What is the main cause of global warming?

In the last century, the sea level has rose for about 17 centimetres. The rate in the last decade is however, nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up, due to the heat. Not only that, the Greenland and Antarctic ice sheets are melting, glaciers are disappearing and extreme weather events have occurred more often. All these phenomena are the evidence of the fact that the Earth is warming up, they are the cause of global warming. Many scientists and researchers are trying to find a way to reduce the heat that the Earth absorbs. But in order to do that, they need to answer one question: What is the main cause of global warming. Is it we, humans, or is it the sun that causes it? Many debates are being held about this topic. Not only that, even documentaries were made about it, like The Great Global Warming Swindle and The inconvenient truth. But still, no one knows whether we, humans, causes global warming or the sun. To ‘normal’ people it sounds like all these scientists and researchers are making a fuss about something so trivial. But is global warming really a trivial matter or, are the people unconscious about the danger of global warming. If you are conscious about it, you will see that the world is changing slowly due to global warming. Ice is melting worldwide, animals have moved to higher and cooler places, precipitation has increased and an increase of insects. But if global warming continues like this, it can become a disaster. There are possibilities that parts of the world will go under water, because the sea level rises. Floods and drought will occur more often, less fresh water will be available, due to the melting of the ice caps. Not only that, but animal species will be extinct, like the polar bear. Researcher Bill Fraser showed that the numbers of Adélie penguins on...
