Human activity affects the change in rainfall

An international team of researchers, including Canadian Environment Ministry experts, for the first time confirmed in a report on the impact of human activity on the development of rainfall in the 20th century. .

According to the researchers, human activity has significantly contributed to increasing rainfall at the northern latitudes of the Northern Hemisphere, reducing rainfall in the tropical and semi-tropical regions of the hemisphere, but making Increasing humidity in tropical and semi-tropical regions of the Southern hemisphere.

The recorded climate changes can have a significant impact on ecosystems, agriculture and human health.

Scientists worked on 14 climate models and analyzed actual rainfall in areas between 40 ^o Nam and 70 North in the periods of 1925-1999 and 1950-1999.

The results of the study complement another series of studies that have confirmed that global climate changes due to high levels of greenhouse gas emissions from the atmosphere, mainly from the use of gas such as coal and oil. fire and natural gas.
