Okay, so the original thread was closed because I didn't offer a summary and an opinion on the matter. So here goes...
Summary:
1. The reason why tropical countries aren't developed are because of agriculture and the control of diseases. In the pre-industrial era, tropical countries were at a disadvantage in agriculture. Tropical countries have more biodiversity which means they would suffer from more pests and diseases. Pests and diseases are also harder to control in the tropics than in temperate areas. Tropics have less fertile soil compared to temperate regions. Industrialisation was reached later and tropical countries lag behind even more than before.
2. Brains don't function as well in warm/tropical weather.
Opinion:
As someone who lives in a tropical country I can definitely say that sometimes it is hard to think properly in warm weather.
So stop complaining about Ireland's "bad" weather.
