How is it hotter in the northern hemisphere than the south?

The northern hemisphere experiences more intense heat during summer due to its greater landmass, which heats up more quickly than oceans. Additionally, the northern hemisphere has more densely populated and developed regions that can contribute to localized warming. Seasonal variations, such as the tilt of the Earth's axis, also mean that the northern hemisphere receives more direct sunlight during its summer months compared to the Southern Hemisphere.
