Global warming aggravates natural disasters

Introduction: more than 100 experts and scholars at home and abroad engaged in Glacier and climate research gathered in Lanzhou recently to hold the international glacial society academic conference Experts at the meeting pointed out that the current 100 years is the highest temperature period in the past 1000 years Experts pointed out that with the global warming and the increase of greenhouse gas effect, the natural ecosystem in many areas of the world has been affected, such as sea level rise, glacier retreat, frozen soil melting, river (Lake) ice late freezing and early melting, etc Due to the limited adaptability, the natural ecosystem is vulnerable to serious and even irrecoverable damage The experts are from more than 10 countries and regions, including the United States, France, Canada, the United Kingdom, Russia and China Qin Dahe, former president of the international glacial society, President of the international glacial society, academician of the Chinese Academy of Sciences and director of the China Meteorological Administration attended the conference and made academic reports Some scholars put forward at the meeting that there are many causes of climate system change, which can be divided into two categories: natural climate fluctuations and the impact of human activities The former includes solar radiation changes, volcanic eruptions, etc.; the latter includes human use of coal, oil and other fuels Experts said that from the existing research, some extreme events closely related to global warming, such as El Nino, drought and so on, may increase in frequency and intensity, and cause more damage to natural systems The experts also discussed the latest progress of the research on the ice core in the third pole of the world, the research on the microorganism in the ice core, the research on the ice core in the north and south poles, and the research on the temperature record in the ice core.
