B. World Climate Regions
a. Weather: short term, day to day expression of atmosphere processes

c. Climate region: Boundaries drawn around area with similar average climate conditions
d. Climograph: Provide average high and low temperature and precipitation for every month in an entire year.
C. Global Warming
a. Human activities: connected with economic development and industrialization affect the worlds climate
b. Anthropogenic: (human caused) pollution increase the natural greenhouse effect.

4. Effects of global warming include:
Computer models and scientists are coming to agreement on effects

Global average temps increase 2 to 4F by 2030

Major shifts in agriculture areas

Rising sea levels as polar ice caps melt endangering low lying islands around the world, and crustal areas elsewhere
D. Globalization and Climate Change: the international debate on limiting greenhouse gases
a. Rio de Janeiro, Brazil: 1st international agreement on global warming 167 countries agreed to reduce greenhouse gases by certain date
b. Worst offenders: U.S.A., Japan, China,
c. Kyoto, Japan: 38 industrialized countries agreed to reduce their emissions of greenhouse gases to below 1990 levels to take effect countries emitting 55% of worlds greenhouse gasses must ratify them
