Derived from the Ancient Greek κλῖμαξ (klimaks, “ladder, staircase”) and φόβος (phobos, “fear”) it can be defined in at least two ways:
1 The morbid fears of stairs or climbing stairs;
2 The fear of staircases or falling down stairs;
Similar in some ways to Bathmophobia and Descendophobia.
Malcolm doesn’t suffer from climacophobia he’s just such a hamplanet he doesn’t like the work involved.
A better sounding name for an air pollution advocate usually paid by, interested in, or manipulated by the pollution-heavy industries. They usually claim themselves (falsely) to be an expert in environmental sciences. Their mainpurpose is to propagate pro-pollution attitude.
Probably Bjørn Lomborg was the only respectable climate sceptic but for now he does not support his former opinions anymore either.
