Has climate change been caused by humans?

—The global scientific report blaming carbon emissions for climate change is based on misconceptions about the Earth's behaviour. Australian academic  hypothesis.

 —The Industrial Revolution has contributed to a rise in greenhouse gases in the atmosphere. The energy sector is responsible for about ¾ of the carbon dioxide emissions, 1/5 of the methane emissions and a large quantity of nitrous oxide. It also produces nitrogen oxides (NOx) and carbon monoxide (CO) which are not greenhouse gases but do have an influence on the chemical cycles in the atmosphere that produce or destroy greenhouse gases.
