The document discusses several key factors that influence the climate of Britain: 1) Latitude - Britain's northern latitude means the sun's rays are more concentrated in the south, and the atmosphere scatters more heat near the poles. 2) Prevailing winds - Warm currents from the Gulf Stream moderate Britain's climate, making it warmer than if those currents did not reach its coasts. 3) Proximity to sea - Bodies of water take longer to heat up and cool down than land, so areas near the coast are cooler in summer and warmer in winter.
