Frog book ch. 16:
Greenhouse effect (demo)
Greenhouse gases:
water vapor, CO2, methane (CH4), N2O
See AGGI graph
Gases are transparent to visible light, but not infrared (IR) light
Demo: IR camera, glass
latitude, sunspots, wind patterns (review)
thermo (heat) haline (salt) circulation
also known as NADW (north atlantic deep water)
El Nino, la nina, make sure you understand normal and El Nino
Normal = happy Peruvian fisher peeps
El Nino = heat in mid pacific, reverse current, sad fisher peeps
climate impacts: latitude, moisture content, volcanoes, vegetation (see also deforestation, desertification, melting ice caps)
IPCC
Precipitation ∆
melting glaciers
sea level change (just from heating water, expansion, not yet from polar ice caps melting)
Permafrost melting (positive feedback, thermal runaway)
Proxy indicator: ice cores, sediments, tree rings
Causes: fossil fuels (carbon dioxide), land changes,
Impacts: habitat changes, diseases (e.g. malaria), coral bleaching (see carbonic acid, pH changes), delta salinization (Pearl river delta), watershed damage, water supply (Himalayas)
response: what you can do-think globally, act locally
efficiency, conservation, food miles, building energy, transportation changes (EV, hybrid)
reforestation, cap and trade, carbon tax (likely in your lifetime), carbon offsets
carbon sequestration-nice idea, not practical yet (dangers)

UNFCCC
United Nations Framework Convention on Climate Change (UNFCCC)
Montreal protocol-success
Kyoto-2005-US did not sign (why?)
Copenhagen-2009 non-binding
Paris agreement (12.2015) universal, legally binding
http://ec.europa.eu/clima/policies/international/negotiations/paris/index_en.htm
Governments agreed
