DO THIS CODE RED: 1. Write down HW in your agenda 2. Take Off: a) Moon Phase and Tides b) Open textbooks to page 433, and write questions and answers for questions 3 and 4 in your notes

DO THIS:   10 – 15 million years ago, global temperatures were 10 to 11 degrees F   warmer than today.   Greenhouse Effect:   1. Carbon Dioxide, Methane, Nitrous Oxide, and Water Vapor trap heat in atmosphere   2. Vostok Ice Core Samples show carbon dioxide levels going up and down over 800,000 year period (peaking at 300 parts per million)   million years ago, Miocene Epoch, carbon dioxide levels, thought to be over 400 parts per million   Oceans up 100 feet higher (first humans 1 – 2 million yrs ago)   Natural Climate Influences:   Atmosphere:   El Nino and La Nina   Geology:   Volcanic Eruptions   Continents Moving   Geography:   Polar Regions (reflecting radiation)   Physics of Earth:   Orbital changes of the Earth   Extraterrestrial:   Solar Variation     Potential Human Influences on Climate:   Farming: Deforestation and more livestock   Industrial Processes (Industrial Revolution late 1700s to early 1900s)   Factory effluents   Fossil Fuel burning   Automobile exhaust   Landfills release carbon dioxide and methane   Methods we can use to reduce greenhouse gases:   Recycle   Conserve Water   Conserve Energy   Alternative Energy   Electricity (though much is still made by coal burning)   Biofuels (energy from animal and plant products, but can be costly and lead to more farming)   Solar (but still expensive, doesn’t produce speed or power of fossil fuels, and not as efficient when sun is blocked)   Ice Cores:   Scientists drill into ice for ice cores (cylinder of ice, some almost 2 miles deep)   Ice cores have air bubbles frozen inside   Proxy: things (indirect measures for research) that give us clues about the past:   Tree rings   Fossils   Ice Cores   Lake Sediments

DO THIS   4. Oceans up 100 feet higher (first humans 1 – 2 million yrs ago)   Natural Climate Influences   1. Atmosphere:   El Nino and La Nina   2. Geology:   Volcanic Eruptions   Continents Moving   3. Geography:   Polar Regions (reflecting radiation)   4.

Methods we can use to reduce greenhouse gases:   Recycle   Conserve Water   Conserve Energy   Alternative Energy   Electricity (though much is still made by coal burning)   Biofuels (energy from animal and plant products, but can be costly and lead to more farming)   Solar (but still expensive, doesn’t produce speed or power of fossil fuels, and not as efficient when sun is blocked)   Ice Cores:   Scientists drill into ice for ice cores (cylinder of ice, some almost 2 miles deep)   Ice cores have air bubbles frozen inside   Proxy: things (indirect measures for research) that give us clues about the past:   Tree rings   Fossils   Ice Cores   Lake
