The origin of  this man made abrupt and catastrophic climate change being experienced around the world is greed...plain and simple- and a good direct example of late is what has happened with flooding in China this last week where 32 million have been affected and 180 people have died. Wuhan, one of the cities affected, is suffering now from the effects of urban development without concern for environmental consequences: "From 1949 to 2015, the number of the lakes in Wuhan’s urban areas dropped from 127 to 40 because they were filled for construction, which effectively makes it harder for the city to absorb flood water."
