On October 12, the United Nations Office for Disaster Risk Reduction said weather-related disasters have seen a sharp increase in the past 20 years, with the number of reported disasters has increased from more than 4,000 in the period 1980-1999 to 7,348 in the period 2000-2019. In a report released a day before the International Day of Disaster Risk Reduction (October 13), the United Nations Office for Disaster Risk Reduction said Asia was hit hardest by Natural disasters, and heat, will be the biggest dangers that humanity will face in the coming decade. The report also "confirms that extreme weather events have dominated the natural disaster scene in the 21st century." During 2000-2019, 7,348 natural disasters occurred, killing 1.23 million people, affecting 4.2 billion people - many of whom suffered natural disasters more than once, and resulting in a global economic loss of about $ 2,970 billion. In the previous two decades, from 1980 to 1999, there were 4,212 disaster-related disasters worldwide, killing more than 1 million people, affecting more than 3.2 billion people, resulting in economic loss is about 1,630 billion USD.

The increase in the severity of natural disasters is explained by an increase in climate-related disasters, including extreme weather events, increased from 3,656 during 1980-1999 to 6,681 climate-related disasters in the period 2000-2019.

The United Nations Secretary-General for Disaster Risk Reduction Special Representative Mami Mizutori said that "we intentionally sabotage. That is the only conclusion one can come to when considering the facts natural disaster events over the past 20 years. "

Mami Mizutori said the double increase in extreme weather events in the past 20 years shows the need for a new approach to disaster risk management if the world wants to limit the damage caused by natural disasters.
The special representative of the United Nations Secretary-General for Disaster Risk Reduction stressed that "we can isolate ourselves from COVID-19, in one way or another, but we cannot isolate ourselves from these extreme weather phenomena due to rising temperatures, even in developed countries, let alone developing countries. "

Meanwhile, public health expert at the Center for Disaster Epidemiology at the Louvain University of Belgium, Debarati Guha-Sapir said "heat waves will be our biggest challenge in 10 next year, especially in poor countries. If this increase in extreme weather events continues over the next 20 years, the future of mankind is really bleak. "
