The greenhouse effect is the way in which heat is trapped close to the surface of the Earth by “greenhouse gases.” These heat-trapping gases can be thought of as a blanket wrapped around the Earth, which keeps it toastier than it would be without them. Greenhouse gases include carbon dioxide, methane and nitrous oxides. - NASA

CO2 concentrations in the atmosphere are now well over 400ppm – their highest levels in over 800,000 years. Globally we emit over 36 billion tonnes of CO2 per year – this continues to increase. There are large differences – more than 100-fold – in per capita CO2 emissions between countries. - Our World in Data

This graph shows how much C02 is produced per person in the following countries. If you click the link above it will take you to data on additional countries. 

 The combined land and ocean temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880; however, the average rate of increase since 1981 (0.18°C / 0.32°F) is more than twice as great. - Climate.gov
