On Monday, the United Nations released a new report that shows weather-related disasters in the past two decades have . A warning was also issued that the frequency and impact of such events are set to rise, according to The New York Times.

The numbers were provided for a United Nations-backed climate meeting that has a scheduled start date of next Monday in Paris. More than 120 national leaders will discuss the possibilities of keeping greenhouse gas emissions in check and solutions to slow the rise in global temperatures.

in the past 20 years, according to the UN Report, however, China and India have been the most severely affected, bearing floods that impacted billions of people.

More than 367 people died and nearly 2,000 were injured when a strong earthquake hit southwest China's mountainous Yunnan province, bringing homes crashing to the ground and sparking a massive relief operation.

In addition to the hundreds of thousands dead, the disasters left 4.1 billion others wounded, displaced, or in need of emergency assistance.

An average of 335 weather-related disasters were recorded every year over the past two decades, which doubles that of the previous 10. The report entails events that kill 10, affect more than 1,000, and generate appeals for outside assistance.

Margareta Wahlstrom, the head of the disaster reduction office, stated that the findings, “underline why it is so important that a new climate change agreement emerges,” from the summit meeting in Paris.

With reference to the rising ocean temperatures and melting glaciers as drivers of extreme weather, Wahlstrom suggested that reducing greenhouse gas emissions would help reduce the massive damage and losses inflicted by climate-influenced disasters.

Strong evidence points to a warming climate having a helping hand in more frequent and intense heat waves, which, in turn, cause heavier rains, worse flooding, and intensifying droughts in some areas. Yet, linkage to other types of weather events is much less clear.

Floods were responsible for nearly half of the weather-related disaster totals, affecting 2.3 billions, mostly in Asia. Storms had the highest influence on loss of life, killing 242,000, including the 138,000 killed by Cyclone Nargis, striking Myanmar in 2008. The cyclone noted as , according to TIME.

Droughts affected over a billion people over the past 20 years, causing hunger, malnutrition, disease, and agricultural failure, the report stated.

Heat waves reached a death toll of 148,000, most of which in Europe, while wildfires emerged as a new climate risk. In the United States alone, an estimated 38 major wildfires affected 108,000 people and caused $11 billion in losses, a number that will surely go up due to the fires that occurred in August -- which was the cutoff point for data in this specific report.

The amount of $1.9 trillion cost of disaster worldwide was accumulated by the Center for Research on the Epidemiology of Disasters, based in Belgium. The estimated figure was noted as a minimum, however. Data was available for only a little more than a third of recorded disasters.
