It is somewhat ironic – though in some ways unsurprising – that at the time when the climate change activism (or, rather, according to the new guidelines, climate crisis or climate catastrophe activism) is reaching its shrillest heights yet, what with Saint Greta, Extinction Rebellion and widespread “climate anxiety”, the actual science the activists so noisily champion over the (“denialist”) belief is showing positive trends.

For example, the International Energy Agency has reported a few days ago that CO2 emissions have defied expectations by flatlining throughout 2019, even as the global economy continues to grow by almost 3 per cent.
