Climate Change Flashcards
What does earths atmosphere do to energy from the sun
absorbs and reradiates as long wave energy and reflects it
why does weather occur
energy is unevenly distributed in the atmosphere, both air and water distributes it
what is climate
the average of weather that can be summarised in reference to temperature rainfall humidity wind
what are examples of key greenhouse gases
carbon dioxide
methane
nitrous oxide
chlorofluorocarbons
tropospheric ozone
water vapour
what are greenhouse gases
heat trapping gases
what are the sources of methane
decaying organic matter
permafrost
agriculture
fossil fuel
landfill
what are the sources of nitrous oxide
nitrifying bacteria
agriculture(fertiliser)
by-product of fossil fuel
what are the sources of cfcs
propellents, refridgerants, packaging
what are the sources of carbon dioxide
cell respiration
volcanic eruptions
ocean gas exchange
land cover change
fossil fuel burning
what do carbon budgets estimate
the amount of carbon cycled naturally and what is being released by humans
how do scientists estimate the carbon budget
comparing observations of climatic conditions
and using climate models
How will climate change affect rainfall
earth overall will get wetter with regional variation with areas to get much drier
what are the impacts of climate change
increased droughts
food insecurity
flooding
storms
fire conditions
sea levels rise
increased sea temperature
what is the un body for assessing climate change science and what do they do
intergovernmental panel of climate change that produces reports
what are some of the conferences responsible for policy response
cop3 kyoto
cop21 paris
cop29 aszerbaijan
who are the key actors in policy responsee
unfcc
ipcc
fossil fuel sector
who is responisble for reducing emsissions
nationnal governments
financial sector
multi-national/private companies
what is mitigation
adresses the root cause, reduces gas emissions
what is adaptation
dealing with consequences to reduce risks posed by consequences
ways scotland are reducing emissions
transport
industry
agriculture
land-use and forestry
