The advocates of man-made global warming meet any meteorological event such as the recent severe winters we have experienced which does not fit into their ideology by chanting one of their favourite mantras ” weather should not be confused with climate”. The problem for warmists is that when weather lasts for years it becomes the climate.
Flows between decades of warmer and colder climate in Britain are the norm. The decades leading up to the 1940s were unusually warm; those from the mid-1940s to the mid 1970s unusually cold. The odds are that we are now reverting to a colder period.
The warmists might care to ask themselves why the period 1945-1975 was unusually cold, when massive increases in man-made greenhouse gases took place during both that period and the warmer decades before 1945.
