However, if I remember correctly, the warming of the weather is following the rate of industrialisation... The rise in the past 150 years has been much stronger than in the previous 200 years. With spikes in in global temperatures rise somewhat correlated to spikes in industrial output.
This is the view advanced by the proponants of anthropogenic global warming. However there are weaknesses to it. For example in the early 1970's there was a dip in temperatures which led to a belief in global cooling and a possible onset of the next Ice Age. There is also now a further backtracking to say that the period 2009 to 2014 maybe a period of cooling due to the lower level of sunspot activity, despite an increase in industrial activity and CO2 oiutputs in developing countries, particulary India and China.
