since the beginning of the industrial revolution (250 years ago), carbon dioxide concentration in the atmosphere has risen from about 280 parts per million to 408 parts per million in 2018. this means that for every million molecules in the atmosphere, 408 of them are now carbon dioxide, the highest concentration in two million years. the data below shows how global temperatures and atmosphere temperature and co2 levels. the data below shows how global temperatures and atmospheric co2 levels have changed from the year 100. use your knowledge of the carbon cycle to explain how human have affected global carbon dioxide levels and temperature levels. use the information and data provided to support your answer.
