greenhouse gases and climate change

• carbon dioxide, methane and water vapour are green house gases that act as an insulating layer in the earths atmosphere
• greenhouse gases don't absorb the incoming short wavelength radiation, but they do absorb the long wavelength radiation that gets reflected back off earth
• the longwave radiation is thermal radiation, so it results in warming the surface of earth. this is the greenhouse effect
• deforestation reduces photosynthesis
• agriculture - farm animals produce methane through digestion processes
• waste release CO2 and methane through decomposition
• stories of climate change may be biased and need to be peer reviewed
• an increase in global temperature can lead to caps melting, rise in sea levels, increase floodings in coastal areas and coastal erosion
• changes in rainfall pattern and changes in temperature causes some regions to struggle to produce food
• changes in temperature and water availability can affect wild species leading to change of their distribution
