Temperate and polar zones are cooler than subtropical
The climate of the Middle Atlantic states is generally cooler than Florida. While Florida has a humid subtropical climate with warm temperatures year-round, the Middle Atlantic states experience a more varied climate with cold winters and warm summers. This results in lower average temperatures in the Middle Atlantic region compared to Florida, particularly during the winter months.
It was cooler than now
There is a cold ocean current off the US west coast, which creates a cooler climate.
Tasmania is colder than Queensland primarily due to its geographic location and climate zones. Tasmania is situated further south, resulting in a cooler temperate climate, while Queensland is located in the subtropical and tropical regions, which experience warmer temperatures year-round. Additionally, Tasmania's elevation and coastal winds contribute to its cooler weather, whereas Queensland benefits from warmer ocean currents and more direct sunlight.
In the U.S., the states that typically have a humid subtropical climate are primarily found in the southeastern region. However, the exceptions in the southwest include parts of Texas, particularly the eastern regions near the Gulf Coast, which experience this climate. Other areas in Arkansas and Louisiana also fall under the humid subtropical classification, but they are geographically adjacent rather than southwestern. Overall, the humid subtropical climate is not predominant in the southwestern U.S. apart from these areas.
A little cooler than present day Rhode Island.
A subtropical rainforest typically has high temperatures and high humidity throughout the year. It receives abundant rainfall, often more than 60 inches per year. The climate is characterized by mild winters and warm, rainy summers.
Because the climate was cooler than it was in the surrounding desert
Buenos Aires and New Orleans have a humid subtropical climate, characterized by hot, humid summers and mild winters, making them relatively similar. London, on the other hand, has a temperate maritime climate, featuring cooler temperatures and more rainfall throughout the year. While both Buenos Aires and New Orleans experience distinct seasons, London's climate is generally cooler and more stable. Therefore, Buenos Aires and New Orleans share more climatic similarities than either does with London.
In a continental climate region, winter weather is characterized by cold temperatures and significant snowfall, with more pronounced temperature fluctuations due to the lack of moisture. In contrast, a humid subtropical climate experiences milder winters with higher humidity and occasional rainfall, resulting in less snow and more overcast conditions. The presence of moist air in humid subtropical regions often leads to winter storms that can produce rain rather than snow. Overall, the continental climate tends to have harsher, colder winters compared to the relatively mild winters of the humid subtropical climate.
Alaska is farther away from the equator than Hawaii. Hawaii, therefore, has a warmer climate because it has more direct sunlight.
The North Pole gets less direct sunlight than Georgia.
