Notes on Global Warming

• Human settlement and food production are linked to the weather and climate.

• If a drought is in one part of the world, the socioeconomic repercussions are all over the world.

• There are 5 main factors of climate: solar energy, latitude, interaction between land and water, world pressure systems, and global wind patterns.

• The natural process of atmospheric heating is the greenhouse effect. It traps the solar radiation in the lower atmosphere that makes a warm envelope surrounding Earth.

• Interaction between land and water- land areas heat and cool faster than water which is why the temp. extremes from hot summers and cold winters away from coasts.
• Continentality- to describe inland climates with hot summers and snowy cold winter.
• Maritime climates- those close to the ocean have cold cloudy summers and winter that are subfreezing.

• Global Pressure Systems- Uneven heating of Earth because of latitudinal differences and the pattern of high and low pressure cells that drive the world's wind and storm systems.

• Global wind patterns- pressure systems that also produce global wind systems.
• Air flows from high-pressure to low pressure.
