Pretty sure Castro is a sceptic of man-made climate change. Considering the general consensus among climatologists is that humans are responsible for the current state of global warming due to greenhouse gas emissions, that would, shockingly, make Castro a swivel-eyed nutcase who believes in wild conspiracy theories.
Who would've thunk it, eh?
Who was responsible for climate change millennia ago? It was far warmer in this country during Romsn time than now. Did the greenhouse gas emissions causing this comd from 4 wheel drive chariots? They regularly used to hold fairs on the frozen Thames a couple of centuries of so ago. Climates have always changed.
Of course the explosion in population and modern technology has led to an acceleration of change. But the climate has always changed dramatically from extremely hot to ice ages and back again (we spent the 1960s listening to griim warnings about an impending ice age) long before there were any humans on the planet.
