Alarming increase in the speed of sudden droughts on earth

According to IRNA on Tuesday; “Most people have heard of flash floods, but sudden droughts are not very popular,” wrote the Science Alert website. Unfortunately, however, this is changing, and the rate at which abnormal periods of sudden drought are emerging in warmer climates has increased.

A recent study on sudden droughts shows that sudden droughts have apparently accelerated in the last 20 years, with approximately 33 to 46 percent of sudden droughts occurring in just five years.

The phenomenon has occurred in several countries and regions such as the United States, Australia, China and Africa, and rapid drought conditions in the central United States emerged during the 2012 to 2013 North American drought within a few weeks.

Sudden droughts are more prevalent in humid and semi-humid regions such as Southeast Asia, East Asia, the Amazon Basin, Northeastern America, and South America, although they may occur outside of these regions.

The International Monetary Fund (IMF) says the frequency and severity of climate-related disasters in the Middle East and Central Asia are occurring faster than in other parts of the world and pose a major threat to the growth and well-being of the region’s inhabitants.

“Recent assessments show that environmental disasters in the Middle East are injuring and displacing an average of seven million people annually, killing more than 2,600 people and causing material damage,” said Kristalina Georgieva, CEO of the global lender. At the rate of $ 2 billion. The list of catastrophes such as droughts in North Africa, Somalia and Iran, epidemics and infestations of locust herds in the Horn of Africa, severe floods in the Caucasus and Central Asia, are rapidly prolonging.

Based on these assessments; Analysis of data from the last century shows a rise in temperature of up to 1.5 degrees Celsius in this region, which is twice the rate of global warming, which was 0.7 degrees.

Climate change has emerged in the form of a period of drought, successive water shortages or droughts, annual rising temperatures, increasing air pollution in large cities, the occurrence of severe and widespread floods and storms, and have unprecedented effects. These climate changes, especially climate change, have made the human environment more difficult and unhealthy.

Natural disasters are another form of accident and are called a set of harmful accidents that have no human origin. These events are usually unpredictable, or at least have not been predicted for a long time. Each atmospheric element alone can cause significant disasters such as rising temperatures and heat, high wind speeds and hurricanes, thunderstorms and hail, frost and frost, but most of the life and property losses due to combined atmospheric phenomena and secondary hazards These include storms, lightning, droughts, floods and fires.

Natural disasters are phenomena caused by factors imposed on nature, including air pollution, acid rain, increased carbon dioxide and pollutants in the atmosphere and their greenhouse effects, ozone depletion, which is a category of phenomena due to the mechanism and structure of natural factors such as earthquakes. It also includes floods, droughts, desertification, and onshore seawater.
