According to Donald Trump, climate change is “the greatest con job ever perpetrated on the world”. The US president also added, when talking to the UN General Assembly in September, that renewables “are a joke; they don’t work”. Why, I wonder, should he limit himself to lobbying for the Nobel Peace Prize? A Nobel Prize in Physics should clearly be on the way.
Does Mr Trump consider why the Earth is not as cold as the Moon? Does he consider the possibility that this has something to do with the atmosphere and, if so, that changes in its composition might alter the way it behaves?
Moreover, is it not possible that even quite a modest change in temperature (relative to absolute zero) might matter a great deal to life forms adapted to today’s biosphere?
In a recent open letter, Bill Gates, no climate denier, remarked that: “Although climate change will have serious consequences — particularly for people in the poorest countries — it will not lead to humanity’s demise.”
