire and high frequency of fire in nation. Experts are also secing the Canadian forest fire as a phenomenon caused by unusual weather conditions.
   Finally, included Korea, other lots of country around the world, get damaged by the big amount of rain, that said severe flood. Why do flood’s precipitation and damage increase than the past years? Present, when floods record high precipitation and severe result for each year, the reason why the floods are getting stronger is also largely related to the increase in greenhouse gases and changes in climate. More temperature higher, the atmosphere can hold more air. According to a spokesman for the Korea Meteorological Administration from BBC Korea, in Korea, winter shorten and summer lengthen because of change of climate. Add to this opinion, a spokesman said, in summer, there is a lot of steam in the atmosphere, so it affects severe flood. The world is hotter than the past, so everywhere around the world, not only Korea, but also Western Europe, Africa, the United States, etc, are recording severe flood in recent.
   If someone asks why are these situations happening? Then we can say, “These are because of the rapid change of climate.” More scarch the specific reason, then we can find that the reason of the climate’s rapid change is a steady increase in carbon emissions. More emissions be emitted, more arth be hotter. If Earth is boiled, then the carth maintains that increased temperature. According to a climate crisis expert who recently appeared on a program called You Quiz, in the past, the phenomenon of the Earth heating was called "WARMING." followed by "HEATING, and now “BOILING." In other words, it is now too late to prevent climate disasters. In the future, we have to work hard to deal with climate disasters.
   WMO said in a press release on May 17, 2023 (local time), "There is a 66% chance that global average annual temperatures will rise by more than 1.5 degrees before 2027 compared to before the Industrial Revolution.” In other words, by the 1.5-degree limit on global temperature rise. Many experts say it is 2027, there is a very high possibility of a year exceeding already too late to deal with climate disasters. But we must act to survive the climate disaster, to reduce the myriad victims at all and to slow climate change.
