Almost all parts of the world are being hit by a variety of natural disasters in succession, including flood, drought, heavy snowfall and biting cold caused by abnormal weather conditions.

Early last April, heavy rains and flood struck East Java of Indonesia.

A river overflowed to submerge thousands of houses and force 11 880 residents to leave them.

In March, the worst flood in 50 years hit the east coast of Australia, damaging hundreds of houses and compelling thousands of locals to evacuate their residential areas.

Late last February, a torrential rain deluged Kagera, Tanzania, leaving some 300 families homeless, demolishing dwellings, rooting out trees and destroying the infrastructure including roads and bridges.

On the other hand, severe droughts wreaked havoc on 749 000 square kilometres of area in Yunnan, Guizhou, Sichuan and other provinces and autonomous regions of China, while about 2.1 million people are asking for emergency supplies due to droughts in Somali, Ethiopia.

The unprecedentedly heavy snowfalls and intensive cold early in many countries this year clearly demonstrated the seriousness of abnormal climate.

In January, a snowstorm with a velocity of nearly 100 km per hour in Miyagi Prefecture, Japan, caused a series of traffic accidents and a dozen casualties.

The snowfall amounted to 120 cm, a record high since 1986, in Toyama Prefecture, Japan.

Spain suffered the largest snowfall in 100 years and declared Madrid and other regions as afflicted areas.

Different parts of Sweden and Latvia fell into disorder after a great amount of snow fell.

Experts assert that dramatically abnormal climate would continue across the world in future, ascribing such disasters to global warming.

According to a report released by the United Nations, the world has seen about 7 350 cases of catastrophic natural disasters for over two decades until 2019 and 1.23 million people were killed and 4.2 billion suffered from them.

The number of disasters caused by extreme weather rapidly increased during that period, the report said, adding unless measures are taken to check global warming, the atmospheric temperature will go up by over 3.2 degrees centigrade in the coming ten years.

The World Meteorological Organization already warned that the global average temperature reached a record high of 14.9 degrees centigrade, which is 1.2 degrees higher than that before the industrial revolution. The UN secretary general expressed concern that the temperature rise is approaching to such an extent that it might invite a terrible catastrophe.
