, weather - ✔✔Local atmospheric conditions (precipitation and temperatures)
over a short period of time. Highly variable hour to hour and day to day.
Climate - ✔✔Regional atmospheric conditions over 30 years. "Average" weather
throughout the year.
Latitudinal Distribution - ✔✔Stronger or hotter at the equator and less at the
poles. Temperature, precipitation, etc. traveling N/S will get different
weather/climates
Biomes - ✔✔Global associations of plants and animals, largely determined by
climate, primarily temperatures and precipitation. (Taiga, savanna, rainforest,
deciduous forest)
inquiry - ✔✔Doing science to learn science
Current CO2 concentration - ✔✔416 ppm
The greenhouse effect - ✔✔- Sun emits solar radiation
- 1/3 is reflected and 2/3 is absorbed
- infrared radiation is emitted from the earths surface
- some passes through atmosphere but most is absorbed and re-emitted as
Greenhouse radiation
- this greenhouse radiation warms the earth
