What is world climate?
World climate is caused by the sun. Actually without weather there is no climate, because climate is the weather pattern. World climate is the average weather pattern over a long period of time.

Climate and weather are different in many ways. First weather is the condition of the atmosphere during a short period of time. For instance a day can be rainy, cold and stormy and the next day it is sunny, dry and warm. To know the climate scientists study daily weather over many years.

Every single place in this world has climate. Places that are close together have similar climate. Climate has an effect everywhere people live. It can effect the way people dress and what crops they grow.
 

The problem we have today is global warming caused by pollution made by cars and factories. As carbon monoxide rises, it lets the sun pass but it traps in heat like the green house effect. If this keeps happening, our temperature will rise a couple of degrees. That may not sound like a lot but don't under estimate it. It is killing out coral  reefs and without this ecosystem we have no life.

The types of climate are polar, subarctic, desert, and tropical. The types of climate in North America are  arctic, sub arctic, high altitude, dry subtropical, humid mid altitude, temperate marine, hot arid, humid subtropical and interior. The places that are the coldest are the places near the north and south pole. The places near the equator are the hottest places.

Two factors that we have found that affect climate are volcanoes and El Nino. Volcanoes erupting can change climate for months due to the ashes. Ashes block out the sun.
El Nino happens every couple of years. It warms the water in the mid Atlantic Ocean. It also makes water evaporate into the atmosphere. This causes the driest places to get torrential rainfall and the wettest places to get a major drought.
 

Different places have different climates. For example where we live (Florida) would be considered a subtropical moist. Subtropical moist would have  warm to hot summers and cool winters. Another example of subtropical moist is Buenos Aires in South America.
