Carbon Dioxide - burning fossile fuels
Greenhouse gases
Methane - livestock farming
Water Vapour - evapouration from oceans
The Sun emits short wavelength radiation which passes through the
atmostphere and is re-emitted as long wavelenth radiation (IR) by the
earth
Reducing radiaiton to space
Greenhouse gases in the atmostphere absorb heat radiated from the Earth
The IR radiation is radiated in all directions, including back to earth
IR radiation is thermal radiation, so it warms the surface of the earth
The accumulation of greenhouse gases in the atmostphere increases the
greenouse effect, more IR radiation is absorbed and radiated back to
earth Global warming and climate change
This increase the warming effect in the atmostphere - global warming
Global warming is associated with long term changes to weather patterns -
climate change, and rising sea level due to ice caps melting
Since the population has shot up, wev've become more industrialised
Energy consumption
Both these factors mean that energy consuption hs increased
We are burning more fossil fuels, releasing more into the atomstphere
We've had to chop down trees to make space for housing
Deforestation
Plants absorb CO2 by photosynthesis
Enhanced greenhouse effect
Fewer platns mean less CO2 is being removed from the atmostphere
