Carbon Dioxide
Humans release it through car exhausts, industrial processes as we burn fossil fuels, etc. Deforestation - many people are cutting down large areas of forest for timber and to create more land for farmers.

Methane
Produced naturally in various sources, e.g. rotting plants in marshland. There are two 'man-made' sources which are increasing the amount of methane - rice growing and cattle rearing

Nitrous Oxide
Released naturally by bacteria in soils and oceans. Adding fertiliser increases the amount of nitrous oxide in the soil. It is also released through vehicle engines and industry

CFCs
Man-made chemicals that were once used in aerosol sprays (e.g. deodorant) and are very powerful greenhouse gases. Most countries have stopped producing them as they damage the ozone layer, this prevents UV radiation from reaching the Earth

But some CFCs still remains and gets released, e.g. through leaks from old fridges
