Climate of Brazil Climate of Brazil The climate in Brazil varies considerably mostly from tropical north (the equator traverses the mouth of the Amazon) to temperate zones south of the Tropic of Capricorn (23°26' S latitude). Temperatures below the equator are high, averaging above , but not reaching the summer extremes of up to in the temperate zones. There is little seasonal variation near the equator, although at times it can get cool enough to need to wear a jacket, especially in the rain. Average temperatures below the Tropic of Capricorn are mild, ranging from to . At the country's other extreme, there
The HAB Theory The novel borrows heavily from Brown's theory and book, which is that approximately every 6,000–7,000 years the Earth's polar ice caps become over-burdened with ice, creating such an imbalance in the planet's center of gravity, that the Earth's poles and the Earth's equator shift positions. The former poles are soon located somewhere between the Tropic of Cancer and the Tropic of Capricorn, where the weight of the polar ice cap leaves a large circular depression and other dramatic geological changes occur as the huge quantity of water is released by the ice caps melting. Called "capsizing" in the novel the
