TRANSCRIPT
Volcanic eruptions: release tiny ash particles into atmosphere which can block solar radiation and cool the planet
Eruptions & Cimate
Sunspots: cooler areas of sun cooler planet
Earth rotation: precession, nutation, eccentricity can change climate either way
Carbon dioxide(CO2) – from fossil fuel and plant burning (50-120 years in atmosphere)
Methane: from landfills, fossil fuel production, cow farts (12-18 yrs in atmos) 23 times the warming potential of CO2Methane Capture
Water Vapor: from evaporation (inc. with temp inc)Leads to increasing cloud cover and storms
Greenhouse Gases
Photosynthesis vs. Respiration
Deforestation-releasing carbon that was stored in trees and preventing future storage of CO2
Plankton: main photosynthesis organisms
Ocean Acidification: caused by increasing CO2 amounts in oceans (Carbonic Acid)Destroying coral reefs (home to most fish)
Carbon Cycle
Albedo: ability of a surface to reflect lightSnow/ice is better than water/dirt (less snowmore
heat)
Heat Island: area of increased heat absorption by surfaces(associated with urban areas-asphalt & buildings)
Green Roof: covered in vegetation instead of dark surfaceCovered by solar panels??
Chicago city hall
Anthropogenic: human-centeredHuman impacts on climate change?
Mitigate: to make less severeways humans can lessen impacts on
climate?
Thermal expansion: when water heats up it increases in volume
Sea level rise: thermal expansion and melting ice caps lead to higher sea levelsDoes the melting polar ice raise sea levels?
Coal: mined from ground (US supplies)Oil/petroleum: drilled from underground
(OPEC)Natural Gas: Fracked from underground (US)
Acid rain: burning of fossil fuels releases sulfur dioxide particles which lead to acid rain
Fossil Fuels
Solar: photovoltaic panels convert sunlight directly to electricity (StrataSolar)
Wind:Biofuel:Hydroelectric:Hydrogen fuel:Nuclear: uses Fission (split Uranium into
smaller atoms releasing energy)
Tidal/wave power:Geothermal:
Alternative Energy
