The climate is changing due to the increase of CO2. Many governments, scientists and even school teachers blame the burning of fossil fuels. But the main origin of the climate change is the population growth. From 1900 the world population grew from 1.6 billion to 7.7 billion today. The CO2 emission pro capita (for each person) 6 metric tons today. The Population growth is the origin of the Climate Change.
The burning of fossil fuels will end in the next 40 years because there will be no oil anymore. See our article The oil runs dry in 30-40 years. The focus on climate change because the CO2 level rises, should be changed to the focus on the energy transition.
