Deadly floods hit several countries at once

Climate change is increasing the frequency and intensity of storms causing floods and landslides. This is confirmed by recent disasters in different parts of the world, such as India, Japan, China, Turkey and the United States.

The heavy rains that hit New Delhi led to the closure of schools and caused landslides and floods that killed several people. Japan also experienced flooding and landslides due to heavy rain, which killed two people and left several others missing. In New York and Vermont, the floods are considered the worst since Hurricane Irene in 2011.

Atmospheric scientists note that all of these storms form in a warmer atmosphere, making extreme precipitation more common. The main reason for this phenomenon is that a warmer atmosphere holds more moisture, which leads to more precipitation. Pollutants such as carbon dioxide and methane also contribute to warming the atmosphere and trapping heat on Earth.

Meteorologists explain that each degree of increase in the temperature of the atmosphere entails a 7% increase in its capacity for water. According to NASA, the average global temperature has increased by 1.1 degrees Celsius since 1880.

Scientists predict that with additional climate warming, extreme precipitation events will become even more frequent and intense. This is confirmed by climate models that have predicted such events from the beginning.

Gavin Schmidt, climatologist and director of NASA’s Goddard Institute for Space Studies, notes that the regions most affected by climate change are not necessarily the big polluters causing global warming. This indicates that climate change is affecting all regions of the world, regardless of their environmental status.
