Beijing, Nov. 1 (Xinhua) comprehensive report, the World Meteorological Organization released a report on October 31, pointing out that 2015 to 2021 may become the hottest seven years on record. At the same time, it warned that the record atmospheric greenhouse gas concentration and heat accumulation have pushed the earth to an unknown field

it is reported that the preliminary climate report released by the World Meteorological Organization on the occasion of the 26th United Nations climate change conference said that global warming caused by greenhouse gas emissions may have a “far-reaching impact on contemporary and future generations”

the report analyzes the climate information and data for the first nine months of 2021. The report points out that the past seven years are becoming the hottest seven years since meteorological records

data show that the global greenhouse gas concentration has reached a new high in 2020. The concentrations of carbon dioxide, methane and nitrous oxide are 149%, 262% and 123% higher than those before industrialization, respectively, and this growth continues in 2021

in his statement on the report, UN Secretary General guterre said: “from the depths of the ocean to the top of the mountains, from glacier melting to extreme weather, the global ecosystem and all communities are suffering damage. The 26th UN climate change conference must become a turning point for mankind and the earth.”

the report shows that the deterioration of the climate situation leads to frequent extreme weather in many parts of the world. For example, at the summit of the Greenland ice sheet, it rained, not snow, for the first time

glaciers in Canada melt rapidly. The heat wave in parts of North America pushed up the temperature of a village in British Columbia, Canada to nearly 50 ℃. The temperature of death valley in California reached 54.4 ℃

many parts of the Mediterranean have experienced record high temperatures, and hot weather is often accompanied by devastating fires

extreme rainfall also hit many countries in Asia and Western Europe, causing floods and causing heavy casualties and property losses. The subtropical region of South America suffered from drought for the second consecutive year, affecting agriculture, transportation and energy production

the report points out that droughts, floods and other extreme weather events are hitting those who are most unable to recover and adapt, such as residents in Afghanistan, Central America and other places

World Meteorological Organization Secretary General Petrie Talas said that extreme weather events have become a new normal

he said: “more and more scientific evidence shows that climate change in some of these regions is caused by human activities.”

according to the current growth rate of greenhouse gas concentration, by the end of this century, the global temperature will far exceed the target set in the Paris Agreement, that is, the increase of temperature will be controlled within 1.5 ℃ to 2 ℃ compared with the pre industrialization level
