Note that South America is quite pink in the map you posted, particularly the Amazon basin. Note also that radiation isn't strictly a function of the average temperature, but the average fourth power of the absolute temperature. I'll explain that to you if you ask nicely. Extreme conditions, such as are experienced in the central Sahara and Arabian peninsula in the summer, strongly perturb the result.

I don't understand. I've never had the slightest wish to live in North Texas.
