If the inclination of Earth's axis were increased, which of the following would be a result? The Tropic of Cancer and the Tropic of Capricorn would be closer to the poles, expanding the region between them where the Sun's rays strike Earth vertically between solstices.

Calgary, Alberta, Canada, and London, England, are both situated at approximately 51°N latitude. The winter climate in Calgary is much harsher than that experienced in London. Which is the most significant reason the two cities have such different climates?
