Because ocean currents circulate water of different temperatures all over the globe, they often have a significant impact on the world’s climate and weather patterns. The Gulf Stream gathers all of its water from the warm tropical waters of the Caribbean and the Gulf of Mexico causing the areas around it to be warm. Florida and much of the Southeastern United States is mild all year round because of the Gulf Stream.  
The greatest impact the Gulf Stream has on climate is found in Europe. Since it flows into the North Atlantic Current, it helps keep places like Great Britain much warmer than it would otherwise be. This place is also known for its foggy, overcast conditions due to the Gulf Stream. The Gulf Stream and its warm winds are also responsible for keeping northern Norway’s coast free of ice and snow.
