What are the impacts of global warming in the UK?
Temp^ Southern England 3.9 2080, W rainfall^35%, S rainfall^50%, energy demand for air conditioning^electricity consumption, sea level rise 13-76cm 2095, droughts increase, temp^longer growing season improve productivity, species move north

What are the impacts of global warming on monsoon climates e.g. Bangladesh?
2.4 2100, longer winter droughts, more rain summer, ^rainfall 10-15%, 20% river discharge, frequency intensity tropical cyclones, sea level 30-100cm submerge 18% land, 13-30million migrate to India, coral reef damaged turtles dolphins affected.

What are the international responses to global warming?
KYOTO PROTOCOL 1997, 190 countries monitor + reduce greenhouse gas emissions, developed c

What are the national responses to global warming?
Carbon capture storage. energy conservation: G pay boilers/insulation. changing energy mix: nuclear, renewable =

What are the human causes of global warming?
Enhanced greenhouse effect: CO2/CFC/M/NOx/O3 absorb outgoing LW radiation, re-emit SW, livestock/farming: >methane/nitrogen fertilizers release NOx, cars/industry/burning FF: coal/natural gas/oil releases CO2, deforestation: act C sinks takes in CO2.

What are the natural causes of global warming?
milankovitch cycles: affects amount sunlight falls on diff latitudes/seasons, WS=ice age, SS=interglacial period. sunspot activity: >insolation/warming, ice age

What are the observations of climate change?
historical records: cave paintings in Greenland, weather reports since 1861.
9 of 11
What is the physical evidence of climate change?
ice cores: ^CO2=warm climate, ^O16=cold climate, sea floor: high O18=cold climate warmer climates O16 in ice released into oceans, sea level change: rias, fjords, submerged valleys, retreating glaciers: distance of rocks from current glacier

What is the biological evidence of climate change?
Pollen analysis: distinctly shaped PG fall peak bogs resist decay. Coleoptera: diff species beetles live diff climatic conditions, dendrochronology: thicker warm wet, narrower cold dry. Radiocarbon dating: compare rates of decay of C14, C12.
