Consider the following statements regarding Earth's heat distribution and its effects: 1. The overall heat budget of Earth is always perfectly balanced at all latitudes, meaning heat trapping by greenhouse gases has no local geographical impact. 2. The net solar energy surplus region lies between 40° North and 40° South of the equator, while the energy-deficient regions lie between 40° and 90° latitude in both hemispheres. 3. The latitudinal surplus and deficit of heat energy received by Earth give rise to both global atmospheric and oceanic circulations. How many of the above statements are correct?
