Big miners like Rio and BHP employ many geologists, chemists and physicists who can show that natural climate cycles have been occurring for millions of years. Why, then, are their boards pushing the man-made climate fable?

It’s all about money.

Wind turbines, solar farms and electric cars need humungous amounts of copper, steel, rare earths, lithium, silicon and aluminium for towers, transmission lines, charging stations, generators, motors, panels and batteries.

This means higher metal prices and bigger profits, dividends and bonuses. All pretty simple.

It’s a theory, anyway.
