Why does our metabolic rate increase in warmer climates?

Question

My first thought is that the metabolic rate should decrease since you lose less energy (heat) to your surroundings. But I read everywhere that climate increases it instead.

Cooling takes energy too. When we are warm, we sweat, so the evaporative cooling on our skin removes more heat. In order to sweat, we need to move fluids through out body to the surface which takes energy (and water).
