This work investigated the trends, concentrations and impacts of some greenhouse gases on the global climate with temperature as an index. Over the years, a lot of awareness has been created worldwide on the dangers of emitting greenhouse gases into the atmosphere. Hence, there is need to ascertain if people have adhered strictly to these warnings. The data used for these analyses are the global average abundances of the major well-mixed, long-lived greenhouse gas, global annual mean Earth surface temperatures anomalies and the annual global land, ocean and global (land-ocean) temperature anomalies for ten (10) warmest years on record. The data were obtained from the National Oceanic and Atmospheric Administration (NOAA) and National Aeronautic Space Administration (NASA). The periods under consideration are 1978-2010 and 1880-2012. The result of the observations and analyses generally revealed that the concentrations of greenhouse gases are still on the increase especially since the industrial revolution and this has caused a corresponding increase in the global temperature. This increase in the global temperature has contributed immensely to the global warming and other attendant climatic problems.
