Since the Industrial Revolution we have been digging up and burning fossil fuels (coal, oil and natural gas). This releases carbon dioxide that has been hidden away for millions of years. The carbon cycle cannot remove this extra CO2 from the atmosphere and it is warming up, causing global warming. We have also cut down forests, thus removing trees that would have taken some of the CO2 out of the air.
