El oscurecimiento global

The video discusses global dimming, a phenomenon where solar energy reaching Earth's surface has decreased due to air pollution. This pollution, consisting of soot and other particles, blocks sunlight and affects cloud formation, leading to a cooling effect. Despite this, global dimming is not enough to stop global warming. Reducing emissions could eliminate global dimming, revealing the true extent of global warming.

What is the primary cause of global dimming?

• Changes in the Sun's intensity

• Natural atmospheric changes

• Increased volcanic activity

• Human-induced atmospheric pollution

How do pollutants affect cloud formation in the context of global dimming?

• They have no effect on clouds

• They lead to the formation of smaller droplets that reflect more sunlight

• They cause clouds to absorb more sunlight

• They make clouds disappear

What is the double impact of pollutants on global dimming?

• They increase the Earth's temperature

• They reduce sunlight and enhance cloud reflection

• They cause more rainfall

• They make the atmosphere clearer

What unexpected effect might occur if air pollution is eliminated?

• A decrease in global temperatures

• A sudden increase in global dimming

• An acceleration of global warming

• No change in climate patterns

Why is it important to address air pollution in the context of global warming?

• To increase global dimming

• To understand the true impact of global warming

• To reduce volcanic activity

• To make the atmosphere more colorful
