Global dimming occurs when the clouds in the sky reflect the sun's energy back into space. It is also caused by greenhouse gasses. Global dimming can be dangerous because it indirectly causes crops to die, and the waters in the world's oceans to become cooler.
Reducing global dimming can be achieved by decreasing air pollution, particularly from aerosols that reflect sunlight. This can be done by transitioning to cleaner energy sources, such as wind, solar, and hydroelectric power, and implementing stricter emissions regulations for industries and vehicles. Additionally, promoting reforestation and sustainable agricultural practices can enhance air quality and contribute to reducing particulate matter in the atmosphere. Lastly, increasing public awareness and support for policies aimed at improving air quality can further aid in mitigating global dimming.
Global dimming is a decrease in the amount of sunlight landing on earth that was measured between 1950 and 1990.It was caused by pollutants ('particulates') like sulphate aerosols ('floaters') in the air which absorbed and/or reflected solar energy, producing a slight cooling of the atmosphere, hiding the build-up of greenhouse gases.Anti-pollution laws gradually made the air cleaner and the cooling effect also disappeared. There is now no global dimming.
The gas emitted from both ends of a cow is methane, which is a dangerous greenhouse gas, twenty-one times more powerful than carbon dioxide. Methane is causing additional global warming. And it's dangerous to stand too close with a cigarette or a naked flame!A cows fart is dangerous as it produces methane gas. Which is contributing to global warming
Dangerous in what way? hydrogen just being burned does not contribute to global warming, but what about 'making' the hydrogen? Does that use other fuels that contribute to global warming? Hydrogen is more explosive if that is what you mean by dangerous. Hydrocarbons burn to form carbon dioxide which contributes to global warming.
If global cooling means the gradual cooling into an Ice Age, then that has happened in the past and it has taken thousands of years to happen. The present global warming has all happened far faster, in less than 200 years, and is threatening all life on the planet if we can't stop it. Global warming is by far the more dangerous situation.
To battle Global Dimming we could try to reduce aeroplane contrails and to be done on a Global scale we would see a large increase in Global Warming.
Global dimming is a gradual reduction of global direct irradiance, or electromagnetic radiation, that hits the Earth's surface. The process interferes with the hydrological cycle.
Global dimming stops the sun's heat and light reaching the earth. If this lasts for a long time it could cause much loss of life. Global dimming is one suggestion for the death of the dinosaurs.
Global dimming was a time in the last century when temperatures were cooler because there was so much pollution in the air that it reflected away some of the sunlight. This was not a good situation. If global dimming returned the earth might be cooler, but the air would be more polluted causing lung diseases and other undesirable effects.
Aerosols
Global warming is the observed increase in temperature caused by the increase of greenhouse gasses. Greenhouse gasses warm the planet by trapping infrared radiation and slowing its escape into space. Global dimming could roughly be described as the opposite. It is caused by fine particles in the atmosphere (known as "aerosols"). These particles reflect sunlight away, reducing the overall amount of radiation that enters the planet. This has a cooling effect.
because it's effect a lot of everything
Volcanoes release sulfur dioxide gas and ash into the atmosphere during eruptions. This can lead to the formation of sulfur aerosols, which reflect sunlight back into space and cause global dimming by reducing the amount of sunlight reaching the Earth's surface.
Keep the air clean with Clean Air Acts around the world.
Global dimming happens for a few days after a volcanic eruption, when the air is full of ash and particulates that block the sun. So the earth cools for a few days. There were some years between 1960 and 1990 when the sun's radiation by about 4% by smoke from bush fires, pollution and particulates in the atmosphere, particularly sulphate aerosols. So global dimming is usually man-made, except after a volcanic eruption.
Yes, as light pollution radiates the earth's atmosphere with carbon. No one knows exactly how well will it work if EVERYONE turned off their lights, but maybe we can dim our A/C output a bit after a month of dimming lights :D
Global dimming is caused (in theory) by the contrails of planes flying at high altitudes. It is primarily a fools errand to chase this logic. Albedo is a desired issued according to most and this is such a small amount of added albedo to our planet. It is basically alarmist foolishness.
