Which is hotter, Britain or America?

First of all, climate and temperature are different, and climate is not just temperature. But I think you must be asking about the general climate of the two places. Britain is an island country with a typical temperate maritime climate, with slight plane crash and less extreme temperature. The United States is too big, and the climate difference is obvious. For example, there are great differences between new york and Miami, one is temperate continental climate, and the other is subtropical monsoon climate. In addition, the United States is prone to extreme temperatures in winter and summer because of the central plains. Or cold wave or heat wave!
