Rather than score points against the messengers, why not look at the graphs they provide and argue the validity of them
the ball then
the graph provided does show cooling and a graph of the last 120 years will show other cooling periods from 1900 for a decade and 1930 for a decade, in the graph those periods have been significantly swamped by subsequent increases
another similarly informed essayist (I think Paul Vautin in a moment of insightfulness once told him "Shut up you shi" over a totally unrelated issue) seams to think every time it rains in his backyard proves global warming is a left wing plot to destroy the capitalist world and the science has no foundation in fact.
you also talk about el nino as occurring during the cooling. El nino is a localised event cantered in the Pacific. and indicated by the Southern Oscillation Index. Other Ocean Based climate drivers are The Indian Ocean Dipole and Southern annular Mode around the Antarctic. These influence Westralia and the southern states respectively.
Isolating these is as informing as checking out whether it has rained in Pierce Akerman's back yard in the last six months to decide if the whole climate world is changing
Hey its a collision sport you need to belt the man every now and then
