This depends on your point of view.
If the Oregon Report is correct (which I believe it is) there is no such thing as global warming,
On the other hand, most climate scientists say that recent global warming and climate change are caused substantially by human activities, such as burning fossil fuels (coal, oil and natural gas), manufacturing cement and deforestation.
Trees play an important role in global warming by absorbing carbon dioxide and pumping oxygen into the atmosphere.
Lots of roles, they kill and hurt animals alot.
Radiation from the sun warms the earth. Increasing amounts of greenhouse gases prevent this heat from reflecting back out into space, causing a global warming of the atmosphere.

there are holes in the ozone layer which are damaging fresh air .we are exhaling co2 but on the other hand we are cutting trees who give us oxygen.
The albedo effect, characterised by changes in the reflection and absorption of sunlight, does play a small role in global warming, but requires global warming to be underway before it can play that part. As the world warms, ice caps and sea ice melt. Ice reflects much of the sun's energy back into space, but when the ice disappears the open sea and land absorb much of the sun's energy, becoming warmer. This accelerates global warming.
kids must be taught regarding global warming, so that they are not only gain awareness but also work for its counter implementations.
Cities and the people in them play a large role in global warming. Heating, cooling and transport in the cities use massive amounts of fossil fuels (coal, oil and natural gas). When fossil fuel is burnt it releases carbon dioxide, one of the greenhouse gases that are causing global warming.
Trees play an important role in global warming by absorbing carbon dioxide and pumping oxygen into the atmosphere.
Refrigerators usually give out heat, and are usually run on fossil fuel electricity, so, yes, they contribute to global warming. However, they only play a small part in causing global warming. The main causes of global warming are the greenhouse gases released when we burn fossil fuels (coal, oil and natural gas) in transport, industry, and the generation of electricity. That and deforestation.
Everyone can reduce release of Greenhouse Gases. Mostly, cut down on how much energy you use.
till global warming goes away
They don't prevent global warming, they play a small part in reducing global warming. Energy efficient lightbulbs need less energy to produce the same amount of light, as older bulbs also produced heat, which was wasted. Any way of using less energy is useful, especially if everyone does it.
Lots of roles, they kill and hurt animals alot.
Endangered species play a role in mitigating global warming through natural processes. For example, forests inhabited by endangered species absorb carbon dioxide, reducing greenhouse gas emissions. Additionally, certain endangered species may help maintain the balance of ecosystems, which in turn support carbon sequestration. Preserving endangered species is crucial in sustaining these processes and combating global warming.
Radiation from the sun warms the earth. Increasing amounts of greenhouse gases prevent this heat from reflecting back out into space, causing a global warming of the atmosphere.
They play a part by spreading seed from plants and trees, that in turn grow and use carbon to do so.
