Are Humans the Cause Global Warming?

Many people believe that Global Warming is caused by humans burning fossil fuels and putting large amounts of carbon dioxide into the atmosphere. This is not true; in fact global warming is caused by a natural climate cycle. This cycle has been happening before humans began to inhabit the Earth. So humans should be blamed for this natural process. Humans are responsible for 1% of the carbon dioxide in the atmosphere, so we are not to blame. We are facing global warming because from1940-1980 the Earth faced a global cooling.Now it is reversing and it is getting warmer, but eventually the temperature will even out and be back to normal. For example, the eruption of Mount Saint Helens actually cooled the Earth by 1 degree. Humans cause minimal damage to the environment, but nature on the other hand makes a massive impact. Carbon dioxide life span of 20 years and global warming can be reversed in 10- 20 year. If humans are the cause for global warming then the Earth would have been destroyed a long time ago.We did not contribute much to the atmosphere to harm it in any way. So, we shouldn’t be blamed for the cause of global warming. Humans are not the cause for global warming so, we should not be blamed for it. Nature is taking its toll on Earth and humans are being blamed for it. Humans only cause 1% more per year more than last tear. Carbon dioxide has a life span of 20 years so, it will go away eventually. Humans do not cause these problems; it is nature doing its job, so we humans should not be blamed for it.
