According to the researchers, the changing rainfall means that there are large fluctuations between periods of heavy rain and drought. These changes have been observed in about 75 percent of the landmass since the beginning of the last century. These changes worsened in the middle of the last century, and affected Europe, North America and Australia the most.
Scientists point out that greenhouse gases increase rainfall variability because they create warmer, wetter conditions. A 1 degree Celsius increase in temperature increases the atmosphere’s ability to hold moisture by 7 percent, leading to more intense rainfall and sharper swings between wet and dry periods. Every 10 years, daily rainfall variability increases by 1.2 percent.
According to the researchers, these changes are likely to affect more than just rainfall, because they, along with other phenomena associated with climate change, pose a significant risk. This means heavy rainfall with very high temperatures and rising sea levels, which will negatively affect ecosystems and humans. For example, it may lead to a decrease in agricultural production. This is a worrying and noticeable matter.
It is worth noting that scientists announced earlier that the slowdown in global ocean currents will lead to the accumulation of carbon dioxide in the atmosphere, creating a dangerous situation that threatens major climate problems.
