Global warming could cause more atmospheric rivers, flooding

The video discusses the unusual extreme rainfall in Asia during July 2018 and 2020, prompting scientists to create climate models to study the effects of global warming on rainfall patterns. The research indicates that a 4°C rise in global temperature could increase atmospheric rivers, leading to more frequent and severe flooding in Asia, Europe, and North America. Atmospheric rivers are narrow bands of moist air that can cause heavy rain or snow when they encounter barriers like mountains.

What prompted scientists to create climate models in the study?

• A sudden drop in global temperatures

• The discovery of new atmospheric rivers

• Increased snowfall in Europe

• Unusual extreme rainfall in Asia during specific months

According to the research, what could happen if the global temperature rises by 4 degrees Celsius?

• Stabilization of global weather patterns

• Reduction in rainfall over mountainous areas

• Increase in atmospheric rivers over Asia, Europe, and North America

• Decrease in atmospheric rivers

What are atmospheric rivers?

• Wide bands of dry air

• Narrow bands of very wet air

• Streams of cold air

• Paths of high-pressure systems

How do atmospheric rivers affect mountainous regions?

• They reduce snowfall

• They lead to extreme flooding

• They cause droughts

• They stabilize the climate

What is a potential consequence of a warming planet on atmospheric moisture streams?

• Decrease in global humidity

• Less frequent rainfall

• Stabilization of atmospheric conditions

• More frequent and extreme flooding
