World weather will be extremely harsh

Before the end of this century, many parts of the world will be faced with more intense heat waves, more intense rainstorms and more prolonged droughts and forecasts.

Before the end of this century, many parts of the world will face more fierce heat waves, more intense rainstorms and longer-lasting drought, predictions by American scientists. in the most recent study.

Research - conducted by a team of scientists at the US National Center for Atmospheric Research - says previous climate studies only consider changes in rainfall or average temperature over the next century. increased greenhouse gas emissions; The study also pays more attention to the harsh changes of weather that may occur.

'These are harsh changes, not mediums, and are the cause of much damage to society and affect many ecosystems,' said Claudia Tebaldi, the lead researcher.

Researchers have relied on simulation work from nine different climatic types in the period 1980-1999 and 2080-2099. These simulations were created on supercomputers in research centers in France, Russia, Japan and the United States. They calculated 10 different climate change indicators, with 5 indicators related to temperature and 5 indicators related to moisture. These 10 indicators include: hot weather, the difference between the highest and lowest temperatures in the year, the length of the season, cold days, hot nights and 5 factors related to rainfall.

Calculations show that between 2080-2099, the number of extremely hot nights and hot periods will increase significantly in nearly all land areas around the world; and on hot or extremely hot nights, the number of deaths could be higher as people have less chance of cooling overnight.

Most of the northern regions will have a temperature of about 40 degrees Celsius, like northern America, Canada; Most European regions have more rainy days. In addition, the dry state can last in the western United States, southern Europe, eastern Brazil and many other places. Dryness is one of many factors that cause and increase drought.

Season times can also be significant in most parts of North America, Europe and Asia.

According to the researchers, reducing greenhouse gas emissions in the next century could reduce the risk of the worst climate change.
